Riff is a free Chrome extension for replying on X, LinkedIn, Facebook and Instagram. You paste your rough point, and Gemini Nano, the AI built into Chrome, writes a fresh reply for that post. You read it, edit it and press send yourself. It also drafts replies to direct messages on LinkedIn, Facebook Messenger and Instagram, and drafts your own posts. Everything runs on your computer, with no account, API key, server or monthly bill.
Key features
- Writes a reply to a post on X, LinkedIn, Facebook or Instagram from your rough point
- Drafts replies to direct messages on LinkedIn Messaging, Messenger on facebook.com and Instagram Direct
- Drafts your own posts and first messages
- Runs on-device with Chrome's built-in Gemini Nano, with no server or API key
- Never sends anything: it fills the box and you press send
What stands out
- Free, with no account or subscription
- Your voice, drafts and history stay in Chrome storage on your computer
- It never posts or sends for you, so every message is yours
Trade-offs
- Needs desktop Chrome 138 or newer and a one-time download of about 4 GB for the on-device model
- Drafts come from a local model and may need rewriting
- Not supported on messenger.com, and the page gives no one-time price or compliance guarantee

The page says there is no account, no subscription and no monthly bill, and gives no price. It requires desktop Chrome 138 or newer on Windows, Mac, Linux or Chromebook Plus; older versions support English, Spanish and Japanese on-device and newer ones add French and German. The maker is Zima Media OU, Tallinn, Estonia (founder Michael Zima), and Riff is not affiliated with Google, X, LinkedIn or Meta. The page says Riff is designed to stay within platform automation rules by never sending for you, which is not a guarantee.
