Our verdict

GPTs Extension is a Chrome-based directory for browsing and sharing custom GPTs, pulling its listings from bestgpts.app rather than being an official OpenAI product. Verified builders can earn money from user engagement with the GPTs they list, so there's a monetization angle alongside plain discovery. It has no ratings yet, and there's no detail anywhere on how search or verification actually works.
