From papers to evidence to argument to manuscript
Carrel turns the papers you have collected into a living structure of claims, evidence, counter-evidence and manuscript sections. See what supports each claim, where the literature disagrees, and trace every idea back to the exact passage before it reaches your manuscript.
Carrel does the organising that makes the argument easier to see. The argument stays yours.
Papers in, chapters out — and Word goes both ways
Finding the papers is the part that works. The hard part comes after: seeing how they fit together, and knowing what to write next. The papers are read, the page is still blank, and nobody shows you the step in between.
01 · Read what matters
02 · Make sense of the literature
03 · Write from the evidence

Bring your whole Zotero library across with its collections, drop in PDFs, or paste a DOI or arXiv id. Three hundred papers become one working set: parsed, enriched from Crossref and OpenAlex, and ready to read, search and cite.

01Read what mattersReading and annotating
Highlight in four colours, keep notes on the page, and ask for an explanation of any passage in the context of the paper. The queue remembers where you stopped and tells you how long is left.
01Read what mattersAsking the papers
Answers come only from papers you imported. Every sentence carries a citation, and clicking it opens that paper at the passage. Nothing is asserted without a source, and when the evidence is not there, you are told so instead of guessed at.
02Make sense of the literatureAgreement and conflict
Claims, methods and findings are pulled out of your papers with their exact quotes, linked by citation and by what they support or contradict. When you draft, those disagreements come through as contrast — “however”, “in contrast” — instead of a list. The gaps between them are flagged, which is where a contribution usually is.
02Make sense of the literatureThemes and structure
Carrel proposes the sections — background, what the field agrees on, where it contradicts itself, where the gap is — and fills each one with the claims and saved answers behind it. Rename them, merge them, throw out what is wrong. It is the synthesis matrix your supervisor keeps asking for, arriving filled in instead of blank.
03Write from the evidenceDrafting and citing
Pick a section and Carrel drafts it from your passages only, arguing where your papers disagree. A citation is a live link to a page, not text you typed — so when your paragraph moves away from what the source actually said, Carrel flags it. Cite in APA, MLA, Chicago, IEEE or Nature.
03Write from the evidenceHanding it over
Export a real .docx whose tracked changes open as tracked changes in Word, attributed to the right person. They mark it up the way they always have and send it back — nothing to install, no account, no new tool to learn. Markdown, LaTeX and BibTeX come out too.
Answers are built only from papers you imported. Click a citation and the paper opens at that passage — so you are never taking the assistant’s word for anything.
Where do these papers disagree about the masking rate?
Both mask 15% of tokens, but BERT fixes the mask during preprocessing, so the same positions are predicted every epoch. 1RoBERTa keeps the rate and re-samples the mask each epoch, and reports that the static mask costs accuracy downstream. 2
Where Carrel begins
Search engineshelp you discover research.
PDF assistantshelp you understand one paper at a time.
Writing assistantshelp you generate prose.
Carrel connects the work in between: deciding what the literature actually supports, constructing your claims, resolving contradictions, and turning that reasoning into a manuscript.
