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 export the matrix when it is ready.
A matrix shaped by your question.
Use built-in templates or define fields with their own extraction instruction and evidence requirement. Evidence stays attached when the schema changes.
Review at the source
Matched quotes, claimed pages, highlighted source views, and single-field repair keep uncertainty visible.
Synthesize after review
Generate themes, agreements, disagreements, limitations, and gaps from verified cells.
