The problem

OCR output is only useful if someone can see where it went wrong, but most tools hand back a plain text dump. Tuning OCR for faded scans, phone photos or handwriting is guesswork.

What I built

I built a local Flask web app that runs PaddleOCR on an uploaded document and shows the page and the extracted text linked by position, with confidence-colored boxes. A short document clue seeds the settings, and the accepted result exports as structured Markdown.

How it works

  1. Upload a PDF or image and add an optional clue.
  2. The clue sets the first-pass OCR settings.
  3. Review the page and the text side by side.
  4. Tune any of 22 settings and re-run.
  5. Fix characters inline and export Markdown.
How OCR Review Studio is wiredRuns locally in a Flask app on the PC. Nothing is uploaded anywhere.
