AI product read

360-degree panorama and VR viewer

Allows users to easily convert local images (JPEG, PNG, TIFF) and videos (H.264) into shareable 360-degree panoramic or VR URLs.

User right-clicks an image/video -> selects 'Open with GRUU VIEWER' OR opens popup -> drags file or selects file -> uploads to viewer.gruu.jp -> receives redirect URL to view/share.

Target users: Users wanting to share 360 photos/videos / Social media users / Real estate or tourism professionals

The extension relies on the external service 'viewer.gruu.jp' for processing. If this service requires login or has paid tiers not visible in the extension code, it would not be detected here. However, the extension itself does not enforce login or payment.

Monetization

No paid features detected

The extension is free. The Web Store description explicitly states 'No Ads, no tracking and free to use without registration'. The code contains no references to payment gateways, subscription management, or feature gating based on payment status. The keyword matches for 'pro' and 'license' are false positives from library headers (jQuery, SweetAlert2) and generic words.

Confidence: 95
Payment platform: --
Source: AI / High
Login required: No
Reason: The extension explicitly states 'free to use without registration' in the Web Store description. The source code shows no login UI, no authentication tokens passed to the API, and no session management. The workflow involves uploading files directly to the destination service without any credential exchange.
