Where it all started

From a Twitter bot to a full reverse image search platform.

SearchThisImage began as @SearchThisImage — a Twitter bot that helped users verify images by conducting reverse image searches directly on the platform. With over 30,000 followers, it became a trusted tool for journalists, fact-checkers, and everyday users fighting misinformation. Now, that same technology is available as an API and OpenClaw skill for anyone to integrate into their applications and workflows.
