Description

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 answers DMs in LinkedIn Messaging, Messenger on facebook.com and Instagram Direct, and drafts your own posts. Everything runs on your computer: no account, no API key, no servers. Riff never posts or sends for you.

Why try Riff?

The problem: Replying to posts and DMs on social sites takes time and often starts from a blank box.

Built for: People who reply a lot on X, LinkedIn, Facebook and Instagram
