❓ Quick FAQ

Does this use AI to process text?

No cloud AI processing. Core cleanup is rules-based. Optional grammar checking uses a browser-based WebAssembly asset.

Is my text private?

Mostly local by design. Core cleaning happens in your browser. Optional grammar checking may load a browser-based grammar asset when enabled.

Can I use this commercially?

Yes! Free for any purpose. JSON export great for app integration.

How effective is it?

Useful as a review aid. It catches many common grammar, hidden-character, AI-style, and prompt/script risk patterns, but no automated checker catches every issue. Review important text and security findings before relying on them.
