Read full description

3D AR Model Viewer is a 3D studio that fits in your pocket: open a model, create one, and stand it in your room at its real size. OPEN YOUR OWN FILES Import USDZ and Reality files for free, keep them in a personal library, and inspect them in 3D. No account, no payment. CREATE FROM AN IDEA OR A PHOTO Describe an object or pick a photo, and get a 3D model back. Style presets suggest a direction; they are inspiration, not a guaranteed result. AI output varies with the input. THOUSANDS OF FREE MODELS Browse a large community catalog β€” furniture, characters, animals, vehicles, architecture. Every model shows its author and its license. CHECK REAL SIZE Enter the dimensions you were given and compare the object with the space you have. Try a free size ghost, or pick a furniture stand-in. A fit check compares the numbers you supply and AR helps you picture them; it does not replace a tape measure. FROM SCREEN TO ROOM OR PRINTER Place a model in your room with Apple's AR Quick Look, then record and share the session. Export a model you generated: the file it already is comes out free, and converting it to GLB, USDZ, STL, 3MF or OBJ costs one credit per conversion, with the print height you choose for STL. A FREE WAY IN Importing your own files, browsing the catalog, viewing in 3D and placing in AR are free. AI generation uses credits: buy a small pack when you need one, or choose Pro for regular creation. AR requires a compatible device. PRO INCLUDES β€’ 30 generation credits every month β€’ AR recordings with no watermark β€’ Priority support Unused monthly credits reset each month; credits bought in a pack stay available. SUBSCRIPTION DETAILS Pro Monthly is an auto-renewing monthly subscription. The App Store shows your local price before purchase. Payment is charged to your Apple Account at confirmation. The subscription renews automatically unless it is cancelled at least 24 hours before the end of the current period; renewal is charged within 24 hours before the period ends. Manage or cancel your subscription in your Apple Account settings. Model catalog powered by the Sketchfab community.
