User clicks the extension icon → a new tab opens with index.html → user clicks 'Open File' to select a local .obj file or 'Try Opening Sample OBJ' → the file is parsed and rendered as a 3D WebGL scene using Three.js → user can rotate, zoom, and pan the model with trackball controls.

Target users: 3D modelers and designers who need quick OBJ file previews / CAD users wanting to view exported OBJ files / Students and hobbyists working with 3D models

The bundled sample model 'Leonardo.obj' is referenced but not present in the file listing, so the default sample feature may not work
The js/popup.js contains speed slider code that references DOM elements not present in index.html (selectedSpeed, currentSpeed), suggesting it may be leftover/inactive code from another extension

Monetization

No paid features detected

No subscription, payment, premium tier, upgrade prompt, or billing API found in the source code. All keyword matches for 'paid' are false positives: 'pro' in locale files means 'try' in non-English languages (e.g., Czech 'Prohlížeč OBJ'), 'prototype' in JS code, and Bootstrap CSS license text. The extension offers all its features (file upload, default sample model, 3D rendering with trackball controls) for free.

Confidence: 95
Payment platform: --
Source: AI / High
Login required: No
Reason: The extension operates entirely locally in the browser. The core workflow—opening a local OBJ file via file picker and rendering it with Three.js—requires no authentication, no account, and no server-side login. No login UI, no auth tokens, no user account creation, and no redirect to any login page exist in the source code.
