AI & Generative AI

Riff is a free extension for Chrome, Brave and Edge. Chat in its dedicated tab, Riff Home, and write replies and posts in a side panel on X, LinkedIn, Threads, Facebook, Instagram, YouTube, and on the web versions of Slack and Teams. All models run on your computer, and Riff never posts for you. No server, no API key, no monthly fee. Gemini Nano writes in 5 languages, Gemma 4 in 16.
