Kiri Engine: cost, fit and limits
Kiri Engine is a 3D scanning app and web service from KIRI Innovation that turns phone photos and LiDAR captures into textured models, with Gaussian splatting and AI-generated materials on its paid tier. It runs as mobile apps and a web app.
What to know first
Kiri Engine offers a free Basic tier and a Yearly Pro plan at USD 79.99 billed yearly, equal to USD 6.66 a month. Basic allows Photo Scan up to 150 photos and 2 GB per scan with 4K textures, while Pro raises photo counts, adds 8K textures, Gaussian splatting, AI-generated PBR materials and auto rigging. The page shows no monthly Pro price and no credit pack prices.

Who Kiri Engine is best for
Game and animation artists
Yearly Pro adds PBR material generation with AI, automatic rig generation, quad mesh generation and 8K textures, features aimed at asset preparation.
Makers who print scanned objects
Basic exports OBJ, FBX, STL and GLB and offers unlimited LiDAR scans, so a 3D printing workflow starts without a subscription.
Casual testers of phone scanning
The free tier includes in-app cropping, texturing, measurement and web app access, enough to judge scan quality before paying. Nothing is locked behind a card for those first tests.

What Kiri Engine does
- Photo Scan with tiered limits
- Basic allows up to 150 photos per scan and Yearly Pro up to 500 on advanced export, so larger objects need the paid plan. Pricing pages list the limits by tier, so check which one covers your largest scan.
- Gaussian splatting
- The 3DGS Scan with Mesh option works with up to 300 photos on Yearly Pro, adding splat-based capture next to mesh output. Basic does not include Gaussian splatting, which is reserved for the paid tier.
- AI-generated PBR materials
- Yearly Pro can generate PBR materials with AI, which saves manual texture work when an asset heads to a game engine or renderer. The page gives no detail on the model behind this feature, so test outputs before relying on them.
- Auto rig generation
- Pro generates rigs automatically for animation and motion capture, a feature that most survey-oriented tools in this group do not list. It is listed as a Pro feature next to quad mesh generation and file format conversion.
- LiDAR capture
- Room, scene and object scans with LiDAR are available on both tiers, so the free plan covers sensor-based capture without photo caps. Photo scans, by contrast, stop at 150 photos on Basic, so LiDAR owners get more from the free plan.
How Kiri Engine handles your data
The privacy policy names KIRI Innovation and does not say whether customer content trains AI models or how long data is retained. The FAQ says data is stored and processed on KIRI cloud servers, without naming a region, and that deleting an account removes data permanently. No certification appears in the policy. Because processing runs through the vendor's cloud, scans of private property or client sites travel off your device, so the vendor's policy was not checked for AI training or residency beyond these statements.
Where Kiri Engine falls short in practice
- Photo and size caps on Basic. Basic stops at 150 photos and 2 GB per scan, and Gaussian splatting, 8K textures and the AI features all need Yearly Pro. Larger objects and room-scale photo scans therefore need the paid plan to complete.
- Pricing gaps. No monthly Pro price appears on the pricing page opened, and credit packs and in-app purchase prices are not published, so total cost is unclear.
- Contradictory renewal wording. The Basic card says it renews at USD 79.99 a year after a trial while also showing USD 0, and the page does not explain it, so read the checkout terms.

Kiri Engine: common questions
How much does Kiri Engine cost?
Basic is free with every account. Yearly Pro is USD 79.99 billed yearly, equal to USD 6.66 a month. The page shows a Monthly and Yearly toggle but no monthly Pro price, and credit pack prices are not published. Check the checkout screen for renewal wording before paying.
What does the free Kiri Engine plan include?
Basic includes Photo Scan up to 150 photos and 2 GB per scan with 4K textures, OBJ, FBX, STL and GLB exports, unlimited LiDAR scans, in-app cropping, texturing, measurement and web app access. Paid features such as Gaussian splatting and 8K textures sit behind Yearly Pro.
Which AI features does Kiri Engine list?
The pricing page names AI-generated PBR materials and automatic rig generation on Yearly Pro. It does not describe the models behind them or whether your scans train them, so ask the vendor if that matters. The page does not say whether these features are metered or priced separately from the yearly fee.
Where does Kiri Engine process my scans?
The FAQ says data is stored and processed via KIRI cloud servers and that deleting an account removes data permanently. The policy opened names no hosting region, retention period or certification. Whether the policy permits other uses of your scans was not stated on the pages opened.
Is Kiri Engine suitable for survey work?
The plans center on creative output: textures, rigs, quad meshes and Gaussian splats. The pages describe no control points, accuracy reporting or survey deliverables, so surveyors should compare desktop packages that list those features. Output quality for measurement tasks is not described by the vendor either.
