Sherlock Search reverse image search is a web-based tool for checking where a face may appear across publicly indexed websites. Users upload one clear photo, compare possible visual matches, and review the original pages to investigate online identities, reused profile photos, or potential impersonation. It is designed for responsible public-web research without requiring an account. The service accepts JPG, PNG, and WebP images up to 10 MB and guides users through face framing, access confirmation, photo confirmation, and source review. Its visual matching workflow provides confidence bands for possible results, links to public profiles, posts, and indexed images, and supports source verification across sites such as Instagram, TikTok, YouTube, Facebook, LinkedIn, Pinterest, Telegram, and dating platforms. Users can compare names, dates, captions, account history, and other context before drawing conclusions. Sherlock Search helps users move from a thumbnail or similarity score to the public source behind a possible match. It does not access private profiles or hidden databases, and results are leads rather than proof of identity, ownership, intent, or wrongdoing. The service is currently free, requires no card or subscription, and retains search media for up to 24 hours.
SightRadar is a high-accuracy face recognition API built as a drop-in replacement for AWS Rekognition. It uses the same request and response shapes (CreateCollection, IndexFaces, SearchFacesByImage, CompareFaces, DetectFaces), so you migrate by changing the endpoint URL. Find a person across thousands of photos from one selfie, run 1:1 verification with your own similarity threshold, or detect faces with confidence scores. Billing is per photo, never per face, with no subscription or minimums.
iPhone safety timer for runs, hikes and dates (iOS 26+). A missed check-in can trigger an SMS attempt to your primary contact after server confirmation. Delivery needs SMS credit, service and mobile networks. Subscription required; location sharing is optional. Does not replace emergency services.
