Offo is a web-based directory and weekly leaderboard for AI tools. It tracks new AI product launches and ranks them by community votes. The site allows visitors to explore current and past launches, search by task, and browse categories such as writing, image, video, voice, code, and productivity. The directory contains over 18,000 tools. Each weekly cycle runs from a specified date range and is ranked by community upvotes. Voting is limited to one vote per person per product and closes Monday at 00:00 UTC. Users can discover what makers are building, view featured tools, and review the previous week's best results. Offo also serves as a launch platform for makers. To list a tool, a user pastes a public website URL, reviews and edits the generated draft, and publishes the listing for free. Makers can choose a launch week for their own tool, making the platform useful both for discovering new AI products and for introducing new ones to a broader audience.
