# Citation Checker: Verify Every Source Before You Submit Source: https://zentor.ai/use-cases/citation-checker Upload the deck, paper, or report you are about to send and get every citation opened, every number traced, and a corrected file back with a change log. ## Prompt ```text Check every citation and number in the attached deck. Open each source, tell me where it does not support the claim, and give me back a corrected file with a change log. ``` Variations: - **Paper before submission**: Check the references in my paper: flag anything that is broken, retracted, or does not actually support the sentence citing it, and suggest a working replacement where one exists. - **Check against my own data**: Verify the figures in this deck against the spreadsheet I attached, not against public sources, and flag every number that does not match the sheet. - **Just the verdict**: Audit the citations in this document and give me a list only: claim, source, verdict, and reason. Do not rewrite anything yet. ## How it works 1. **Upload What You Are About to Submit**: Drop in the deck, paper, or report. Attach the internal documents your numbers came from if you have them, so private figures can be checked too. 2. **Zentor Audits Every Claim**: Each citation is opened and read, each number traced. Unsupported claims, broken links, and contradictions get flagged with the reason, not just a warning icon. 3. **Download the Corrected Version**: You get back a fixed file with sources attached and a change log. Review the diffs, then send it. ## What gets checked - Whether the source supports the claim: A reference that exists but says something else gets flagged the same as a broken one. That is the error that costs you in review. - Broken and moved references: Dead links, retracted papers, and sources that moved are surfaced, with a working replacement suggested where one exists. - Numbers against your own documents: Attach the spreadsheet and the figures in the deck are checked against it, for the numbers no public source can confirm. - Slides, not just essays: Most citation checkers only read prose. Decks and reports are where an unsourced number actually costs you. - Contradictions inside one document: The same metric quoted two ways on two slides gets caught before a reader catches it. - Fixes, not just flags: The corrected file comes back with the wrong number replaced, the citation repaired, and a log of exactly what changed. ## Comparison | Feature | Checking by hand | Format checker | Zentor | |---|---|---|---| | What is actually verified | Whatever you have time to reopen | Citation formatting and style | Whether the source supports the claim | | File types | Any, slowly | Papers and prose | Decks, reports, and papers | | Private figures | Cross-checked manually | Out of scope | Checked against the documents you attach | | Broken links | Found by clicking each one | Flagged | Flagged with a replacement source where one exists | | Output | Notes to yourself | A list of warnings | A corrected file plus a change log | ## FAQ ### What is a citation checker? It verifies the sources and numbers in your work. Zentor opens each citation, compares it against the claim it supports, and returns a corrected version of your file with a change log. ### Can it check citations in a PowerPoint, not just papers? Yes. Decks and reports are handled the same way as papers, which matters because a deck is usually where an unsourced number ends up in front of a client. ### Does it verify that the source actually says what I claimed? Yes. That is the point. A reference that resolves but does not support the sentence citing it is flagged with the reason, not just marked as reachable. ### What citation formats are supported? Common academic formats and plain inline references both work, because the check is on the source behind the citation rather than on its punctuation. ### Can it check numbers against my internal data? Yes. Attach the spreadsheet or report your figures came from and each number in the document is compared against it, for the claims no public source can confirm. ### How does it fix a problem it finds? You get a corrected file back: the wrong number replaced, the citation repaired or swapped for a working source, and a change log showing what was touched and why. ### Is my document kept private? Yes. Your document stays in your own workspace and is used only to run the check and produce the corrected version. ### Is there a free citation checker to try? The free tier lets you run a check on one deck or paper before moving to a paid plan for higher volumes.
