Frequently asked questions

01 How much free space do I need for Question.AI - Chatbot&Math AI?

At least 60.2 MB for the file itself, plus a few hundred megabytes for updates and cache once it is installed.

02 Is it safe to install Question.AI - Chatbot&Math AI from here?

Files come from our download library or external sources and are not modified by us. Check the package name (com.qianfan.aihomework) and developer before installing.

03 How long does the download take?

60.2 MB typically takes under a minute on Wi-Fi or 5G and a few minutes on 4G.

04 Why does the download or install fail?

Usually not enough storage, an Android version below the requirement (Android 7.0+), an interrupted connection, or installs from unknown sources being blocked in settings.

05 APK or XAPK, what is the difference?

An APK installs directly. An XAPK bundles the APK with extra data files and needs a split-APK installer; see the install guide.

06 How do I install it after downloading?

Open the file, allow installs from this source when Android asks, and follow the prompts. Step-by-step instructions with screenshots are in the install guide.
