🔐 Privacy
Your API keys are stored only in chrome.storage.local on your device and are sent only to the provider you choose. Nothing goes to a Briefly server — there is no Briefly server.

👤 Built for writers, students, developers, researchers, language learners, and anyone who wants to dictate, listen, or translate without leaving the browser.

Tips when pasting:
- Chrome Web Store allows light Markdown — bold works, headings don't. The asterisks above will render as bold.
- Stays well under the 16,000 char limit (~1,400 chars).
- Lead line is keyword-rich for search: voice to text, text to voice, Chrome.
