ScreenMind vs Polycam
Side-by-side comparison of features, pricing, and ratings
At a glance
| Dimension | ScreenMind | Polycam |
|---|---|---|
| Primary Use | Local screen memory & AI analysis of desktop activity | 3D scanning & photogrammetry for objects, spaces, floors, drones |
| Platform | macOS only (currently) | iOS, Android, Web, Drone |
| AI Model | Google Gemma 4 (local, 4GB GPU) | Proprietary AI for photogrammetry & 3D reconstruction |
| Key Differentiation | Privacy-first, on-device screen activity search & recap | Real-world spatial capture to 3D models & floor plans |
| Integration | MCP Server, Claude, Cursor, VS Code, Obsidian, Notion, Slack | SketchUp, Blender, AutoCAD, Revit, Unity, Unreal Engine |
Don't pit them head-to-head — they solve completely different problems. If you need high-fidelity 3D scanning of real-world spaces with floor plans and drone support, Polycam is the clear choice, especially at under $12/mo for Pro. If you want a private, local screen memory that indexes your entire desktop activity and lets you chat with it, ScreenMind is a unique, free, and powerful tool — provided you're on macOS.

Open-source macOS app that captures your screen, analyzes it locally with Gemma 4, and builds a searchable, chat-able AI memory.

Frequently Asked Questions
ScreenMind vs Polycam: which should you choose?
Don't pit them head-to-head — they solve completely different problems. If you need high-fidelity 3D scanning of real-world spaces with floor plans and drone support, Polycam is the clear choice, especially at under $12/mo for Pro. If you want a private, local screen memory that indexes your entire desktop activity and lets you chat with it, ScreenMind is a unique, free, and powerful tool — provided you're on macOS.
Can Polycam run on any smartphone?
Polycam works on iOS (LiDAR supported on newer models) and Android (ARCore). Photogrammetry works with any camera; LiDAR scanning requires a LiDAR-equipped iOS device.
Does ScreenMind work on Windows or Linux?
Currently, ScreenMind is macOS-only. There's no announced support for Windows or Linux.
How do ScreenMind's analysis modes differ?
ScreenMind offers Accurate (~76s per screenshot), Balanced (~40s), and Fast (~12s). Faster modes use a lighter version of the Gemma 4 model, trading detail for speed.
Can I export Polycam scans to CAD software?
Yes, Polycam integrates with SketchUp, Blender, AutoCAD, Revit, Unity, Unreal Engine, Maya, and Cinema 4D. Exports include OBJ, FBX, PLY, and point clouds.
Is ScreenMind's meeting transcription speaker-labeled?
ScreenMind provides meeting transcription for Zoom/Teams/Meet. Speaker labeling is based on system audio streams, but accuracy depends on audio quality and overlap.
Does Polycam have a free tier?
Yes, Polycam has a free tier with limited exports and lower resolution. Pro ($12/mo) unlocks HD exports and floor plans; Business ($50/mo) adds advanced features.
Can I use ScreenMind offline?
Yes, ScreenMind works entirely offline as all processing is local. No internet connection is required for capture, analysis, or search.
What is Polycam's Gaussian splatting?
Polycam's Gaussian splatting tool creates view-dependent 3D representations from photos, especially useful for real-time rendering in Unreal Engine as shown in the latest tutorial (2026-05-28).
