Text Detection API Link copied!

The Text Detection API enables web applications to detect and recognize text within images, video frames, canvas elements, and camera streams. As part of the WICG Shape Detection API family, it exposes a modern asynchronous interface (TextDetector.create() and detect()) that returns recognized text along with enclosing bounding boxes and oriented corner coordinates. This provides web developers with fast, zero-payload optical character recognition directly within the browser while keeping user image data private.
