Free AI

AI tools you can use without paying

Two very different realities hide behind the word “free.” We separate them, because finding out the limit after three days has never made anyone happy.

What “free” means

Tools whose pricing we haven't yet verified on the publisher's page don't appear here, even if they probably have a free version. See the full ranking.

Truly free
Free software or a service with no paid tier. Often something you install yourself, which has one advantage: your files never leave your premises.
Free tier
Most of the market. Genuinely usable, but capped: number of requests, export quality, or features reserved for paying users.
“Unlimited” doesn't exist
A model costs money on every request. A service that promises free and unlimited makes its money elsewhere: advertising, reselling data, or reusing what you send it. For client data, that's a dealbreaker.
