- ChatGPT, Claude, Gemini, Perplexity, and NotebookLM all accept email or Google signup; no card anywhere in the flow.
- 'Free tier' and 'free trial' are not the same thing: trials want the card now and end later.
- If you want no account at all, a local model (Ollama or LM Studio) runs offline on your own computer.
You don't need a credit card to start with serious AI. ChatGPT, Claude, Gemini, Perplexity, and NotebookLM all have free tiers that accept a plain email or Google account. The card is only required on the 'trial' tiers, which are a different animal entirely.
A free tier is permanent and asks for nothing but an email. A free trial is temporary and asks for the card up front. Skip anything with the word 'trial' if all you want is free access.
| Tool | Signup | What the free tier gives you |
|---|---|---|
| ChatGPT | Email or Google | Latest model, file uploads, general chat |
| Claude | Email or Google | Long documents, careful writing, 1MB context |
| Gemini | Google account | Fast answers, generous quota, mobile app |
| Perplexity | Email or Google | Answers with cited sources |
| NotebookLM | Google account | Q&A grounded in documents you upload |
| Microsoft Copilot | Microsoft account | Browser and Windows integration |
| Mistral Le Chat | Email or Google | Practical European-made assistant |
| Hugging Face Chat | Open-source models, tinkerable | |
| Ollama (local) | No account | Open models running on your own machine |
| LM Studio (local) | No account | Offline drafting with local models |
Your first ten minutes, card-free
- Pick one general chatbot (ChatGPT or Gemini) and sign up with email.
- Add NotebookLM for anything document-heavy (terms, manuals, research PDFs).
- Add Perplexity when you need sources you can click.
- Skip every upsell screen; all three have usable free tiers.
The one real card-free loophole
For truly unlimited, no-account use, run a model locally. Ollama and LM Studio download open-source models onto your computer, and the only limit is your hardware. It takes a bit of setup and a decent machine, but nothing you type ever leaves it, and nothing ever expires.
Reading the fine print before you pay
- Check the pricing page's 'Free' row; it should not mention a card.
- Look for a note about message caps or peak-speed throttling.
- If a button says 'Start trial,' treat the card field as a deposit, not a formality.

Free AI is genuinely free if you only tell the sites where not to put the card.
FAQ
Frequently asked questions
Which AI tools are truly free without a credit card?
ChatGPT, Claude (on the web), Gemini, Perplexity, NotebookLM, Microsoft Copilot, and the basic tiers of most other big chatbots all accept plain email or Google signup. Desktop models like Ollama's Llama builds or Mistral run locally and never ask for an account at all.
Why do some AI sites ask for card details on signup?
Those are usually free trials, not free tiers. A real free tier says 'free' in the signup flow and lets you through with a password. A trial says 'start trial' and stores the card for when it ends. Check the pricing page before you hand anything over.
What's the catch with free AI tiers?
Usage limits and slower peak speeds. Providers meter compute, so free accounts get fewer messages or longer waits. That's usually fine for real work, and if you hit limits often, that's the signal to consider paying.
