Free Claim Evidence Matrix
Compare what different sources say about a claim by organizing excerpts, your assessment, and the questions that remain.
How to use it
Write one specific claim, add a source for each relevant excerpt, and record whether you think it supports, contradicts, partly addresses, or does not clearly address the claim. Include dates and context in your notes.
What this does not do
This tool does not verify sources, judge source quality, or decide whether a claim is true. The evidence assessment is yours; check original sources and consider missing context.
