Lifarium is a free tool which can help view any Opensea NFT in Augmented Reality. Just copy paste any Opensea NFT link in the lifarium app and get started:
Points to note:
1. Works with images and 3D models for now
2. Works best in AR supported phones
3. Safari in iOS and Chrome in Android best
4. 3D models with animations will be shown without animations
5. Complex 3D models will not be rendered correctly
6. Forgive me if you see any bugs, made the whole thing myself learning a lot of new things.
