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, and it can draft your own posts. You set how it sounds: how smart, how salesy and how bold. 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.
