Could you build this?
Partial Building an annotation canvas UI is straightforward, but robustly segmenting complex PDFs into discrete text, tables, figures, and LaTeX equations requires specialized vision-document parsing models.
What it would actually take: The frontend can use PDF.js and canvas manipulation libraries. However, the core segmentation engine requires advanced multimodal document layout analysis models (like LayoutLMv3, Marker, or Nougat) running on GPU inference infrastructure to accurately extract bounding boxes for tables and math equations without degradation across varying multi-column document formats. A solo builder can prototype with Claude Vision or GPT-4o, but a production tool demands dedicated CV/OCR pipelines and low-latency document-tiling workers.
