Youtube Time Limiter
View on Chrome Web StoreChrome will indicate if you already have this installed.
Overview
**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.
- *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.
- 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 and minimized player.
- 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.
**Security and Parental Control**
- Password protection for all settings.
- Modify or remove password (leave field empty to disable).
- ON/OFF button also password protected.
- 100% local data — nothing is sent to external servers.
**User Interface**
- Clean, modern and compact design with collapsible sections.
- Dynamic remaining time display adapted to the active mode.
- Individual keywords are collapsible: name visible, details on click.
- Multilingual: *EN*, *FR*, *DE*, *IT*, *ES*, *JA*, *PL*.
- Automatic browser language adaptation.
