Prizmo Go 4.0 is an important update that brings major improvements to text processing (OCR), rich interactions, as well as optimization for iOS 16 & important bug fixes.

Prizmo Go is the reference app for effective text grabbing on iOS that will give you a significant upgrade over the built-in Live Text feature for when you need it, in terms of covered languages (139 vs. 8), handwriting, recognition accuracy, AI-based translation, text selection experience, and interaction/sharing capabilities.
