Sherlock is a reverse image search and AI photo checker. Drop in a photo and Sherlock shows you where that image already appears online, whether it looks AI-generated, and what's in it — so you can check a picture before you trust it. WHY SHERLOCK A photo can be borrowed, resold, or generated. Before you act on one, it's worth knowing whether it has been somewhere else first. WHAT YOU CAN DO • Reverse Image Search — find the public pages and sites where the same picture already appears. • Spot AI-Generated Photos — get a score for how likely a picture was made by AI. • Identify What's in the Photo — get a plain description of the object shown. • Keep Your Results — past checks are saved on your device, and only there. HOW IT WORKS 1. Pick a photo, take one, or paste an image address. 2. Sherlock runs a reverse image search and an AI-generation check. 3. You get a report: where the image appears, how AI-likely it looks, and what it shows. GOOD FOR • A listing photo that looks too good for the price. • A picture someone sent you that feels off. • Checking whether an image is a real photo or AI output. • Finding pages that are using a photo of your own. WHOLE-IMAGE SEARCH, NOT FACE RECOGNITION Sherlock matches the whole picture. It is not facial recognition. It does not detect, scan, or map faces, and it never creates or stores biometric data. It finds public web pages where the same image already appears. PRIVACY • Photos are uploaded over an encrypted connection only to run your check, then deleted from our servers right after — never used to train AI. • Your search history stays on your device. Turn it off or clear it anytime in Settings. • No name or email needed to get started. • Before your first check, Sherlock names every service your photo is sent to. AI NOTICE Reports are generated automatically and can be incomplete or inaccurate. Sherlock gives you signals, not verdicts — always verify before acting. FREE & PREMIUM Start with a free check each day. Premium unlocks unlimited checks and full reports. Subscriptions renew automatically unless canceled; manage anytime in your App Store account.
