Sleep Timer for Google Chrome

Sleep timer, keep-awake modes, and video-aware auto close for Google Chrome.

**Sleep Timer for Google Chrome — Automatic Closing, Schedules, and Screen Control** No more watching the clock, closing tabs manually before bed, or worrying that a video will keep playing all night. This extension helps you manage Google Chrome by running timers, following schedules, keeping the screen awake, and completing a viewing session when a video ends. Everything can be configured in just a few clicks, without complicated menus or unnecessary steps. **Main Features** **Countdown Timer** Choose how many minutes should pass before an action is performed. When the timer ends, the extension can close only the selected tab or all Google Chrome tabs and windows. This is useful before sleep, while relaxing, when listening to music, or whenever you want to limit your browser time in advance. **Close at a Specific Time** Schedule an action for a specific time, such as 11:00 PM. If the selected time has already passed, the task will automatically move to the next suitable day. **Independent Tasks and Schedules** Create separate tasks for different times and days of the week. Tasks can run: — once; — every day; — on weekdays only; — on weekends only; — on selected days of the week. Saved tasks work independently from other modes. Starting a countdown timer, ON mode, or VID mode does not delete or reset your schedules. **Video Mode — VID** Enable VID in the tab where you are watching a movie, series, live stream, or other video. The extension monitors only that specific tab, keeps the screen awake during playback, and performs the selected action after the video has been confirmed as finished. Switching to another tab does not transfer VID mode, and another page cannot accidentally end the active video session. **Keep Awake Mode — ON** Prevent the screen and system from going to sleep when you need to: — finish watching a video or live stream; — read a long article; — complete a download; — keep the browser active while working; — monitor information displayed on the screen. The mode can be enabled with one click and disabled just as quickly. **Close One Tab or the Entire Browser** Choose the option that best fits your needs: — close only the tab associated with the active function; — close all Google Chrome tabs and windows. The selected closing mode applies to timers, schedules, and VID mode. **Warning Before Closing** Before performing an action, the extension displays a warning and can play a notification sound. From the warning window, you can: — cancel the upcoming closing action; — postpone it for a few minutes; — continue working without losing the saved schedule. **Clear Visual Status** The extension icon shows the current operating mode: — IDLE — waiting; — ON — keeping the screen awake; — OFF — active timer or scheduled task; — VID — monitoring video playback. For countdown timers, the remaining time is displayed directly on the icon, so you can check the current status without opening the extension window. **Battery Protection** When the battery reaches a critically low level, the extension can automatically disable ON and VID modes to prevent the device from continuing to drain power while the screen is being kept awake. **Quick Access** The main functions are available not only from the extension window, but also through the context menu and keyboard shortcuts. **Free Version** The free version includes: — timers of up to 30 minutes; — one one-time scheduled task; — VID mode for up to 30 minutes; — Keep Awake mode; — the choice between closing one tab or all browser windows; — a warning before the selected action is performed. **Premium Version** Premium is designed for users who regularly rely on automatic closing and scheduled tasks. It unlocks: — timers longer than 30 minutes; — VID mode without the free time limit; — multiple independent tasks; — repeating schedules for selected days of the week; — additional automatic closing controls. **Important** The extension works inside Google Chrome. It manages browser tabs, windows, and the screen keep-awake mode, but it does not shut down your computer or change system settings in Windows, ChromeOS, or macOS.
