Built a tool that maps research gaps from PDFs — beta, would love ML researchers to break it

Summary

The author introduces Papira, a beta tool that analyzes uploaded research papers to map coverage and identify gaps in machine learning and NLP subfields.

I built Papira to solve my own problem: understanding where a subfield stands before writing a paper. Upload 3 papers from an area you're studying. It builds a coverage matrix (problems, approaches, benchmarks, and where the gaps are) across all three papers at once. Beta, so it's not perfect. Works best on empirical ML/NLP/systems papers. Full refund if it fails to produce a result.
