Chrome Screen AI Library

Purpose

Chrome Screen AI library provides two on-device functionalities for Chrome and ChromeOS:

• Main Content Extraction: Intelligently isolates the main content of a web page, improving its readability by stripping distracting elements (based on the accessibility tree).
• Optical Character Recognition: Extracts text from image.

These functionalities are entirely on device and do not send any data to network or store on disk.
