EvidenceGrid
AI literature review matrix

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.

Start free with 10 papers each month. Google sign-in uses your email and basic profile only to create and secure your EvidenceGrid account.

Built around the part AI tools make you redo.

EvidenceGrid keeps the answer and the source together, so checking a claim takes one click instead of another search through the PDF.

In a fixed 11 paper production acceptance test completed in July 2026, EvidenceGrid processed 11 of 11 supported PDFs and achieved 98.86% quote and page accuracy after repair. All 4 repair attempts succeeded, with 0 severe fabricated synthesis claims. Results apply only to this test set. Read the method and limits.

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.
