Turn a rough point into a fresh reply for any post on X, LinkedIn, Facebook or Instagram, written by Chrome's built-in AI on your computer.
Details
What it does
Riff is a free Chrome extension. 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 on facebook.com and Instagram Direct, and drafts your own posts from rough notes. Everything runs on your computer: no account, no API key, no servers and no monthly bill. Riff never posts or sends anything for you.
Ideal for
- Founders who reply on X and LinkedIn
