Question 1

How does LegoFinder identify LEGO sets from photos?

Accepted Answer

LegoFinder uses large multimodal AI models (similar to the technology behind ChatGPT's image understanding) to analyze your photo. The AI examines brick colors, shapes, printed elements, minifigure details, and overall structure, then cross-references these visual features against known LEGO sets. When it's confident, it shows an immediate match. When multiple sets look similar, it shows the top candidates so you can pick the right one.

Question 2

Is LegoFinder free?

Accepted Answer

Yes, completely. There is no sign-up, no subscription, no per-use fee, and no hidden costs. The site is supported by advertising. You can upload photos, search sets, browse themes, and read guides — all for free.

Question 3

What photo formats and sizes work?

Accepted Answer

LegoFinder accepts JPG, JPEG, PNG, WEBP, and HEIC images. There is no strict size limit, but very large files may take longer to process. For best results, use a clear, well-lit photo taken in natural light with the LEGO set as the main subject against a plain background. Avoid extreme close-ups — try to capture the full set or a recognizable section.

Question 4

Can it identify partially built sets?

Accepted Answer

Yes. The AI can recognize LEGO sets that are partially assembled, fully built, still in the box, or even from a photo of the instruction booklet cover. The more complete and visible the set is, the higher the accuracy. A section showing 30-40% of a distinctive set is usually enough for a correct identification.

Question 5

What if the AI gets it wrong?

Accepted Answer

AI identification is highly accurate but not perfect. If the result looks wrong: (1) Try a different angle with better lighting. (2) Include more of the set in the frame. (3) Check if the AI offered alternative matches below the top result. (4) For very similar sets (like different versions of the Millennium Falcon), verify by checking the set number printed on your original box or instruction booklet.

Question 6

Can it identify individual LEGO pieces?

Accepted Answer

Yes. Use the 'Identify Parts' tool to photograph a single LEGO brick or element. The AI returns the part number, official color name, element category, and links to find it on BrickLink and Rebrickable. This works best with distinctive or unique pieces — common 2x4 bricks may return generic results.
