What is Riff?
Riff is a Chrome extension that helps you reply to posts, answer DMs, and draft your own posts across X, LinkedIn, Facebook, and Instagram. You give it your point, then it turns that rough idea into a fresh message that fits the exact post or conversation. It runs in Chrome’s side panel and works right where you are, so you can read, tweak, and send without switching tools. It also uses Gemini Nano built into Chrome, so it works on your computer without servers, API keys, or monthly bills. You can choose the tone, make it shorter or punchier, and repurpose one draft into different formats for multiple sites.
