Installation Guide
Download and set up Kai on iOS or Android
Overview
Kai is a mobile app available for iOS and Android devices. There are two separate apps — one for instructors and one for students — each tailored to the specific needs of that role.
Kai is currently available through our beta program. Contact your institution’s administrator or visit our contact page to request access.
System Requirements
Before downloading, verify your device meets the minimum requirements:
| Requirement | Minimum |
|---|---|
| iOS | 16.0 or later |
| Android | 8.0 (Oreo) or later |
| Account | Institutional email address |
| Connection | Internet connection required |
Sign in with the email address your institution uses for work or study. Personal email addresses (Gmail, Yahoo, etc.) are not recommended — use your school or organization’s email account.

The Kai Instructor app lets you create sessions, generate quizzes and feedback requests, capture lectures, and review analytics.
iOS (iPhone or iPad)
- Open the App Store on your iPhone or iPad
- Tap Download on the App Store (link to be finalized)
- Tap Get and authenticate with Face ID, Touch ID, or your Apple ID password
- Once installed, open Kai Instructor and tap Sign In
Search for “Kai Instructor” in the App Store search bar. Make sure you are on iOS 16 or later. If the app does not appear, your institution may be distributing it through TestFlight — see the note on beta access above.
Android (Phone or Tablet)

The Kai Student app gives you access to your courses, AI tutoring, quizzes assigned by your instructor, and feedback forms.
iOS (iPhone or iPad)

If your institution is in the beta program, your instructor or administrator will send you a direct installation link. Open that link on your Android device or follow the TestFlight invitation on iOS.
Browser Access — No App Required
Students can complete individual quizzes, homework, and feedback forms directly in a web browser without installing anything.
How it works:
- Your instructor shares a link or displays a QR code during class
- Tap the link or scan the QR code with your phone’s camera
- Complete the activity in your browser
- No account or app installation needed for one-off activities
Browser access covers individual questionnaire activities. To access your full course history, the AI tutoring assistant, and ongoing course materials, install the Kai Student app.
Signing In
Both apps use the same sign-in process.
- Open the app and tap Sign In
- Enter your institutional email address
- Choose your sign-in method:
- Google — sign in with your Google Workspace account
- Microsoft — sign in with your Microsoft 365 account
- Email and Password — enter the password you set when your account was created
- If this is your first time, follow the on-screen prompts to complete your profile
Sign in with the email address your school or organization assigned to you. Using a personal email address may prevent you from accessing your courses.
If your institution has set up accounts for you, you may receive a welcome email with sign-in instructions. Check your spam folder if you do not see it within a few minutes.
Troubleshooting
App Does Not Appear in the App Store or Google Play
- Verify your device meets the minimum OS version (iOS 16+ or Android 8.0+)
- Make sure you are signed in to the correct App Store or Google Play account
- Your institution may be distributing the app through a beta channel — contact your administrator for a direct link
“Sign In Failed” or Account Not Recognized
- Confirm you are using your institutional email, not a personal email address
- Check that you selected the correct sign-in method (Google, Microsoft, or Email/Password)
- If your administrator recently set up your account, allow a few minutes for the account to activate
Push Notifications Not Arriving
- On iOS: Go to Settings → Notifications → Kai and ensure notifications are enabled
- On Android: Go to Settings → Apps → Kai → Notifications and ensure they are turned on
- Check that Do Not Disturb or Focus mode is not blocking notifications
- Restart the app and sign in again if notifications were recently enabled
App Crashes on Launch
- Close the app completely and reopen it
- Check that your device has enough free storage (at least 200 MB recommended)
- Update to the latest version of the app from the App Store or Google Play
- If the problem persists, uninstall and reinstall the app — your data is stored in the cloud and will be restored on sign-in
QR Code or Browser Link Not Working
- Make sure you have a working internet connection
- Try opening the link in a different browser (Chrome or Safari)
- Ask your instructor to regenerate the link if it has expired
