About

| Monitor system memory pressure and safely sleep inactive Chrome tabs.

Keep large tab sessions under control without losing the pages you still need.

Tab Memory Monitor & Smart Sleep shows your computer's current memory pressure,
ranks inactive tabs by cleanup priority, and lets you unload tabs while keeping
them visible in Chrome. Sleeping tabs reload when selected again.

| Features

- View available and used system memory.
- See whether memory pressure is healthy, moderate, high, or critical.
- Rank tabs by cleanup priority using inactivity and safety signals.
- Sleep individual tabs without closing them.
- Run Smart Cleanup manually.
- Optionally run Smart Cleanup when available system memory becomes low.
- Protect pinned tabs, audio-playing tabs, Gmail, Google Docs, and any other
  websites you choose.
- Review a 60-minute system memory graph.
- Review cleanup history and observed changes in available memory.
- Keep all extension data local to your device.

Stable Chrome does not provide extensions with exact memory usage for each tab.
The extension therefore shows real system-wide memory and separately ranks tabs
by inactivity-based cleanup priority. It does not present cleanup priority as
per-tab memory.
