Three Operating Modes

Timer Mode — Pure time management, no content filtering.
Daily sub-mode: a global time quota. Once exhausted, immediate redirection.
Session sub-mode: work/rest cycles. Configure number of sessions, duration and break time. YouTube is blocked during breaks and after the last session.
Keywords Mode — Content-based filtering using video titles and descriptions, with accent- and case-insensitive matching.
Global sub-mode: a single shared timer for all keywords.
Individual sub-mode: a dedicated timer per keyword, with progress bar and remaining time on hover.
Mix Mode — Combines a daily timer (absolute ceiling) with individual keyword timers. Without a detected keyword, only the daily timer counts down. With a keyword, both timers count down in parallel.

Time Management

Time only counts while a video is actively playing. Paused video = paused timer.
Time keeps counting in background tabs or when the browser is minimized, as long as a video is playing.
Anti multi-tab stacking: 1 real second = 1 counted second, regardless of how many videos are open.
Configurable reset time (midnight by default), applied to all modes.
Real-time counter always visible, adapted to the active mode.
Supports regular videos, Shorts, minimized player and embedded players on third-party sites.
Configurable redirect URL in administration settings.

Keyword Import / Export

Export keyword lists to JSON (global and individual keywords with their timers).
Import from JSON with smart merge that preserves already consumed time.
Available in Keywords and Mix modes.
