Riff

Riff overview

Riff is a Chrome extension for drafting replies, comments, DMs, first messages and social posts on X, LinkedIn, Facebook and Instagram. It uses Gemini Nano in Chrome to write on your computer, and you review and send each draft yourself. You can adjust tone, length and other writing options, save brand voices and presets, and adapt a post for another platform. Riff says your saved content stays in Chrome storage on your computer; it requires a one-time model download and does not need an account or API key.
