About Riff
Riff is a free Chrome extension that drafts social media replies, posts and DMs on X, LinkedIn, Facebook and Instagram. Drafts are written on-device with Chrome's built-in Gemini Nano, so nothing leaves your device. No account and no API key.
Why Riff
01 · The problem
Writing a fresh, fitting response to every social post takes time and effort, and generic replies rarely land well.
02 · The solution
Riff turns a rough point into a reply, DM, post or first message tailored to the specific post or conversation, using AI that runs locally in Chrome and leaves sending to you.
03 · What makes it different
Riff runs Gemini Nano on your computer with no servers, API keys or monthly bill, and it never posts or sends for you.
Who it’s for
Social media users who write replies, DMs and posts on X, LinkedIn, Facebook and Instagram.
