AI chat without an account: what still works

Sign-up is where most people get stopped, not the chat itself. The form wants a phone number, the phone number has a country code, and the country code is checked against a list. So the useful question is not "how do I sign up" but "how much can I do without signing up at all".

Logged-out modes on the big providers

Providers have gone back and forth on letting you chat without an account. When it is offered it is real, but it comes with limits worth knowing in advance:

• Shorter memory, sometimes none between messages.
• The older or smaller model, not the one the paid tier gets.
• Tight message caps, and no history you can come back to.
• The same country check. Logged out or not, the request still arrives from somewhere, and an unsupported country is unsupported either way.

That last point catches people out. Skipping the account skips the phone number, not the geography.

Someone else's account, wearing a different name

A whole layer of sites offer "free ChatGPT, no login" by putting their own API key behind a chat box. They work, and they are the worst option on this page for anything you care about:

• Everything you type goes to an operator you cannot identify, on top of going to the model provider.
• They disappear without warning when the key is exhausted or revoked.
• Several are ad wrappers that quietly swap in a cheaper model than the one named on the page.

Fine for a throwaway question. Not for anything with your name, your work, or your documents in it.

Models on your own machine

This is the option that removes the problem instead of routing around it. Open-weight models run locally, with no account, no phone number and no country list, because nothing leaves your machine. Runners like Ollama or llama.cpp make it a single download.

The trade is honest and it is not small:

• You need the hardware. A model worth using wants real memory, and a GPU changes it from slow to usable.
• The small models you can actually run are noticeably weaker than the hosted ones at long reasoning and at code.
• No browsing, no tools, no up-to-date knowledge unless you wire that up yourself.

For drafting, summarising, translating and rewriting, a local model is genuinely enough. For the work people pay for the hosted models to do, it is not, and pretending otherwise wastes a weekend.

If none of that fits

Then you are back to the access question, and it is worth being precise about which kind you have: where ChatGPT is unavailable, and why splits the two cases and says what each one actually costs to solve.
