Riff is a free Chrome extension that helps you reply on X, LinkedIn, Facebook and Instagram. You paste your rough point and Gemini Nano, the AI built into Chrome, writes a fresh reply for that exact post. You read it, edit it, and press send yourself.
It also answers DMs in LinkedIn Messaging, Messenger and Instagram Direct, drafts your own posts and X threads, and learns your voice. Everything runs on your computer: no account, no API key, no servers.
