✨6 models, free to use, no credit card

Many models. One window.

Ask a question, switch models mid-conversation, and find any thread again later. When a model is rate-limited, niato ai moves to the next one instead of failing on you.

What niato ai does

A plain chat interface built around open models you can use for free.

Several models

6 Google Gemini models, sorted from the most economical to the most capable. Switch between them at any point, even mid-conversation.

Automatic failover

When a free model hits its rate limit, the reply restarts on the next model in the list instead of returning an error.

Searchable history

Conversations are saved, grouped by date, and searchable by title or by the content of their messages.

6 tones

A selector changes how the assistant answers, from steady and factual to playful, without rewriting your instructions each time.

Code and formulas

Syntax highlighting, LaTeX math and Markdown tables are rendered directly inside the answers.

Protected account

Sign in by email with verification, or through Google and GitHub. Your conversations are readable only from your own account.

Available models

All reachable as soon as your account exists, at no cost to you.

Frequently asked questions

Is it really free?

Yes, for you. There is no card to enter and no trial countdown. Model usage is paid for by the project, which is why the catalogue favours efficient models. The Enterprise plan exists for organisations that need a contract, not to unlock features.

What happens when a model is rate-limited?

Models have throughput limits set by their provider. When one is reached, niato ai restarts the reply on the next model in the list and tells you it switched.

Are my conversations kept?

Yes, they are saved to your account so you can find and search them later. You can delete any conversation from the sidebar at any time.

Can I change model mid-conversation?

Yes. The model selector sits under the composer, and the change applies to your next message without clearing the history.
