What is Riff?
- Productivity
- Free
- Launched week 43, 2026
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. It also drafts DMs and your own posts, in English or Spanish. Everything runs on your computer with no account, no API key and no server. Riff never posts or sends anything for you.
