AI product read

View CAD files and 3D models in Google Drive and Gmail

Allows users to view DWG, DXF, and other CAD/3D files directly in the browser without downloading them or needing expensive software like AutoCAD.

User installs extension -> Extension injects buttons into Google Drive/Gmail UI -> User clicks button -> Extension opens side panel -> Side panel loads iframe from cadviewer.co -> User authenticates with cadviewer.co (if not already) -> File is processed and displayed in the viewer.

Target users: Architects / Engineers / Construction professionals / Anyone needing to view CAD files without specialized software

The extension relies heavily on the external cadviewer.co service. The exact login requirements (free vs paid) of that service are not fully visible in the extension code, only the relay mechanism. The extension code is minified/bundled, making some analysis harder.

Monetization

No paid features detected

The extension source code contains no references to payment gateways, subscription management, license keys, or premium feature gating. The keyword 'pro' found in static analysis corresponds to React internal symbols (e.g., `react.profiler`, `react.production`) and not paid features. The extension appears to be a free wrapper/launcher for the cadviewer.co service. While the destination service may have paid plans, the extension itself does not implement paid features.

Confidence: 90
Payment platform: --
Source: AI / High
Login required: Yes
Reason: The extension acts as a client for the external service cadviewer.co. The sidepanel injects an iframe pointing to `https://cadviewer.co/viewer`. The extension handles authentication relay (`authRelay.js`) receiving `EXTENSION_AUTH_COMPLETE` and `sessionToken` from the webapp, storing it in `chrome.storage.local`. The service worker intercepts OAuth state parameters from `cadviewer.co` to handle the login flow. While the extension itself doesn't have a login UI, the core workflow of viewing CAD files requires the user to be authenticated with the destination service (cadviewer.co) to process the files.
