Step 1
Load ChessIQ once
Open the app online so the browser can cache the app shell and engine files.
Offline-capable
Offline chess analysis with honest boundaries
ChessIQ is useful without pretending the whole internet disappears. Saved reviews, Training, and Archive can work from local browser storage after the app is loaded.
Saved reviews reopen from local storage
Training state is browser-local
Fresh public lookups need internet
The app shell and engine must be cached first
Review flow
Start with one game
These pages all lead back to the same place: import a game, review it, and use what the review found.
Step 2
Review and save
Import a game, run analysis, and let ChessIQ store the review on this device.
Step 3
Come back offline
Open Archive, Training, or saved review data from browser storage.
Step 4
Reconnect for imports
Username lookup, fresh game links, and analytics resume when the connection is back.
Proof
What offline mode is actually good for
Reopening work
Previously reviewed games can stay useful without another network import.
Training continuity
Saved positions remain available so practice is not blocked by spotty connectivity.
Local-first storage
The main review artifacts live in the browser instead of a required account database.
Clear failure states
Fresh public imports should say they need a connection instead of hiding the cause.
Quick answers
Can I fetch new games offline?
No. Fresh public imports need an internet connection.
Can I train offline?
Yes, when Training positions were already saved in this browser.
Can I reopen old analysis?
Saved reviews can reopen from local storage after the app has loaded and cached the needed files.
Is this cloud sync?
No. Offline capability is local to the browser/device.
