Brinn: The Membrane

The sensory organ for your second brain. Connects the web to your Brinn Vault.

Brinn is a Chrome extension that tracks and analyzes your website usage to provide a detailed view of how you spend your time online. Using background activity monitoring and idle detection, it calculates a focus score and generates a daily briefing of your top sites while storing all data locally for privacy. It also includes a command bar for manual session tagging and a rules engine that allows you to set limits or block distracting websites once your time is up.
