Where ChatGPT is stronger

  • Price for one person. Go at $8 and Plus at $20 cost less than Starter at €39. If you work alone and OpenAI's models are all you need, ChatGPT is the cheaper choice, and we'd tell you the same on a call.
  • OpenAI's latest models and features. Plus includes OpenAI's advanced reasoning models and early access to new features, and Pro adds research previews.
  • Agents and coding. ChatGPT Work takes on multi-step tasks, Codex works on codebases, and Pro adds Dot, an always-on agent. Infinithink doesn't sell self-service agents.
  • Everyday extras. Voice with video, memory across chats, deep research, scheduled tasks, Sites and an app directory.
  • Native apps. ChatGPT runs on the web, desktop and mobile. Infinithink runs in your browser.
  • Company controls. ChatGPT Business includes SSO and multi-factor authentication and, according to OpenAI, doesn't train on business data by default. Enterprise adds SCIM, role-based access controls and data residency.

Where Infinithink is different

  • The leading AI models, one workspace. Different models write differently, and the only way to know is to try the same brief on both. In our all-in-one AI assistant you switch models from the same screen and keep one subscription, with GPT, Claude and Gemini depending on your plan. Read the AI model comparison for what each one is good at.
  • Writing that sounds like your business. Templates turn your most common jobs into a form, so a product description, a newsletter or a LinkedIn post starts from a structure instead of a blank prompt. Save your Brand Voice once, with a few samples of your best writing, and use it across templates. You can also build your own templates for the work only your business does.
  • One price for the team. Business includes 10 seats for €199 a month, and you don't add a seat each time someone joins, up to ten people. For ten people, ChatGPT Business Standard seats cost $250 a month billed monthly (about €222), or $200 a month billed yearly (about €178). The plans aren't identical: ChatGPT Business includes agents, Codex and admin controls that Infinithink doesn't offer, and the 10 Infinithink seats share one pool of 55,000 credits a month, while each ChatGPT seat comes with its own usage.
  • Not a ChatGPT wrapper. Infinithink connects to models from several providers through their business APIs and builds the workspace around them, with templates, Brand Voice, documents, images, voice and team seats. ChatGPT is one product from one provider. Infinithink is a place to use several.

Who should stay on ChatGPT, and who should try Infinithink

ChatGPT is a strong general assistant, and for many people it's the right tool. Infinithink does a narrower job. It's built for businesses that produce content every week and want more than one model provider, ready-made templates and shared seats, on one bill in euros. If that sounds like your team, read on. If it doesn't, staying where you are may be the right call.

  • You work alone, mostly by voice or on your phone, or depend on OpenAI's own tools

    Pick ChatGPT

    ChatGPT is the better fit if you want the most for $20 a month, talk to it by voice or video, depend on Projects, scheduled tasks, custom GPTs, apps or deep research, want OpenAI's agent features such as ChatGPT Work, Codex or Dot on Pro, or your company needs an admin console with SSO or Enterprise controls such as SCIM and data residency.

  • Several people write for one brand every week

    Pick Infinithink

    Infinithink is the better fit if you want to compare drafts from different model families without paying for three subscriptions, would rather pick a template than rewrite a prompt, need several people to sound like one company, are a team of up to 10 that prefers one fixed price to per-seat billing, want prices in euros and support in English or Italian.

Frequently asked questions

Which ChatGPT alternative is right for a small business?

Start from how you work. If one person uses AI for questions and quick drafts, ChatGPT Plus is hard to beat on price. If several people write content for the same brand and want more than one model, a business workspace like Infinithink fits better, with specialized writing tools, Brand Voice and 10 seats on Business for €199 a month.

Is there a free ChatGPT alternative?

Yes. Infinithink has a Free plan with no time limit, with 150 credits a month, Claude Sonnet 5.5 and the standard GPT models, 130+ specialized writing tools and 3 AI images a month. No credit card required. Gemini comes with the paid plans from Lite, GPT-6 Sol from Starter.

Is Infinithink cheaper than ChatGPT Plus?

Not like for like. Plus costs $20 a month (about €18) and Starter, with Claude, GPT and Gemini, costs €39. Our Lite plan costs €12 with Claude Sonnet 5.5 and the standard models. For teams the comparison changes, because Business costs €199 a month for 10 seats, while ChatGPT Business costs $25 per seat a month, or $20 billed yearly.

Is Infinithink just a ChatGPT wrapper?

No. Infinithink uses models from OpenAI, Anthropic and Google through their business APIs, depending on your plan, and adds the tools a business needs around them, like templates, Brand Voice, chat with files, images, voice and team seats.

Can I use Claude and Gemini without separate subscriptions?

Yes. From Starter, GPT, Claude and Gemini are included in the same workspace and on the same bill. Business adds the top-tier models.

How do I switch from ChatGPT?

Export your history from ChatGPT (Settings, Data controls, Export data) and keep it as an archive, because Infinithink doesn't import ChatGPT chats. Turn the ten prompts you reuse most into custom templates, set up your Brand Voice with two or three pieces of writing you're proud of, and upload the files you keep re-sharing. Start on the Free plan, run both tools on real work for a few weeks, and cancel ChatGPT when you're ready.

Do I need my own OpenAI or Anthropic API key?

No. AI credits are included in every plan, so you don't need an account with any model provider.

Is my data used to train AI models?

Your text and files go to the provider of the model you choose, which generates the answer. We use these providers through their paid business APIs, whose terms exclude using that data to train their models, and we don't use your content to train AI models. The details are in our legal information. For ChatGPT, OpenAI says individual plans let you opt out of training, and Business data isn't used for training by default.
