◉ Processed on this computer. Your PDF is never sent to a service.
Local PDF copies, rendered pages, diagram crops, saved corrections, and generated previews.
PDFs you imported from other folders and HTML books already downloaded elsewhere are unaffected.

GoBookz renders every page and searches for regular Go grids. You can cancel and resume.
Compare positions with the source. Correct stones, crop boundaries, board size, labels, or move sequences. Confidence scores are heuristics; they are not measured accuracy.
One small file contains converted text and interactive vector boards, without original scans. Open it directly in your browser, even after closing GoBookz.
Some diagrams will be missed or need correction. Source pages stay in the editor for comparison. Check converted text and diagrams before exporting. Ambiguous move order stays a position to explore.
