You have too many tabs open. You'll never go back to most of them. day1tabs closes your tabs at midnight and shows you which ones you actually used — sorted into "Used" and "Didn't use." Reopen what matters. Let the rest go. → Never-close domains stay open (Gmail, Docs, Salesforce) → Pinned tabs and active tab always protected → Everything recoverable until next auto-close Zero data collection. Everything local. Free forever. Built by a solo dev with too many tabs and not enough discipline.
