About Riff

Riff is a free Chrome extension that turns your rough point into a fresh reply for any post on X, LinkedIn, Facebook or Instagram. It uses Gemini Nano, the AI built into Chrome, so it runs on your computer with no account and no API key. It also answers DMs and drafts your own posts, and it never posts or sends for you.
