How can they be free and unlimited?
Regular online tools upload your files to their servers, and every minute of audio or video costs them money. That's why they cap daily use, add watermarks or ask for a subscription. These tools work differently: your own browser does the work, using WebAssembly, WebGPU, WebCodecs and open-source AI models that download once. We don't pay per use, so we can keep them free and unlimited. The site is supported by ads.
Privacy by design

FAQ
Do I need to install anything or create an account?
No. You only need an up-to-date browser on a computer or phone.
Why is the first run slower?
AI tools download their model the first time you use them. It stays cached in your browser, so later runs start almost instantly.
