Riff is a free Chrome extension that helps you reply on X, LinkedIn, Facebook and Instagram.
You paste your rough point. Gemini Nano, the AI built into Chrome, writes a fresh reply for that exact post. You read it, edit it if you want, and press send yourself.
Riff also answers your DMs in LinkedIn Messaging, Messenger on facebook.com and Instagram Direct. When a chat is new, it writes the first message. It can draft your own posts and X threads too: drop in rough notes, ask for changes in plain words, and pick a hook you like.
You set how it sounds. Choose how smart, how salesy and how bold the reply should be. Tell Riff once who you are and how you write, and it follows that voice. Each draft is checked against your recent replies, so it does not repeat itself.
Everything runs on your computer. There is no account, no API key, no server and no monthly bill. Riff never posts or sends anything for you. Install it from the Chrome Web Store: https://chromewebstore.google.com/detail/riff-fresh-replies-and-po/oapafjkedoiikjneaadcdojmophehfhl
