Best alternatives to Sherlock in 2026
Anyone who has swapped messages with someone on a dating app, a rental listing, or a marketplace has probably wondered at some point whether the person's photo is actually them. Doing a proper reverse image search on a phone is normally awkward — most tools are built for desktop browsers, and screenshotting a chat photo to search it is clunky. Sherlock is built specifically to work well on a phone: it runs entirely in the mobile browser, resizes the photo locally before uploading, and searches the web for other places that same image appears. Beyond basic reverse search, it includes AI-detection to flag generated or edited photos, checks for known impostor-account patterns, and offers plugins for common contexts — dating apps, rental listings, resale marketplaces. It keeps search history stored only in the browser rather than on a server, and supports several languages beyond English (Spanish, Portuguese, German, French, Japanese). The free tier allows one search per day; beyond that it's pay-as-you-go credits (50 for $9.99, up to 500 for $49.99, credits don't expire) or a subscription ($9.99/week or $69.99/year) with weekly credit refills.
