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.

Riff also answers your DMs in LinkedIn Messaging, Messenger on facebook.com and Instagram Direct. It can draft your own posts too.

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.
