Fresh replies for every post, written on your computer
About Riff
Riff is a free Chrome extension that helps you reply on X, LinkedIn, Facebook and Instagram. Paste your rough point and Gemini Nano, the AI built into Chrome, writes a fresh reply for that post. It also answers DMs and drafts your own posts. It runs on your computer with no account and no API key, and no text is sent to servers. It never posts or sends for you.
