What does Wexler AI do?
Wexler is a legal AI platform that extracts, analyses and verifies factual information from large case document collections. It is used by litigation teams to build chronologies, surface inconsistencies and flag false testimony as hearings proceed.
Why is Wexler AI useful?

Specialised, purpose-built AI
Law firms favour AI built specifically for litigation over general-purpose models.
This can cut tasks like chronology building from days to hours.
Real-time courtroom assistance
Real-time tools now flag inconsistencies during hearings and depositions.
That helps lawyers challenge inaccuracies as testimony happens.
Data privacy, security and regulation
Sensitive client data raises privacy and compliance concerns, especially under GDPR.
Firms need strong encryption, access controls, and audit trails to reduce risk.
