On-device AI

Remove image background locally

Remove backgrounds locally with a fast portrait model or a finer general model, then reuse the mask with transparency, a solid colour, or another image.

Image to text (OCR)

Recognise Simplified Chinese, Traditional Chinese, or English text locally and export readable text plus structured JSON with confidence data.

Document photo scanner

Detect and refine page corners, correct perspective, apply colour, greyscale, or black-and-white enhancement, and optionally combine pages into a PDF.

Upscale image

Use local Real-ESRGAN inference to double image width and height; the verified model is cached after its first download and the page shows the current device limit.
