Why use AI Aware’s Legal Text Detector?
Check whether legal writing was created by artificial intelligence and validate references
AI legal text detection
AI-hallucinated case law is starting to cause problems for a wide range of legal professionals. The problem first gained widespread attention in the US case of Mata v Avianca (2023), where attorneys relied on fabricated cases generated by ChatGPT, resulting in court sanctions and significant reputational damage. The UK and other countries have seen their own incidents – by August 2026, nearly 2,000 court decisions involving AI-hallucinated content had been recorded worldwide in Damien Charlotin’s AI Hallucination Cases database.
The only AI detection tool that validates UK case law
Detecting AI-generated text is only half the problem for law firms. The other half is confirming that the cases being cited actually exist and say what they are claimed to say. AI Aware is the only AI detection platform that combines content detection with direct reference validation against authoritative UK legal databases, including BAILII – the definitive repository for British and Irish case law – and official Government and tribunal case law publications.
The hidden risks of AI-generated legal documents
AI generator tools are being used to draft contracts, witness statements, skeleton arguments, pleadings and legal opinions in seconds. Increasingly, those documents are finding their way into legal proceedings without disclosure. The risks are that AI language models are known to fabricate case citations, misstate precedent and generate plausible-sounding but legally inaccurate arguments.
For a law firm, submitting a document containing hallucinated case law (even unknowingly) can result in sanctions from the court, damage to professional reputation and, in the most serious cases, disciplinary action from the Solicitors Regulation Authority or Bar Standards Board. AI Aware’s detection tool helps firms build a systematic check into document review workflows, so that any AI-generated content is identified before it reaches counsel, a client or a court.
Visualisation tool
AI Aware’s visualisation tool shows the AI-generated legal text detected and whether it occurs in blocks or is dispersed. This allows you to contextualise the findings and understand the significance of AI-generated output.
Other systems give an overall percentage, which is difficult to understand. Our AI text detector goes beyond this and grades each section of text as AI or human generated legal content, showing its consistency with either so that you can get an overall view of a document.
Benefits of AI text detection & reference checking for legal firms
For legal firms, our AI text detector allows you to identify AI-generated content with a high degree of accuracy. We have tested with law firms using large quantities of varied output to keep false positives low: in our published tests, only 1.16% of human-written texts were wrongly flagged. This means that you can be confident of using our product and won’t be falsely accusing use of AI.
Our reference checker is able to identify misstatements of law and offer corrections.
It isn’t included in the 3 free checks, so contact us for a free trial.
Why use AI Aware’s legal text and reference checker
Findings you can explain
AI Aware provides robust scientific percentages and identifies exactly which paragraphs in a legal document are AI-generated, giving you specific, defensible findings rather than a single percentage that is difficult to act on or explain to a court.
Detects hallucinated case law
Unlike general-purpose AI detectors, AI Aware includes reference checking that flags misstatements of law and fabricated citations, the exact failure mode that has led to court sanctions against law firms using AI-drafted documents.
A closed secure system that can process sensitive documents
AI Aware uses our own models with secure and encrypted network architecture. Unlike some other providers, this means that our system is appropriate for handling confidential or sensitive documentation.
Catches “humanised” AI content
Many AI detectors are easily fooled by text that has been post-processed through humanisation tools. We have specifically trained our system to detect these manipulations, which are increasingly common in legal contexts where parties may be motivated to conceal AI use.
Built for low false-positive environments
In legal and regulatory settings, a wrongful accusation carries serious consequences. AI Aware publishes its false positive rate and full test method, so firms can judge the evidence for themselves before acting on a finding.
Proven AI-generated content detection
AI Aware’s legal text detector combines machine learning with other statistical methods to tell AI-written legal text from human drafting.
It looks at signals such as reasoning, linguistic structure and how arguments are built, and shows which passages in a brief, letter or submission were flagged.
For law firms, we are the only company combining AI legal text checking with reference validation.
