PDF2PPt Study turns scanned / image-only slide PDFs back into editable PowerPoint.

Lecture slides often arrive as scanned or image-only PDFs: there's no text to select, so you can't fix a typo, update a title or reuse a bullet. Chat-with-PDF tools only read your slides; PDF2PPt Study rebuilds them. Every page becomes a real .pptx slide with editable text boxes placed where the original text was, on a background with the old text cleanly removed, with figures and diagrams kept as images and speaker notes on every slide.

How it works
- PyMuPDF renders each page; Meta Muse Spark Open on Baseten reads the page image and returns each text block with its position and style.
- OpenCV inpainting / flat fill removes that text from the background; figures stay as images.
- python-pptx writes editable text boxes on top, plus speaker notes (summary, key points, key terms).
- Runs on Modal behind FastAPI with an access code, rate limits and a daily spend cap.

Bonus study tools (from the same analysis): per-slide notes and a course outline, flashcards with Anki export, a quiz that explains each answer, and Q&A with slide citations.
