A stamped report per reference, with the exact reason behind every flag. Export as PDF or CSV.
Meanwhile, in the stacks
Between paste and verdict, every reference triggers its own search across the whole catalog. Here is one fabricated citation being hunted down, in real time.
Anatomy of a flag
No black-box scores. When a reference gets flagged, the report marks exactly which field failed and against which record, so you can fix it in one edit.
Both names confirmed against the author record, including ORCID where available. 2 of 2 verified
The paper exists, but it was published in 2022. A one-digit slip that most reviewers will still circle. 2021 → 2022
No journal by this name in any index. The real paper appeared in a conference proceeding, a classic AI-paraphrase artifact.
The prefix belongs to a different publisher and the suffix returns nothing. EssayTone suggests the correct DOI from the matched record. fix suggested
The flag taxonomy
Fabrication is only the loudest failure. Most bibliographies fail quietly, in ways a spellchecker never sees.
Plausible authors, confident formatting, zero matching records anywhere. The signature failure of AI-assisted writing.
Right paper, wrong people: missing co-authors, mixed-up initials, or an author borrowed from a similarly titled work.
The paper is real but has been withdrawn. Citing it uncritically is a red flag for any editor. Checked against Retraction Watch daily.
Identifiers that never resolved or stopped resolving. EssayTone tests every one live and proposes the correct identifier when a match exists.
Off-by-one years, swapped volume and issue numbers, preprint dates cited as publication dates. Small, common, and correctable.
Journals with predatory patterns: no indexing, no review record, hijacked titles. Cited knowingly is one thing; unknowingly is another.
Follow your reference list through extraction, correction, monitoring, and export — from pasted bibliography to attached record.
Upload the whole PDF. EssayTone sweeps the document, finds the bibliography wherever it lives, and lifts every reference out, including footnotes and in-text citations.
When a field disagrees with the matched record, the report shows the correction inline, in your citation style. Accept it with one click or copy the corrected entry.
A citation that was fine in March can be retracted in September. Save a reference list and EssayTone re-checks it daily, telling you the moment a paper’s status changes.
The final report carries the seal: every reference listed with its verdict, evidence and check date. Attach it to a submission, hand it to your advisor, or keep it for the record.
Why it matters now
AI writing assistants invent plausible-looking citations. Reviewers, editors and advisors are checking for them. Whichever side of the desk you sit on, run the check first.
If you're writing
A bibliography with even one unverifiable entry invites a desk rejection or, worse, a misconduct inquiry. “Check ref. 14, this doesn't resolve” is a comment you never want to receive. Stamp everything before submission and it never arrives.
If you're reviewing
Approving a paper whose references were never checked puts your name next to the mistake. Screen every submission's reference list in seconds and spend your review time on the science instead.
If you're teaching
Students lean on AI tools that fabricate sources with confident formatting. Run submissions through EssayTone and turn each flag into a teaching moment, before the habit hardens into misconduct.
If you're editing
Citation fraud is the hardest thing to catch by eye at scale. Filter fabricated references at initial screening and keep the review pipeline for work that deserves it.

A thesis runs to hundreds of references and checking them by hand is unrealistic. EssayTone verified my whole bibliography in one batch and caught several citations that did not exist at all. It saved me from being caught by my own reviewers.
I run every student submission through it. Within minutes it surfaces citations that don't hold up or are outright fabricated. In an age where AI writing is everywhere, this kind of verification is how I uphold rigor without burning evenings on it.
As a journal editor, citation fraud is the hardest thing to catch by hand across a huge submission volume. EssayTone lets me filter out manuscripts with bogus references at first screening. It's now standard equipment in our editorial office.
