Next release: Cache 1.1

Your own library, on every device

What Cache 1.1 brings, and where each feature stands on each kind of device. Must-haves are the promise: 1.1 ships when they all work. Stretch features ride along if they are ready, and never hold the release.

Devices in 1.1: Android, iPhone and iPad, and Linux and Raspberry Pi (the full app in a browser). Windows comes in 1.2.

Where things stand

Updated 11 Nov 2026. Cache 1.1 is in testing on phones. It becomes stable when every must-have below works on each kind of device and Ask is fast enough.

Testing now: Cache 1.1.0 (49)

  • CheckedLaunch check on a Pixel 8, updating from the build before: libraries and linked devices are kept; watched folders, map icons and pin styles, the question that sets how settings sync, and Stop while Ask is searching.
  • LiveOn Google Play testing (internal, closed and open).
  • LiveOn TestFlight for public testers.
  • WaitingGoogle Play for everyone, until 1.1 is finished.

Phones and tablets

  • WorksNew Library and Bookshelves, adding PDFs with OCR, search inside your books.
  • TestingWatched folders (new PDFs you drop in a folder are added on their own), map icons and colors for notebooks and places, and one question that sets how settings sync between two devices.
  • BuildingNotebooks that sync cleanly between devices, full-size photos, and a clearer log for problem reports.
  • BuildingAndroid Auto, being readied for Google's car review. CarPlay follows.

Cache on Linux and Raspberry Pi

  • WorksMaps in the browser.
  • MergedThe new Library, routing, and meaning search, waiting for their browser checks.
  • In reviewDownloads from other sites, directions, the PDF reader, regions, weather, chat history, models, videos, and the first part of sync.
  • DesigningThe storage page, sharing, the update notice and location wording.

Ask: speed and accuracy

Goals: the first words within 15–20 s on a Pixel 8, then writing faster than you read · at least 85% of answers mostly correct

What we found

  • SlowThe phone reads the question and its sources far slower than it should.
  • SlowA changing line in the instructions throws away work Cache had saved between questions.
  • AccuracySome answers skip searching your library when they shouldn't.

What we're doing

  • MeasuringTiming older builds on the same phone to find where it slowed down.
  • TestingFixed instructions, checked against a set of real questions before they ship.
