LEGO Set Identifier Pro

Explore possible LEGO set matches and keep notes about your own builds.

START WITH YOUR PHOTO
Take a photo or choose one you already have. Add up to three views, check the details and request an AI-assisted possible match. Review the suggested identity and visible clues before confirming a record yourself.

KEEP YOUR OWN BUILD COLLECTION
Save photos, dates, notes and favourites. Add the details that matter to this subject: Set number, Theme, Pieces owned, Missing pieces. Search your records, edit them as you learn more and delete them whenever you choose.

COMPARE AND LEARN
Browse a small, bundled starting reference library, save useful references and compare up to three entries side by side. Use the photo and observation guides to capture clearer details. The reference library is a starting point, not an exhaustive catalogue.

TOOLS FOR YOUR HOBBY
Use the build progress alongside your collection. Keep a separate journal for observations and questions you want to revisit.

YOUR RECORDS STAY WITH YOU
No account is required. Saved records, photos, favourites and journal notes stay on your device. Export a complete JSON backup, restore a compatible backup or export your records as CSV. Choose reduced motion for gentler transitions.

PHOTO IDENTIFICATION NEEDS INTERNET
Only the photos you choose to identify are sent through our Cloudflare service to OpenRouter and its AI providers. Device identifiers and limited request metadata support security and service usage controls. Offline collection and reference features remain available without a connection. AI identification is subject to availability and fair-use controls; purchasing the app does not provide unlimited requests.
