For UK law students
Verify with Quill
Paste your essay or a ChatGPT answer. Quill checks every case you cite against a verified corpus of UK judgments, flags what it can't confirm, and gives you grounded tutor feedback — the kind of read you'd get from a sharp supervisor, in seconds.
Why it matters
AI invents cases. That gets people caught.
Every law student now uses AI to draft and check work — and AI confidently makes up case names, citations, and holdings that look completely real. Lawyers have been sanctioned for citing cases that never existed. In an essay or a problem question, one fabricated authority undermines the whole argument. Quill is the layer that catches it before your marker does.
How it works
Three steps, a few seconds
- 1
Bring your work in
Paste your essay or a ChatGPT answer, drag in a PDF or Word doc, or just speak — Quill takes it however it comes.
- 2
Quill checks every authority
It extracts every case and citation and checks each one against a verified corpus of UK judgments — separating what it can confirm from what it can't.
- 3
You get a grounded read
Per-citation verdicts plus tutor-style feedback on your argument, your use of authority, and how to make it stronger — grounded only in real cases.
What Quill catches
Unverifiable citations
Every case you cite is marked verified or couldn't-verify, so you know which authorities to trust before you rely on them.
Misused authority
Where Quill has a case's ratio on file, it checks whether you've actually used the case for what it decided.
Weak argument & structure
A demanding tutor read: where your reasoning is thin, where authority is missing, and how to tighten it.
The promise
We'd rather say “couldn't verify” than guess.
Quill never invents a case or a holding, and it never calls a real citation “fake”. If a case isn't in our verified corpus, it says so plainly and tells you to double-check — because a confident wrong answer is exactly the problem we're solving. That restraint is what makes the green ticks mean something.

Questions
Frequently asked
What does Verify with Quill do?
You paste an essay or a ChatGPT answer (or drag in a PDF or Word doc). Quill pulls out every case and citation you've used, checks each one against a verified corpus of UK judgments, and gives you grounded tutor-style feedback on your argument and structure.
Will it catch fake cases that AI made up?
It flags any citation it cannot confirm against our corpus and tells you to double-check it exists. We never label a citation 'fake' — our corpus is large but not complete, so we're honest about the difference between 'verified' and 'couldn't verify'. That honesty is the point: you find out which authorities you can rely on.
Is it free?
You get 3 free checks. After that, unlimited verification is part of a paid plan. No card needed to start.
Can I upload PDFs or Word documents?
Yes. Drag in a PDF, Word (.docx), or text file and Quill extracts the text for you. You can also type, paste, or speak using the voice button.
Does it remember my work?
Every check is saved to your private study space, and Quill uses your past work for continuity — so it can notice a mistake you keep repeating. Your materials are yours.
Is this a substitute for checking my own work?
No. Quill is a fast, rigorous second pair of eyes — it catches unverifiable citations and weak use of authority. You should still read the cases yourself; Quill helps you know which ones to trust first.
