About

WebTM

Web Time Machine quietly remembers the readable text of every page you visit and makes your history actually useful. โ€ข Full-text search โ€” find a page by something it said, not just its title or URL. โ€ข One-line AI summaries โ€” skim what each page was about. โ€ข Synced across your devices โ€” capture on iPhone and your Mac/PC, search anywhere. โ€ข Private to your account โ€” your history syncs to your own space, never sold. โ€ข Auto-expiring โ€” history rolls off on a retention schedule; delete anything instantly, and deletions propagate everywhere. Capture runs in a Safari Web Extension and is fully passive โ€” it never changes the pages you browse, and nothing is recorded until you turn it on and sign in.
