PDF Extract — User-Defined Evidence Tables

Overview

The free analog of Elicit's "columns" feature. Point it at a stack of PDFs, declare the columns you care about, and get back a tidy evidence table — one row per paper, one column per question — as CSV or a Markdown table. Built for data extraction across a corpus: literature screening, methods comparison, PICO/sample-size pulls, and review evidence sheets.

Every input is normalized to clean Markdown via Microsoft MarkItDown (see the alterlab-markitdown skill) before any column is extracted, so PDF, DOCX, PPTX, HTML, and the other MarkItDown formats all work.
