35 melhores ferramentas de IA em 2025 (selecionadas e testadas)

The best AI tools in 2025 were not the ones with the loudest launch — they were the ones still running a year later under the same name. That turns out to be a real filter. Between then and now, coding assistants were renamed, model versions rolled over several times, and pricing pages were quietly rewritten. This guide keeps all 35 picks, but every product name, model version and price below has been checked against the vendor's own page rather than copied forward.

Where a product has been renamed or folded into something larger, it is listed under its current name with the old one noted, so you can match it to whatever you read elsewhere. Where a price could not be confirmed on the vendor's own site, it is described in general terms instead of guessed at.

The 35 tools are grouped into seven categories — writing, images, video, coding, marketing, workplace productivity, and audio — with five picks each. Start with the verified pricing table if you are comparing costs, or jump to the category you actually need.

Verified pricing at a glance

These figures come from each vendor's own pricing page. Where a page did not publish a figure in a machine-readable form, the cell says so rather than inventing one. Prices are per user per month unless noted, and annual billing is shown where it differs.

Tool	Category	Free tier	Paid plans (from vendor's pricing page)
ChatGPT	Writing	Yes, $0	Go, Plus and Pro tiers listed; figures not published in the page text
Claude	Writing	Yes, $0	Pro $20/mo ($17/mo billed annually); Max from $100/mo
Notion (with Notion AI)	Writing	Free plan with limited AI trial	Plus $10/user/mo; Business $20/user/mo — AI now included, not a separate add-on
GitHub Copilot	Coding	Yes, $0	Pro $10; Pro+ $39; Max $100
Amazon Q Developer	Coding	Yes, limited agentic requests	Pro $19/user/mo
Replit	Coding	Starter, free	Core $20/mo ($17 annually); Pro $100/mo; Enterprise custom
Synthesia	Video	Basic, $0	Starter $29/mo ($18 annually); Creator $89/mo ($64 annually)
Jasper AI	Marketing	7-day trial	Pro $69/seat/mo ($59 annually); Business custom
Surfer SEO	Marketing	No	Discovery $49/mo, Standard $99/mo, Pro $182/mo (billed yearly)
Otter.ai	Productivity	Basic, free	Pro $16.99/user/mo ($8.33 annually); Business $30/user/mo ($19.99 annually)
ElevenLabs	Audio	Yes, $0	Starter $6/mo; Creator $22/mo; Pro $99/mo; Scale $299/mo; Business $990/mo

Two things stand out. Coding assistants have converged on roughly $10–$20 a month for an individual seat, while marketing suites sit an order of magnitude higher because they are sold as team software. And almost every category now has a genuinely usable free tier, which means you can test before you commit. If you want to sanity-check the output length of anything these tools produce, a plain word counter is faster than trusting the model's own estimate.

Best AI writing tools

Writing assistants do far more than produce paragraphs. They research, outline, restructure, criticise a draft and hold a long document in context. These five are the ones worth a subscription in 2025.

If you are choosing AI tools for writing, the deciding factor is usually context length and how well the tool handles your own source material, not raw prose quality — every model on this list writes competently.

ChatGPT

OpenAI introduced GPT-5 in 2025, and the line has moved on since: the current ChatGPT pricing page lists GPT-5.6 Luna across its tiers and GPT-5.6 Sol Pro as the advanced reasoning model on the Pro plan. If you saw this article when it referred to "ChatGPT-5", that is the same product a few versions later.

It remains the broadest generalist — drafting, reasoning over uploaded documents, image input, code, and data analysis in one place. The free tier is genuinely usable, and the paid Go, Plus and Pro tiers mainly buy you higher limits and access to the stronger reasoning models.

Use it when you want one tool that is good at almost everything. Use something narrower when you need a specific workflow.

Claude

Claude is Anthropic's assistant, and its model lineup has moved well past the Claude 4 generation this article originally named. The pricing page currently lists Opus 5 for complex agentic and enterprise work, Sonnet 5 for coding and agents, Haiku 4.5 as the fast, low-cost option, plus Fable 5.1 and Mythos.

Claude's strength is long-document work: feeding it a large report, contract or codebase and asking questions against it. It is also noticeably more willing to say it is unsure, which matters when you are checking facts rather than generating filler.

Pricing is Free, Pro at $20 a month ($17 billed annually), and Max from $100 a month.

Notion AI

Notion changed how its AI is sold. It is no longer a separate add-on with its own line item — AI is now included in the paid plans, with the free plan offering a limited trial. Plus is $10 per user per month and Business is $20.

The advantage is context: Notion AI is answering against your own wiki, notes and databases rather than the open internet. Summarising a project page, autofilling a database column, or drafting from your own meeting notes is where it earns its place.

Newer agent features run on a credits system, priced separately from the base plans.

Writesonic

Writesonic is built around marketing output rather than open-ended chat: landing pages, ad copy, product descriptions and SEO-oriented articles, with brand voice settings and bulk generation.

It suits people producing a high volume of similar assets, where templates and consistency matter more than nuance. If you write a handful of considered pieces a month, a general assistant will serve you better.

Whatever you generate, run it past an AI content detector and an AI grammar checker before it ships under your name.

Perplexity AI

Perplexity AI is an answer engine rather than a writing tool, and that is precisely why it belongs in a writing workflow. It searches, synthesises and — critically — cites, so you can click through to the source instead of trusting a summary.

Use it for the research pass, then write elsewhere. The citation trail is the feature; treat an uncited claim from any assistant as unverified. Perplexity offers a free tier alongside a paid Pro subscription.

Best AI image-generating tools

Image generation went from novelty to production tool fast. The practical differences now are licensing, control over composition, and whether the output survives a client review. These five cover the range, and you can compare them against a general-purpose AI image generator before paying for anything.

One caution that applies to every tool in this section: check the licence terms for commercial use, and keep a record of what was generated. Transparency obligations around AI-generated media are tightening, and reconstructing provenance later is painful.

Midjourney

Midjourney still sets the aesthetic benchmark. The version number in this article's original text — v6 — is well out of date: Midjourney's own site currently announces V8.2 as live, so treat any guide still citing v6 as stale.

Its strength is coherent, stylised, art-directed output from short prompts. Its weakness is precise control: if you need a specific product in a specific position, you will fight it. Midjourney is subscription-only, with no permanent free tier.

Adobe Firefly

Adobe Firefly trades some raw flair for commercial safety. Adobe trains on licensed and public-domain material and positions Firefly as commercially safe to use, which is why it shows up in corporate workflows where provenance questions get asked.

It integrates directly into Photoshop and the wider Creative Cloud, so generative fill and expand sit inside an editing pipeline rather than in a separate tab. For teams already paying Adobe, it is the path of least resistance.

Google Imagen 3

Imagen 3 is Google's text-to-image model — note that the correct product name is Imagen, not "Image 3", and that the link here is to a third-party interface rather than Google's own console.

Imagen's advantage is prompt adherence: it tends to render what you actually asked for, including text within images, which most models still handle poorly. That makes it a better fit for signage, mockups and anything where the words in the picture have to be right. Google's AI announcements move quickly — our roundup of Google I/O AI updates covers the wider platform picture.

Leonardo AI

Leonardo AI is the control-oriented option. Fine-tuned models, custom model training, pose and depth guidance, and a canvas editor give you far more say over composition than a pure prompt box.

It has become a staple for game art, concept work and anyone producing many assets in one consistent style. There is a free daily credit allowance, which is enough to judge whether it fits your workflow.

DALL·E 3

DALL·E 3 is OpenAI's image model, and its distinguishing feature is conversational iteration: because it sits inside ChatGPT, you refine an image by describing the change in plain language rather than rewriting the whole prompt.

It handles natural-language instructions and in-image text well, and it is the fastest route from idea to acceptable image for anyone already using ChatGPT. As with Imagen above, the link here points at a third-party site rather than OpenAI's own.

Best AI tools for video creation

Video is where AI has changed unit economics most sharply. A training video that once meant a studio, a presenter and an edit is now a script and a render. These five cover avatars, generative footage and editing. For the reverse problem — extracting the substance out of a long video — an AI video summarizer is faster than scrubbing the timeline.

Synthesia

Synthesia is the avatar-video standard for corporate training, onboarding and product explainers. You type a script, pick a presenter and a language, and get a finished video without a camera.

Its real advantage is maintenance: when a policy changes, you edit one line of script and re-render, instead of rebooking a shoot. Pricing runs Basic at $0, Starter at $29 a month ($18 billed annually) and Creator at $89 a month ($64 billed annually), with Enterprise on request.

Runway

Runway pushed generative video into practical use with its Gen series, and the model line has iterated well past the Gen-3 Alpha named in this article's original text.

Beyond text-to-video, its value is the surrounding toolkit: inpainting, motion brush, background removal and frame interpolation. It is best understood as a generative post-production suite rather than a one-click video maker.

Pika

Pika targets short-form social video, and like every model on this list it has shipped several versions since the 2.0 release originally cited here.

It is quick, playful and good at effects-led clips built for vertical feeds. Expect a few seconds per generation rather than a finished narrative sequence — that is the format it is designed for.

DeepBrain AI

DeepBrain AI is another AI-avatar platform, competing directly with Synthesia in the talking-head and virtual-presenter space, with a strong focus on realistic humans and multilingual delivery.

It is worth trialling against Synthesia rather than assuming equivalence: avatar quality, language coverage and pricing differ enough that most teams have a clear preference after one test script.

Descript

Descript is the one tool here that changes how editing feels. It transcribes your video, then lets you edit the footage by editing the transcript — delete a sentence and the corresponding video goes with it.

Filler-word removal, studio sound and overdub make it the default for podcasters and anyone producing talking-head content regularly. It offers a free tier plus paid per-person plans, with a discount for annual billing.

Best AI tools for coding

This category changed names more than any other since 2025, so read the labels carefully — two of the five below are the same products under new branding. If you just want to sketch a function without installing anything, an AI code generator in the browser will do for small jobs.

GitHub Copilot

GitHub Copilot is the default. The "Copilot X" branding used in the original version of this list was a 2023-era preview name and is no longer how the product is sold.

Current plans, straight from GitHub's pricing page, are Free at $0, Pro at $10 per user per month, Pro+ at $39 and Max at $100, with the higher tiers adding monthly AI credits for chat, agents and code review. Autocomplete is now the least interesting part; the agent and review features are what justify the paid tiers.

Replit Agent

Replit's AI assistant is no longer called Ghostwriter — the current branding on Replit's own pricing page is Replit Agent, and the plans are Starter (free), Core at $20 a month ($17 billed annually), Pro at $100 a month, and Enterprise on request.

What makes it distinct is that the AI, the editor, the runtime and deployment all live in the browser. You can go from prompt to a running, hosted app without a local toolchain, which is why it is popular for prototypes and for teaching.

Tabnine

Tabnine competes on privacy rather than raw capability. It offers self-hosted and air-gapped deployment and is explicit about not training on your code, which is what gets it through procurement at companies where Copilot does not.

It supports the mainstream IDEs and can be tuned on your own repositories so suggestions match your house conventions. If your blocker is legal rather than technical, this is the one to evaluate.

Amazon Q Developer

Amazon's coding assistant is now Amazon Q Developer, not CodeWhisperer — that name has been retired. AWS's pricing page lists a free tier with limited agentic requests per month, and a Pro tier at $19 per user per month adding higher limits, identity centre support and IP indemnity.

Its differentiator is AWS fluency: it understands your services and IAM context, and it handles large-scale code transformation jobs such as Java and .NET upgrades, which is a genuinely tedious problem to automate.

Cursor

Cursor is an AI-first editor rather than a plugin. Because the assistant is built into the editor rather than bolted on, it can reason across your whole repository, apply multi-file edits, and take an instruction like "rename this concept everywhere" seriously.

For developers doing substantial refactoring rather than line-by-line completion, this architectural difference is the whole point. It offers a free tier with paid plans above it.

Best AI tools for marketing

Marketing tools are sold as team software, which is why the prices in this section are the highest on the list. Judge them on workflow and integration rather than on writing quality. For the groundwork, our SEO tools and a free keyword research tool will get you a long way before a paid suite is justified.

Jasper AI

Jasper AI is aimed squarely at marketing teams that need consistent brand voice across many people and channels, with campaign workflows, brand guidelines and knowledge bases built in.

Its pricing has consolidated: the current page lists Pro at $69 per seat per month ($59 billed annually) and a custom-priced Business plan, both with a seven-day trial. That is enterprise pricing, and it only pays off if several people are producing content weekly.

Surfer SEO

Surfer SEO connects writing to ranking data. It analyses what is currently ranking for a term and produces a concrete brief — terms to include, target length, heading structure — then scores your draft against it.

Billed yearly, the current plans run Discovery at $49 a month, Standard at $99, Pro at $182, and higher tiers above that. Treat its content score as a guide rather than a target; writing purely to the number produces exactly the sort of page readers bounce off.

HubSpot AI

HubSpot AI is not a standalone product but a layer across HubSpot's CRM, marketing and service tools — drafting emails, scoring leads, summarising conversations and generating landing pages against your actual customer data.

That context is the value. Generic tools do not know which deals are stalling. If you already run HubSpot, this is included capability rather than another subscription.

Copy.ai

Copy.ai has moved beyond short-form copy generation into go-to-market workflow automation — chaining steps such as researching an account, drafting outreach and enriching CRM records.

Think of it as automation with language models inside, rather than a blank page with a prompt box. That repositioning makes it more useful to sales operations than to individual copywriters.

MarketMuse

MarketMuse is still operating independently — its site carries a current 2026 copyright notice, so reports of its disappearance are wrong.

It works at the level of topic authority rather than the single page: auditing everything you have published on a subject, finding the gaps, and prioritising what to write next. It is a planning tool for sites with a large existing library, not a drafting tool.

Best AI tools for workplace productivity

AI has become a reliable meeting assistant: taking notes, tracking action items and tidying up written communication. Nobody has to volunteer to write the minutes any more. These five are the ones that stick after the novelty wears off.

Fireflies AI

Fireflies AI joins your calls, records them, and transcribes in real time, producing a searchable record with action items pulled out and highlights you can share immediately.

The point is not the transcript itself but not having to hold the meeting in your head. You stop taking defensive notes and actually participate, then search for the detail afterwards.

ClickUp AI

The ClickUp AI layer sits inside an already dense project management platform: writing task descriptions, summarising long project documents, and generating ideas for the next sprint.

Its value scales with how much of your work already lives in ClickUp. It shortens status updates and keeps things organised when a team is juggling many deadlines — but it is not a reason to adopt ClickUp if you are not already there.

Otter.ai

Otter.ai is the on-the-fly transcription companion for meetings, lectures and interviews. It captures every word, tags speakers, and lets you highlight key moments, search for specific phrases and share notes so the team stays current.

Current pricing is Basic free, Pro at $16.99 per user per month ($8.33 billed annually), Business at $30 per user per month ($19.99 billed annually), and Enterprise on request. For students and interviewers, the free tier often suffices.

Grammarly

Grammarly does far more than correct spelling and grammar. It is an AI writing assistant that will draft an email, rephrase a sentence or adjust your tone so the message lands as intended.

It learns your style and adapts — a formal register for clients, a looser one for your team — and it works everywhere you type rather than in a separate app, which is why it survives when standalone tools get abandoned.

Zoom AI Companion

The Zoom AI Companion joins your video calls and summarises the conversation, surfaces key decisions and drafts follow-up emails, so you move straight from the meeting into the work rather than into writing it up.

Its advantage over standalone note-takers is simple: it is already in the call, with no bot to admit and no extra licence to buy if you are on an eligible Zoom plan.

Best AI tools for audio, music and voice generation

AI has changed the sound industry as much as any other. Studio-quality voice-over, original scoring and real-time voice changing all now run on a laptop. If you only need a quick spoken version of a document, a browser-based AI text to speech tool will handle it without a subscription.

ElevenLabs

ElevenLabs is the leading system for voice production. Its speech synthesis reaches a level of realism where text becomes audio that genuinely sounds like a person, with a library of preset voices and the ability to clone your own for personalised work.

It is popular with YouTubers, educators and marketers who need professional narration without booking a voice actor for every project. Plans run Free at $0, Starter $6, Creator $22, Pro $99, Scale $299 and Business $990 a month, with Enterprise on request.

AIVA

AIVA — Artificial Intelligence Virtual Artist — targets composers and anyone creating original music. It writes in a range of styles: an orchestral cue for a film, a jingle for a video, a pop track for an advert.

You set mood, tempo and instrumentation and keep creative control, while the AI handles arrangement and harmonisation. It has become a fixture for game developers, filmmakers and indie artists who need to move quickly without losing the thread of their own idea.

Soundraw

Soundraw generates music to a specification. Choose genre, mood and length, and it produces an original track you can customise on the spot.

It is aimed at content owners and offers royalty-free music for YouTube, podcasts and ads, so you can publish without worrying about copyright claims. Ideal if you need fresh music often and have neither a composer's budget nor the patience for library searches.

Voicemod

Voicemod changes your voice in real time. Streamers, gamers and online creators use it for everything from dramatic tones to cartoon voices, with a soundboard for live reactions.

It works for roleplay, podcasts and marketing videos where distinctive audio branding helps content stand out, and it integrates cleanly with streaming software — which is why it took hold in live content specifically.

Murf AI

Murf AI is a professional voice-over tool for businesses, educators and creators, with natural-sounding delivery across many languages and accents. That makes it a fit for training videos, explainers, presentations and e-learning.

Built-in editing lets you sync audio with slides, video or animation without a separate application, which is the practical reason teams standardise on it for volume content production.

How to choose between them without wasting a month

Thirty-five options is a menu, not a shopping list. Work through this in order and you will land on two or three tools rather than a drawer of half-used subscriptions.

1. Name the task, not the category. "Turn our release notes into a two-minute explainer video" narrows the field far faster than "we need AI video". Vague briefs are how teams end up paying for three overlapping tools.
2. Check the product name is current. As this list shows, Ghostwriter became Replit Agent, CodeWhisperer became Amazon Q Developer, and "Copilot X" stopped existing. A guide citing retired names is a guide with stale pricing too.
3. Verify pricing on the vendor's own page. Third-party roundups go out of date within months. Check the tier, the billing period, and whether the price is per user — the per-seat detail is where team budgets quietly triple.
4. Exhaust the free tier first. Nearly every tool here has one. Run your real task, not the demo, and see whether the output survives contact with your actual standards.
5. Test with representative input. Use a real script, a real repository, a real dataset. Models perform very differently on your material than on the vendor's curated example.
6. Check what happens to your data. For code and client material this decides the tool. Tabnine's self-hosting and Amazon Q Pro's IP indemnity exist precisely because this question blocks purchases.
7. Confirm the export path. Can you get your work out in a standard format? A tool that traps output in its own player or project file is a liability once you cancel.
8. Verify before you publish. Every model is confidently wrong sometimes. Run generated text through a checker, validate structured output, and read anything going out under your name.

Frequently asked questions

Are there really 35 tools in this list?

Yes — seven categories with five tools in each: writing, image generation, video, coding, marketing, workplace productivity, and audio and voice. Earlier versions of this page listed Grammarly and ElevenLabs in body text rather than as headed entries, which made the list look two short; both are now listed properly in their categories.

Which of these AI tools have been renamed since 2025?

Two in the coding section. Replit's Ghostwriter is now Replit Agent, and Amazon CodeWhisperer is now Amazon Q Developer. The "GitHub Copilot X" branding was a preview name and no longer appears in GitHub's plans. Model versions have also moved on: Midjourney's site now announces V8.2, ChatGPT's pricing page lists GPT-5.6 variants, and Claude's lineup is Opus 5, Sonnet 5, Haiku 4.5, Fable 5.1 and Mythos.

What is the cheapest way to start using AI seriously?

Stack free tiers. ChatGPT, Claude, GitHub Copilot, Otter.ai, ElevenLabs, Synthesia and Replit all offer one, which covers writing, coding, transcription, voice and video at no cost. Pay only when you hit a limit that is actually costing you time.

Are AI writing tools safe to use for published content?

They are safe as drafting tools and risky as publishing tools. Generated text is fluent whether or not it is accurate, so verify claims against sources, check the facts you cannot personally confirm, and edit for your own voice. Publishing a raw first draft is how factual errors get into print under your byline.

Do I need to disclose that content was made with AI?

Increasingly, yes. Transparency requirements around AI-generated media are tightening, particularly in the EU, and several platforms now require labelling of synthetic media independently of any law. Keeping a simple record of what was generated, by which tool, and who reviewed it is cheap now and expensive to reconstruct later.

Is a paid plan worth it, or is free enough?

For occasional use, free is genuinely enough in most categories. Paid plans buy three things: higher usage limits, access to stronger models, and commercial or privacy terms. If you are billing clients for work produced with a tool, the commercial licence alone usually justifies the subscription.

Bottom line

AI stopped being a trend and became ordinary infrastructure — most of these tools are now doing unglamorous work in the background rather than being demonstrated in meetings. The useful skill is no longer finding tools; it is choosing few and verifying output.

Pick one tool per real bottleneck, exhaust its free tier, confirm its pricing and product name on the vendor's own site, and check what it produces before you ship it. If your bottleneck is social content specifically, our guide to free AI tools for social media campaigns narrows the field further, and the converters you already use will handle the file wrangling in between. A tool earns its place by removing a task you would otherwise do by hand — everything else is a subscription you forgot to cancel.
