paperparse
figures, tables & captions from any paper
Scientific PDF → structured output

Every figure, table and caption, mapped.

Drop a paper. paperparse returns each figure as a hi-res crop with its caption — sub-panels and their sub-captions included — every table transcribed to markdown, and the body as clean markdown. Then it checks its own work and flags anything it can't verify.

Pipeline

Three passes, one clean map.

Body text and figures are extracted by the tools each is best at, then a validation stage reconciles the two so nothing ships silently wrong.

01 · OCR

Mistral reads the text

The full body is transcribed to markdown — headings, tables and math preserved — and every figure legend is captured wherever it physically sits.

02 · Vision

Gemini finds figures & tables

Each complete figure is detected as one region, re-rendered at 300 dpi and paired with its caption; with sub-panels on, every labelled panel is cropped and its sub-caption sliced. Tables are detected the same way and transcribed cell-by-cell to Markdown — uncertainties (even asymmetric error bars) preserved verbatim.

03 · Validate

It checks its own work

Off-page captions are relocated by label, a missed figure is re-detected and recovered, and anything still unresolved is flagged — never dropped in silence.
