Challenges & solutions
The technical problems our team solved to ship a reliable, unified mobile experience.
Accurate Text Selection and Interaction
Allowing users to precisely select individual words, lines, or text blocks from detected content while preserving a natural and responsive interaction experience required intelligent text mapping and touch handling.
Reliable OCR Across Diverse Images
Extracting accurate text from documents, screenshots, and photos with varying lighting conditions, fonts, orientations, and image quality required robust image preprocessing and OCR optimization.
Privacy-First On-Device Processing
Performing all text recognition locally without sending images or extracted content to external servers required efficient on-device AI processing while maintaining user privacy and offline functionality.
Responsive Live Camera Experience
Delivering a fluid scanning experience with instant visual feedback, real-time text highlighting, and interactive actions without interrupting camera performance required careful UI rendering and resource management.
