EvidenceGrid turns research PDFs into a literature review matrix you can verify.
Upload selected research PDFs, define custom extraction fields, and compare papers in one matrix. Every result keeps the exact quote, page, match status, and a path back to the original PDF.

What is an AI literature review matrix?
An AI literature review matrix organizes comparable evidence from multiple papers into structured fields. EvidenceGrid keeps each extracted answer linked to its exact quote, page, match status, and source PDF so researchers can verify the matrix before synthesis or export.
From PDFs to a matrix you can defend.
Keep the workflow focused on the research question, the extraction fields, and the evidence behind each result.
Define the review
Create a focused workspace, enter the research question, and choose a template or up to twelve custom extraction fields.
Extract the matrix
Upload research PDFs or import RIS, BibTeX, and CSV references. Background jobs populate one comparable row per paper.
Verify the evidence
Review exact quotes and pages, repair uncertain fields, open highlighted source pages, and generate evidence-linked cross-paper items.
Reuse and deliver
Save extraction templates, copy workspace structures, download PDF, Word, Excel, or Obsidian files, or send reviewed evidence to Zotero and Notion.
A matrix shaped by your question.
Use built-in templates or define fields with their own extraction instruction and evidence requirement. Save the structure for another review without copying papers or results.
Review at the source
Matched quotes, claimed pages, highlighted source views, and single-field repair keep uncertainty visible.
Move the result once
Download PDF, Word, or Excel files, create an Obsidian note, or send verified evidence to Zotero and Notion.
