About Riff
Riff is a free Chrome extension that helps you reply on X, LinkedIn, Facebook and Instagram. You paste your rough point. Gemini Nano, the AI built into Chrome, writes a fresh reply for that exact post. You read it, edit it if you want, and press send yourself. It also answers DMs and drafts your own posts. Everything runs on your computer. There is no account, no API key, no server and no monthly bill. Riff never posts or sends anything for you.
Riff launched on Founder.best on Dec 28, 2026 by Hyperpage and is listed under AI Writing.
