Six layers, each doing one job well. Together they change what YouTube is — from a feed that happens to you into a tool you happen to use.
The player, cleaned up and instrumented.

AI Summary modal
Transcript-aware summaries from your own key — Gemini, OpenAI, Mistral, DeepSeek or xAI. One button under the player.
Shorts eradication
Shorts disappear from the shelf, the sidebar and the grid — not hidden, gone.
Ad skipping
Skips pre-rolls and mid-rolls automatically, without polling the page into a profiler chart.
Autoplay terminator
The next video never starts itself. Continuing is always your decision.
Force highest quality
No more 480p surprises — the player opens at the quality your connection can afford.

The student
Lecture playlists without the sidebar of everything else. Pomodoro while studying, Sleep Guard after midnight.

The researcher
Watch Intent keeps sessions honest, topics show where the hours went, and the Tab Manager keeps sources sorted.

The evening scroller
Graduated unblock friction turns one more video into a decision. The morning briefing shows yesterday, gently.
Install from source in five minutes, close your first ring tonight, and read yesterday over coffee tomorrow.
