Stale Alert

For everything you saved once

Know when what you know stops being true.

Stale Alert re-checks the facts in your notes and bookmarks and shows you old versus new, with the source.

Why this exists

"I told a client the old threshold in a meeting. I'd saved it two years ago."

Grace Adeyemi, freelance accountant, Manchester. Works from 46 saved notes.

Sample person and sample figures throughout. General information, not tax or legal advice.

Step 1 of 2 · What to watch

Where does Grace keep what she knows?

Only facts get checked

A fast model reads each note and pulls out claims that can go out of date. Opinions, diary notes and passwords are skipped and never leave your device.

PRICE"A4 paper box £24.99 at Pennine Office Supply"
RULE"Register for sales tax above £85,000 turnover" sample figure
HOW-TO"Reports, then Export, then Trial balance"
SKIP"Felt good about the Hughes meeting." not a fact

    From now on, it keeps checking

    Things Grace uses weekly get checked daily. Everything else weekly. You only hear from it when something changed.

    Before your Monday close: the trial balance export moved.

    You open this note every Monday. LedgerLeaf removed the old Export menu in version 8.2. Updated steps are ready.

    Stale Alert sends this on its own, timed for when you'll need it. Nothing changes until you tap.

      GRAND MISSION · 3 YEARS

      Nobody acts on a dead fact again.

      1. Year 1: personal libraries for freelancers, accountants, nurses, teachers, anyone who works from saved notes.
      2. Year 2: shared team libraries and a public "fact freshness" layer: when one person confirms a change, everyone watching the same fact gets it in minutes.
      3. Year 3: a quiet check on everything you read and write. Draft a pitch that quotes an old statistic and it says so before you hit send.
