What it is

KIRI Engine is a 3D scanning application that creates models and visualizations using photogrammetry, Neural Surface Reconstruction, and 3D Gaussian Splatting. Photo Scan creates 3D models from photos. LiDAR Scan supports model scans, floor plans, and quick scene visualizations on LiDAR-equipped iOS devices, while Featureless Object Scan is designed for shiny, reflective, transparent, and low-texture objects. The free Basic plan costs nothing and permits up to 150 photos and 2 GB per scan, with unlimited scans and free exports. Pro costs $17.99 a month or $79.99 a year, and raises the limits to 500 photos and 5 GB per scan while adding faster queue processing and advanced scanning and modeling features. The API offers Photo Scan, Featureless Scan, and 3DGS Scan; each API call uses one credit. Credits cost 1.00 USD each, with a 500-credit minimum recharge and 10 free test credits at sign-up. Other listed tools include a website model embedder, a UE5 plug-in, and STL export. Uploaded photos and videos are processed on cloud servers, and local PC scanning is not on the company's roadmap at the moment.
