Nico Nico Commons' native interface does not support continuous/list-based playback of multiple audio files. This extension enables users to play a sequence of music素材 (materials) from search results or upload pages in a playlist fashion.

1. User navigates to a search or upload page on commons.nicovideo.jp. 2. Extension's content script detects the page and extracts audio preview URLs from the listed items. 3. User enables the player via the popup toggle. 4. The overlay player appears; user can play, pause, skip tracks, or bookmark. Tracks auto-advance when one ends.

Target users: Nico Nico Commons users who want to listen to multiple music素材 in a playlist / Content creators and music enthusiasts browsing commons.nicovideo.jp

The extension relies on the public preview API of Nico Nico Commons, which may change or require authentication on the destination site side. The analysis assumes the preview API remains publicly accessible without extension-side login. If Nico Nico Commons changes its API to require authentication, the extension's functionality may break, but that is outside the extension's own code.

Monetization

No paid features detected

The extension is completely free with no paid features, subscriptions, or billing logic. It uses a public preview API (/api/preview/get) to stream MP3s. The keyword 'pro' found in static analysis was a false positive from jQuery license text and generic variable names, not related to paid plans.

Confidence: 95
Payment platform: --
Source: AI / High
Login required: No
Reason: The extension itself does not implement any login mechanism, nor does it require the user to authenticate to use its features. It operates on public search and upload pages of commons.nicovideo.jp. While the destination site (Nico Nico Commons) may require login for some features, the extension's core workflow (listing and playing preview MP3s) works on public pages without extension-side auth.
