Catch the citation errors in your thesis before your supervisor does.
Cross-checks every citation in your Google Docs, Overleaf, or Word Online document in 30 seconds. Flags orphan citations, unused references, and broken DOIs.
Your document is never sent to our servers or any third party.
The 11pm-the-night-before-submission problem
Your thesis is due tomorrow. You have 247 references. You cited maybe half of them in the text. Some of the in-text citations don't seem to match anything in your reference list. You're about to spend the next four hours cross-checking by hand.
- Hours of manual cross-checking — comparing every
(Smith, 2024)against a 50-page reference list, with a paragraph in between to lose your place. - One of the most common reasons for desk rejection — orphan citations and missing references signal sloppy work to peer reviewers and committees.
- Pre-submission anxiety — that nagging "did I miss something?" feeling that doesn't go away until someone has signed off on the manuscript.
How it works
Open your document
Works inside Google Docs, Overleaf, or Word Online — wherever you're already writing.

Privacy & Trust
- Your document is never sent to our servers or any third party.
- No AI. No data collection beyond your license key.
- Permissions are scoped to three specific editor domains — Google Docs, Overleaf, Word Online. Nothing else.
- License validation only ever sends your license key. Never your document content.
For Google Docs specifically, we read your document via Google's own plain-text export endpoint — your data round-trips inside Google and never reaches us. Read the full privacy policy.
Built by Dr. Rafiq Muhammad, PhD — author of the Mastering Research book series.

Frequently asked questions
Will my document content be uploaded anywhere?
No. For Overleaf and Word Online, the extension reads your document text directly from the browser — it never touches our servers. For Google Docs, because the modern Docs editor renders text to a canvas (not the DOM), we use Google's own plain-text export endpoint: your data round-trips inside Google and never reaches us or any third party. See the full privacy policy for details.
Which citation styles are supported?
Vancouver (numerical), APA (author–year), Harvard (author–year, no comma), Chicago (footnote), and IEEE (numerical) in v1. The auto-detector picks the right style for most documents; if it's ambiguous, you pick from a dropdown. Additional styles will be added based on user requests.
Does this work offline?
Yes for the citation check itself — all parsing and matching happens locally in your browser. License validation requires occasional internet (every 7 days) but has a 7-day grace period if you're offline.
Can I cancel anytime?
Yes. Both monthly and annual subscriptions are cancellable at any time via the link in your account email or by contacting support@gradsummit.com. You keep access until the end of your current billing period.
What if I find a bug?
Email support@gradsummit.com — replies go to a real human (the developer). Most bug reports get a response within 24 hours.
What's coming next?
Citation Gap Finder is the first in a planned set of browser extensions for academic writing — Manuscript Version Vault, Reference List Sanity, and others under the GradSummit umbrella. See the Tools section on the homepage for the latest.
