Claude Session Keeper

About

Claude Session Keeper is a productivity extension for Claude.ai users who want uninterrupted access to their 5-hour usage sessions.Claude's usage resets on a rolling 5-hour window.

If you don't start a session, that window goes to waste. This extension monitors your usage page automatically, detects when your session is idle, and sends a starter message to kick it off — so your session clock starts when it should.What it does:

Automatically visits claude.ai/settings/usage on a schedule and checks whether your current session is active or idle

If idle, opens a new chat and sends "hi" to start the session
Live countdown badge on the extension icon shows time remaining (e.g. 4h02, 42m) — updated every minute

Desktop notification fires the moment your session resets so you can jump back in immediately

Popup shows current session usage bar (% used + time until reset), weekly model limits (All models, Claude Design), and extra usage spend
