Layered paper tabs orbit a vermilion sun as it crosses a geometric horizon.

Local-first · Chrome & Edge

Every tab gets
a horizon.

Give a lingering tab a date. When it arrives, make one clear decision: keep, schedule, bookmark, or close.

Free. No account. Your URLs never leave your browser.

Not another place to hoard tabs.

A deadline for deciding.

One small ritual

Tag now. Decide later.

Sunsets add intention without interrupting your current train of thought.

  1. 01

    Set the horizon

    Choose a date and leave a compact reason while the context is fresh.

  2. 02

    Review seven or fewer

    The badge counts what is due. Your daily queue stays deliberately finite.

  3. 03

    Choose an outcome

    Keep, defer, bookmark and close, or close—with an immediate undo.

Built for momentum

Four decisions.
No filing system.

Shortcuts make review feel like clearing a small deck, not reorganizing your digital life.

  • K Keep the tab open and preserve its rationale
  • S Schedule it seven days forward
  • B Bookmark it, then close the original
  • C Close it, with one-click reopen
