About

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, and drafts your own posts. Everything runs on your computer. There is no account, no API key, no server and no monthly bill. Install: https://chromewebstore.google.com/detail/riff-fresh-replies-and-po/oapafjkedoiikjneaadcdojmophehfhl
