day1tabs is a Chrome extension designed to help users manage browser tab overload by automatically closing tabs at midnight. The main purpose is to provide users with a fresh start each day while preserving access to tabs that were actually useful.

The extension automatically closes your tabs at midnight and classifies them into "Used" and "Didn't use" categories. It includes never-close domains that stay open automatically, such as Gmail, Docs, and Salesforce. Pinned tabs and the active tab are always protected from closure. Everything that gets closed remains recoverable until the next auto-close cycle.

The extension works by monitoring tab usage throughout the day and then performing an automatic reset at midnight. It uses local classification to sort tabs based on actual usage patterns, allowing users to see which tabs were genuinely useful versus those that were merely opened and forgotten.

The primary benefit is helping users maintain a cleaner, more organized browser workspace each day. It eliminates tab clutter while ensuring important tabs are preserved and easily recoverable if needed. Users can reopen any closed tab with a single click.

The product is built specifically as a Chrome extension with zero data collection and everything stored locally. It's designed for users who struggle with browser tab overload and want an automated solution to maintain digital cleanliness.
