Textify is a Kotlin-based application designed to convert visual content into editable text. With Textify, users can capture photos and transform them into text which can then be edited, customized, and shared. The app also provides functionality to convert previously captured images.

Suitable For:

  • Students: Capture and convert lecture notes or study materials.
  • Professionals: Transcribe meetings or presentations without manual transcription.
  • Journalists: Convert visual content into textual form for articles or reports.
  • Researchers: Convert printed resources or notes into digital text.
  • Everyday Users: Transform image-based information into text for various needs.

Special Note: Textify supports multiple languages, with a special focus on the Maori language. However, users might occasionally face issues with macron interpretation.
