Nosso top 3 de assistentes de IA

The first two are close. ChatGPT and Gemini both offer chat, image generation, voice and research on a free plan, on the same devices. ChatGPT comes first because it is general-purpose, where Gemini is tied into Google's apps, and its app has about 11 million ratings against 2.3 million. Gemini costs less to upgrade, from $4.99 a month. Microsoft Copilot is third for people who work in Word, Excel and Outlook. Claude narrowly missed: it is aimed at writing, analysis and coding and adds a Linux app, but its lowest paid plan costs more than any of the three.

  1. 1º lugar: ChatGPT

    Plano gratuito · a partir de $8/mês

    Para: Most people

    ChatGPT puts text chat, image generation, spoken conversations, web search and research reports in one assistant, on the web, Mac, Windows, iPhone and Android. The Free plan allows unlimited text chats, and paid plans start with Go at $8 a month. Plus, at $20 a month, adds advanced reasoning models, projects and the Codex coding agent. Its iPhone and iPad app averages 4.8 from about 11 million ratings. Know the limits: the Free plan limits uploads, image creation, voice chats, deep research and memory, OpenAI says the Go plan may include ads, and Pro costs $100, $200 or $500 a month.

  2. 2º lugar: Gemini

    Plano gratuito · a partir de $4.99/mês

    Para: People who already use Gmail, Docs and Google Drive

    Gemini is free with a Google Account, and the free plan includes image generation, Deep Research and spoken conversations through Gemini Live. It works with Gmail, Drive, Docs and Calendar and runs on the web, Mac, Windows, iPhone and Android. Google AI Plus is $4.99 a month with 400 GB of storage, less than ChatGPT's lowest paid plan. Its iPhone and iPad app averages 4.7 from about 2.3 million ratings. It is second because it is tied into Google's apps and plans: paid tiers are Google AI plans that bundle storage and other Google services, with no Gemini-only plan listed, and features vary by region. The macOS app needs Apple Silicon and macOS Sequoia (15.0) or later.

  3. 3º lugar: Microsoft Copilot

    Plano gratuito · a partir de $9.99/mês

    Para: People who work in Word, Excel, PowerPoint and Outlook

    Microsoft Copilot covers chat, answers grounded in web search, image creation and voice conversations, on the web, Windows, Mac, iPhone and Android. Paid Microsoft 365 plans put it inside Word, Excel, PowerPoint and Outlook: Personal is $9.99 a month or $99.99 a year and includes 1 TB of cloud storage. It is third because its free version is limited and subject to available capacity, with usage limits the pricing page does not give, and its Researcher and Analyst agents need Premium at $19.99 a month, where Gemini includes Deep Research free. On the Family plan the AI features are for the subscription owner only.

Você conseguiria criar a sua?

There is no plain version of an AI assistant. The model is the product. You can rent one by the request and put a chat box in front of it, and then you are paying for every answer.
