SponsorBlock
Use the community-run SponsorBlock database for instant, exact segment skipping on videos others have already marked. The AI only runs when SponsorBlock has nothing. Privacy-preserving: your video is looked up by a hashed prefix, so the server never learns which video you watched.
Skipping behavior
YouTube extras
Optional annoyance removers. Each is off by default.
Ad blocking
Filter rulesets
Each blocking list is a set of network rules. Turn them on or off individually here. Loaded is how many rules Chrome currently has active — if a list is on but shows nothing loaded, Chrome hit its per-session rule limit; restart the browser to clear it.
Behavior & exceptions
Sites where ad blocking is paused. Add sites here, or use the popup's “Pause ad blocking here” toggle while on a site.
AI & privacy
Sponsor detection AI
Transcripts of the videos you watch are sent to the selected AI for analysis. Beyond that, only the anonymous diagnostics described under Privacy below ever leave your browser.
Your key is stored locally in this browser and sent only to the provider you selected.
Privacy
These diagnostics and daily usage counts are the only data Ad Sensei ever sends home. Transcripts go only to the AI provider you chose above, and everything else stays in this browser.
Filter lists: bundled with this version.
Analytics
What Ad Sensei has handled for you. All-time totals, with today's count in the sub-line. Stored only in this browser.
Skip performance
How long ad breaks actually take to clear, from the last 400 skips on this device. This is the number that decides whether blocking YouTube's first-party ads is worth the ad-blocker notices it provokes — under a couple of seconds and reactive skipping costs you almost nothing.
No skips recorded yet. Watch a few videos with ads and come back.
Reset
Zero the lifetime and this-session counters above (and in the popup). Your settings are untouched.
