Crystal Ball helps you get concise AI answers while using other apps.
Choose the part of the screen you want Crystal Ball to read, start screen sharing, and tap the floating ball whenever a new question appears. Text recognition runs on your device, then the recognized text and your instruction are sent securely to generate an answer. The screenshot itself is not uploaded.
Key features:
- Get quick answers without switching apps
- Select exactly which part of the screen should be read
- Move the floating ball anywhere on screen
- Tap again to replace an in-progress request with the latest screen content
- Choose Latin, Chinese, Japanese, Korean, or Devanagari text recognition
- Customize the instruction sent to AI
- Save separate reading areas for portrait and landscape
- Stop screen sharing at any time from the app or notification
Privacy is built into the workflow. Crystal Ball only starts screen sharing after your explicit action. Screen images are processed on your device for text recognition and are not uploaded. Avoid selecting passwords, payment details, health information, or private conversations.
Crystal Ball requires permission to display the floating ball over other apps and Android screen-sharing consent. A monthly subscription with a 3-day introductory trial and a one-time unlock are available through Google Play.
