thanks to Codex, it now uses a YOLO detector running using ONNX to detection regions in each rendered PDF page image (text, pictures, formulas, tables).
based on this analysis, PDF Reflow then cuts out TEXT regions into tiny little word images and adds back the original text from the PDF (when available) so you can still select and find text in the reflowed HTML render.
Hope you find this useful.
The original version used heuristics, but frankly it was breaking on many more PDF that I'd want to admint.
This new AI-based version that uses a YOLO detector trained specifically on Doc Layout dataset seems to do a very very good job.

Converted to ONNX of course, and also CoreML for the iOS app. I haven't yet tried on Android. Does it work for you if you have an Android phone?
I notice some inconsistent behavior with the placement of footnotes sometimes occurring inline with the text. That's kind of a tough edge case.
