notsponsored par zyluxXD

notsponsored automatically marks and skips sponsored segments on YouTube. It checks SponsorBlock first and can fall back to analyzing English captions locally when no community segment is available.

Features:

• Automatically skips detected sponsor segments
• Provides an Undo button to undo skipped segments
• Marks detected segments on the video timeline.
• Supports SponsorBlock-only, local-only, and local-fallback detection modes.
• Lets you disable scanning for individual channels.
• Includes adjustable start and end trimming for sponsor segments.
• Tracks skipped segments and estimated time saved.
• Can optionally seek YouTube ads to their end.
• Offers optional LLM verification through a OpenAI-compatible provider configured by the user.

The local caption analysis runs entirely inside the browser. The optional LLM processing is disabled by default and requires the user to configure a provider, grant Firefox’s data permissions, and enable it.

The extension works best on videos with usable English captions.
