Riff
Riff is a free Chrome extension that uses Gemini Nano on the user's computer to draft social-media replies, posts, and direct messages for creators, founders, marketers, and other professionals. On X, LinkedIn, Facebook, and Instagram, users can provide rough notes, adjust tone, and generate a draft tailored to a post or conversation. Riff also helps draft new posts and first messages, and replies to messages in LinkedIn Messaging, Facebook Messenger, and Instagram Direct. Users can configure a personal or brand voice, revise the draft, then insert and send or publish it themselves. Riff runs Gemini Nano locally in desktop Chrome and stores settings and drafts in Chrome storage on the computer. It requires compatible Chrome and hardware plus a one-time model download; it does not send posts on the user's behalf.
