Common questions
Does chat need an internet connection?
No. Once a model is downloaded, replies are generated on your phone and chat works in airplane mode. The app connects only to download models, check for catalog updates, and for account, purchase or report features you choose to use.
Which Android phones are supported?
Android 8 or later on a 64-bit processor. The app reads your phone’s actual memory: most small models need at least 3 GB of RAM (4 GB recommended), the 4B-class models need 6 GB (8 GB recommended), and the largest catalog model, Qwen 3.5 9B, needs 13 GB. The iOS build is in private testing.
A model says “Needs at least X GB memory”.
The app compares the model’s minimum with the memory your phone reports, which can be a little below the advertised figure. This check cannot be overridden, so choose a smaller model.
My download paused or stopped.
Downloads run in the background and continue while you use other screens. Wi-Fi-only downloads are on by default, so a transfer waits for Wi-Fi unless you turn that off in Settings. Force-stopping the app can interrupt a transfer; reopen the app and tap Resume. Every file is checked against its exact size and SHA-256 hash before it becomes available, so a partly downloaded model is never marked installed.
Replies stop mid-sentence.
Each model has its own Max output tokens setting in Settings, from 64 up to the model’s context size minus 256. The default is 512, or 1,536 for reasoning models; raise it for longer replies. Conversations use up to 2,048 tokens of context (4,096 for reasoning models), and older turns are trimmed to fit.
Where is my chat history, and how do I delete it?
It is saved in the app’s private storage on your phone. Turn off Save chat history in Settings to stop saving, use Export conversations to keep a copy, or Clear chat history to remove everything. Long-press a chat title to delete a single conversation.
How do I remove a downloaded model?
Open Models → On your device → the model’s three-dot menu → Delete. This frees the storage the model used.
How do I report a bad reply?
Use Report on the reply. You review and edit the excerpt before sending; only that excerpt, the model ID and your chosen reason are sent, never the rest of your conversation. No account is needed. Reports are limited to five per hour.
What happens to my models if Offline Plus ends?
Downloaded models stay usable offline after a subscription ends or you sign out. Plus controls access to new Plus downloads, not the models already on your phone.
