On the Web.
On Your Phone.
With Your Own Library.
AccelaStudy® AI Chess has two clients in development: a web app, and an app for iPhone® and iPad®. Both read the same curriculum and both keep your practice on your device.
Both are in development. We have not announced a release date or a price.

How the library lives on your device
Study Offline.
Keep It Private.
The full puzzle library is 6,193,530 puzzles in 3,102 packs. You choose what to download.
Download what you want
Pick a focused set for a trip or build a larger library over time. Downloading the whole library is about 1.71 GB.
Practice with no connection
Installed puzzles are stored on your device. Practice, hints, and solution review work the same way when your connection does not.
Pause and pick up again
A paused or interrupted download resumes where it stopped. A pack is checked before it is activated, so a bad download cannot replace one that works.
Private practice history
Your attempts and results are saved on your own device. Sync is planned for people with an AccelaStudy AI account, and practicing without an account is the plan too.
Storage
Browser Limits.
Device Limits.
The two apps do not run out of room in the same way.
In a browser, the browser decides how much a site may store, and that limit differs between browsers and devices. A computer with plenty of free disk can still be told no. The web app is designed to explain a refused download and to keep the puzzles and history you already have.
On iPhone or iPad, the limit is the free space on the device. The full library expands to about 12.98 GB before indexes and overhead, which is more than many phones have to spare, so most people will want to choose a smaller set. The app is designed to show the download size and your free space before you start.
Downloaded puzzles and practice history are kept separately. Your history does not depend on which packs are installed.
Between your devices
Sync Is Planned.
It Is Not Built.
Today each development app keeps its own history on its own device. We plan to add sync through an AccelaStudy AI account, so a session on your phone can continue on the web.
Practice will stay usable when you are signed out or offline. Signing in is planned to move your existing history only when you ask it to, and signing in as someone else will not expose or upload their history.
About the puzzle source: the puzzles come from the Lichess puzzle database, released under CC0. AccelaStudy AI Chess is not affiliated with or endorsed by Lichess.
