OCR Review Studio
Upload a scan, check OCR line by line, tune it, export Markdown.
Built for: Someone digitizing a scanned document, such as a handwritten parts list





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
- Upload a PDF or image and add an optional clue.
- The clue sets the first-pass OCR settings.
- Review the page and the text side by side.
- Tune any of 22 settings and re-run.
- Fix characters inline and export Markdown.
