Pilot5 launched a standalone legal AI service that uses five frontier models to analyze lawyers’ questions, challenge a developing consensus and deliver one recommendation with its supporting sources and strongest counterargument. The service creates a structured brief covering the lawyer’s side and goal, reason for asking, jurisdiction, legal context, deadlines, constraints, known or decided matters, and facts or assumptions that could materially change the analysis.

The five models first analyze the matter separately. Lawyers can read each first-round analysis as it arrives, before the models see one another’s work. The models then critique each other anonymously and revise their positions. One model, called the Contrarian, is assigned to attack the emerging consensus and find legal authority against it. The final synthesis gives one recommendation, its sources and the strongest counterargument, which Pilot5 retains on record.

Pilot5 said a complex deliberation typically costs about $7 and takes about fifteen minutes. Its Statutory Review costs $0.50 and checks employment agreements clause by clause against potentially applicable federal requirements, including OWBPA/ADEA, FCRA, DTSA and the Speak Out Act, as well as the selected state’s law. At launch, it covers eleven states and the District of Columbia. Each requirement is labeled satisfied, partial, needs review or missing, with relevant statutory or regulatory text quoted from an official source; it says when text could not be retrieved. Contract Understanding, priced at up to $0.20, identifies the function of each numbered contract clause while preserving the original wording.

Pilot5 said it does not use client files to train models. Zero Data Retention mode for deliberations and a data processing agreement are available on request. Co-CEOs Wilfrid Rimbault and Thomas Wainstein said the service aims to put the other side’s strongest argument and its supporting authority before lawyers commit to a case.

The report notes that legal technology companies already use multiple models to answer complex legal questions, including systems in which one model challenges another. It describes Pilot5’s service as a distinct, structured standalone option that may appeal to lawyers who want models to debate explicitly and prefer a lighter, more economical service over a larger legal AI platform.
