Demo & limits
Every check sends your image to a frontier vision model, and that costs real money per request. Rather than charge for it or wrap it in ads, Clairfy runs as a free demo under limits that are stated up front and enforced on the server.

Common questions
Yes. There's no paid tier, no trial, and nothing to cancel. The only thing an account gets you is a saved history of your own checks.
Clairfy is a portfolio project, not a business, and it runs on a cloud account shared with other work. An uncapped public endpoint calling a paid model is an unbounded bill, so the ceiling is enforced in the application itself.
New images stop being analyzed until the cap resets, and the app tells you that's what happened instead of showing an error. Images that have already been checked still return instantly from cache, because serving those costs nothing.
It did — an ad-gated free tier and a $10/month subscription, both built and shipped. When the project wound down they were switched off rather than deleted; the billing and ad code is still in the repository behind a feature flag.
