EvidenceGrid is an AI assisted literature review workspace for graduate researchers, academic staff, educators, and evidence review teams. It turns selected research PDFs into a structured literature review matrix while preserving the exact supporting quote, claimed page, match status, and a route back to the highlighted source. Users can define custom extraction fields, review or reextract individual cells, generate auditable themes, agreements, disagreements, limitations, and research gaps, then export reviewed evidence to PDF, Word, Excel, Obsidian, Zotero, and Notion.
