YouTube content creators lack comprehensive analytics and research tools directly within the YouTube interface; this extension embeds channel comparison, advanced metrics, thumbnail management, sentiment analysis, and filtering capabilities directly into YouTube pages

User installs the extension, optionally logs into their Nexlev account via app.nexlev.io. When browsing YouTube, the extension injects enhanced analytics overlays, filter tools, and creator utilities directly into YouTube pages (home, search, video, channel, shorts feed). Users can access a popup dashboard for aggregated analytics, compare channels, and manage research workflows.

Target users: YouTube content creators / YouTube channel managers / YouTube marketing researchers / Content strategy teams

Source code is heavily minified/bundled (Parcel bundler), making it difficult to trace specific business logic for login gates and paid feature checks
The large feature wrapper files (yt-public-features-wrapper.44023b7d.js at 4.6MB) contain the core YouTube injection logic but are too large to fully analyze
Cannot determine from source code alone whether the Nexlev backend service has paid tiers that gate extension features

Login required: Yes
Reason: The extension has a dedicated content script 'login-callback.b50b5a44.js' injected on https://app.nexlev.io/* (manifest line 3), which is an authentication callback handler for the Nexlev service. The extension communicates with backend APIs at prod.dashboard.nexlev.io/api and dashboard.nexlev.io, indicating it relies on a destination service that requires account authentication. The login flow redirects users to app.nexlev.io for authentication before granting access to advanced analytics features.
