FAQ

Does it work everywhere?

Most sites and editors, yes. Browser-restricted pages (e.g., chrome://, the web store, PDFs) don’t allow content scripts. Use the popup input there.

Can I change the shortcut?

Yep — go to chrome://extensions/shortcuts and set your own key for “Improve selection.”

How are API keys stored?

Keys live in your browser’s local storage. Fluentify has no servers and sends your text directly to the provider you choose.
