Pilot5 Legal went live on October 5 at legal.pilot5.ai. It is Pilot5 for lawyers: a dedicated console, built first for US practice, that runs inside the AI assistants lawyers already use. This post says what it does, what it costs, and what it does not do.

The idea in one line

A lawyer should not hear the other side’s best argument for the first time in court. Pilot5 Legal puts that argument in front of them before they commit, with the authority alongside it.

We call it mooting your case. Five frontier AI models work the matter separately. One of them, the Contrarian, is assigned to challenge the emerging consensus and to find the authority that cuts against it. The lawyer gets one recommendation, the sources behind it, and the strongest counterargument preserved on the record. The lawyer remains responsible for the decision.

How a deliberation works

It starts with the brief, not the answer. Before any model analyzes anything, the Pilot5 Companion builds a structured understanding of the matter: which side you represent, what you are trying to achieve, why the question is being asked, the jurisdiction and legal context, deadlines and constraints, what is already decided, and the facts or assumptions that could change the analysis. You approve the brief. Then it runs.

Five models, first round, no contact. Each model analyzes the matter independently, from its own angle, without seeing the others’ work. You can read each first-round analysis as it lands, and you see where the five agree and where they disagree before any convergence.

Then they argue. The models critique one another’s analyses without knowing which model wrote them, respond to objections, and revise their positions under challenge.

Then they converge. The final synthesis gives one recommendation, its supporting sources, and the strongest remaining counterargument, kept on the record. Every claim is marked sourced or inferred, so you see at a glance what to verify before you rely on it.

The cost of every run is shown before it starts, and unused credits are returned.

It runs where you already work

Through the Model Context Protocol (MCP), a deliberation can be started from Claude, ChatGPT, Perplexity, Microsoft Copilot Studio, Mistral Le Chat and Cursor, as well as from the console itself or through a REST API.

There is no new platform to adopt. The assistant you use every day becomes the door to a five-model deliberation, and the recommendation, the sources and the opposing argument come back where you asked the question. Setup takes a few minutes: pilot5.ai/docs/mcp.

Four tools around the deliberation

Statutory Review, $0.50. Paste an employment agreement, such as a separation agreement, and choose the side you represent. It is read clause by clause against the applicable federal requirements and restrictions, including the OWBPA/ADEA, FCRA, DTSA and the Speak Out Act, together with the law of the selected state (eleven states and the District of Columbia at launch). Each requirement is marked satisfied, partial, needs review or missing, with the statutory or regulatory text quoted from an official source. Where the text could not be retrieved, the review says so.

Contract Understanding, up to $0.20. Identifies what each numbered clause in a contract does, in the order it appears, while keeping the source wording intact. Any contract type.

Statutory Authority Lookup, free. Paste up to 25 statutory and regulatory citations and get the enacted text directly from the official publisher, with the source link and the retrieval date. No generative model is used. An unresolved citation is shown as unresolved.

Firm Playbook, free. Add your firm’s own approved positions to the statutory baseline used in future statutory reviews. Nothing affects a real review until a person has approved it.

Built first for US practice, not limited to it

The five workflows of the console check against US federal and state law. The deliberation engine and its source base are not limited to the United States. Statutes, regulations and case law come from official publishers and established legal repositories, including:

  • United States: Congress.gov, CourtListener, the Federal Register and more than twenty state legislatures.
  • United Kingdom: legislation.gov.uk and BAILII.
  • Canada: CanLII.
  • France: Légifrance, Judilibre, Conseil d’État, Conseil constitutionnel, BOFiP, CNIL, Autorité de la concurrence, AMF, ACPR and ARCEP.
  • European Union and European courts: EUR-Lex, the Court of Justice of the European Union and HUDOC.
  • Other European national jurisdictions: Normattiva, gesetze-im-internet, the BOE, Fedlex, Rechtspraak and Legilux.
  • Gulf region: ADGM, DIFC and the Saudi Ministry of Commerce.
  • International arbitration: ICC, LCIA, ICSID and UNCITRAL.

Pilot5 draws on over 400 verified institutional sources across 21 domains, and the list keeps growing, with Europe, India and the Middle East next. The full catalogue is public at pilot5.ai/sources.

Your client files

Pilot5 does not use client files to train AI models. Every statute and regulation is presented with its source, and results distinguish sourced findings from model inference. A Zero Data Retention mode for deliberations, using only models with no-retention endpoints, and a data processing agreement are available on request. Details at pilot5.ai/trust.

What it is not

Pilot5 Legal is a legal research and decision-support tool. It does not provide legal advice, and it does not certify court filings. In Florida, since June 15, 2026, the signer of a document filed with the courts represents that the legal authorities identified in the filing exist and are accurately cited. That representation, and the verification behind it, remain the lawyer’s. Pilot5 Legal gives you the text and the source to do it.

What the first week looked like

On October 7, Artificial Lawyer reviewed the launch and described Pilot5 Legal as “something standalone that is very distinct and highly structured”, suited to firms “not looking to bring aboard one of the larger legal AI platforms” and preferring “something lighter and more economical”. That is who we built it for. Pilot5 Legal is also listed on Product Hunt.

Try it

Pilot5 Legal is free to try, with credits at signup and no credit card required. Paid plans start at $29 per month, with no per-seat license. A completed deliberation on a demo Chapter 7 preference claim can be read round by round on the console, without signing in.

Try it free at legal.pilot5.ai.
