A literature review matrix, built from the full text of every paper
Pick two to four papers and CruxDoc reads each one end to end, then lays them side by side facet by facet: question, method, sample, findings, limitations, conclusion. Every cell is a quote checked against the paper before it reaches you.

How it works
Upload the papers
PDF, Word, or scans read with OCR. Two to four papers per matrix.
Pick them in the Research workspace
Tick the papers and run Literature matrix. Each is read in full, not sampled.
Read the table
Papers as columns, facets as rows. Where papers disagree, the row says so.
Verify in one click
Every verified cell links to its page in the reader. Anything unverified is labelled.
Every cell is a quote, and every quote is checked
A review table is only worth the citations under it. CruxDoc string-matches each quoted cell against the paper's text on the server, so a finding that is not in the paper cannot appear as if it were. A quote that fails the check is shown as unverified rather than hidden.
Need the numbers behind a row? The paper snapshot and methods extraction read the same papers one at a time, and the reference list exports as BibTeX for the bibliography.
Frequently asked questions
Q.01What does the AI literature review produce?
A matrix: two to four papers as columns, the facets a literature review runs on as rows - research question, method, data and sample, key findings, limitations, conclusion. Each cell quotes the paper it belongs to and links to the page the quote is on.
Q.02Does it read the whole paper or just the abstract?
The whole paper, every page. The matrix is built from full text, so a limitation buried in the discussion section lands in the table, not just what the abstract chose to say.
Q.03What happens when the papers disagree?
The matrix says so, per facet, instead of averaging them into one sentence. Disagreement is usually the most useful row in a review, and hiding it is the failure this tool exists to avoid.
Q.04How do I know a cell is really in the paper?
Every quote is string-matched against the paper text on the server before you see it. Verified quotes link to their exact page; anything that cannot be matched is labelled unverified instead of dressed up as evidence.
Q.05Is it free?
Your first document needs no account. The literature matrix lives in the Research workspace of a free account, which includes 100 questions a month; each matrix uses one, and every run is kept in your history to reopen free or share as a page.
