FAQ
How Does It Work?

Is RewriteBar Safe?

How your text is processed depends on the provider you choose: RewriteBar (default): Your selected text is sent to the RewriteBar server, which forwards the request to a language model and returns the corrected version. We do not store your text or API key on our server. Third-Party Providers (e.g. OpenAI, Mistral, Ollama): Your request is sent directly from your device to the providerās API.
