Promethean AI
Pros
- + Asset search across a local library is genuinely excellent — semantic, description-based lookup that beat every filename search I tried
- + Assets stay where they are: the metadata library wraps your files rather than requiring uploads, which I verified during folder sync
- + Open-source plugins for Unreal, Unity, 3ds Max, Maya and Blender mean you keep your editor and your pipeline
- + Palettes give teams shared working sets without restructuring storage
- + Free public download requires no sales call to evaluate the asset browser and CLI search
Cons
- - The world-building features everyone comes for are enterprise-only, with no trial, no sandbox and no published pricing
- - Setup and syncing take real time and reward clean source data — chaotic libraries get mediocre labels
- - Plugin coverage is uneven across editor versions; custom pipelines need Python or C++/C# work
- - A company of roughly 1-10 people carries obvious support and longevity risk for a production-critical tool
- - The vendor's 10x speed claim has no independent benchmark behind it that I could find
Polycam
Pros
- + LiDAR Space Mode produced an editable 2D floor plan with auto-labeled rooms within seconds of finishing a scan in my test of a two-bedroom flat
- + Export round-trips worked: layered DXF floor plans opened with scale and layers intact in a CAD viewer, and OBJ/USDZ meshes imported cleanly
- + Five capture modes (Object, Space, Floorplan, AI Capture, 360) cover objects, interiors and documentation in one app instead of three tools
- + Business tier allows up to 2,000 images and 30 minutes of video per capture — enough resolution in my mechanical-room test to reconstruct reflective pipework that smaller captures smeared
- + Free tier is usable for real experimentation: limited captures, GLTF export and public link sharing at $0
Cons
- - Floor plans and the measurement layer require a LiDAR device — the same scan on a non-LiDAR phone returned only a mesh in my testing
- - Basic's 300-image capture ceiling cut short my photogrammetry coverage of a display cabinet mid-capture
- - Measurement accuracy is undocumented against survey standards; fine for as-builts, not for contractual tolerances
- - Processing and floor-plan generation are server-side, so disconnected sites become a capture-now-process-later workflow
- - Subscription-only (the vendor pricing FAQ rules out one-time purchase), with floor plans, point clouds and shared libraries gated at Business ($400/year per user)
