LexGPT is the verification layer for AI-assisted legal work. Every citation checked, every clause traced to a source, every draft signed off by a human — before it reaches a client or a judge.
Written for solicitors, barristers and in-house counsel, not engineers. Nothing assumed.
2 min readClients now arrive with AI-drafted documents. Courts impose sanctions for invented authority. The differentiator is no longer who can generate the fastest — it is who can stand behind every line.
Each authority verified as existing, current, and standing for what it claims — with the pin cite and the date.
Each clause traced to the precedent, statute or instruction it came from, so the file is auditable.
A named lawyer reviews and approves. Nothing leaves the firm as an unreviewed AI output.
Citations to judgments that do not exist. Sanctions, embarrassment and costs.
A real case cited for a proposition it never decided.
Overruled or superseded authorities, or a rule that changed last month.
A US doctrine smuggled into an English or EU matter.
Privileged material pasted into a public model. Waiver risk.
A firm recommendation with a caveat buried or missing.
A drafted clause that quietly changes the deal a client agreed.
Every one of these is caught by the same routine — taught in the free handbook.
The mindset, the seven failures, the four-file harness, a full worked example and a glossary — about forty minutes, in plain English.
Every claim in a legal document is either authority you can cite or your own reasoning. Never let the second wear the costume of the first.
