Trained on your matters, not the internet

Nine days of contract review, done before lunch

LexCore reads a new agreement against your playbook, your closed matters and your precedent. Then it shows you the clause, and the past deal the position came from. What you get is your house position with the source attached, rather than a generic legal opinion.

Client confidentiality

Where your client's documents go, in plain words.

Rule 19 of the Rules of Professional Conduct makes a client's confidences your duty. So before you upload anything, you should know who reads it.

On the hosted cloud, the AI provider named on our sub-processor register reads the text, under contract and with no training on your data. The same register says where the documents rest. Each firm's records are kept apart from every other firm's.

A sovereign deployment runs on infrastructure you control, with no third-party AI provider in the document path. It exists for two reasons: privileged files stay strictly confidential, and an organisation under a localisation obligation can satisfy it. Host it in Nigeria if a regulator requires it, or wherever your firm already keeps its systems.

Most firms run hybrid: a dedicated sovereign deployment beside the hosted quality tier. Routine work gets frontier models and full multi-round debate on the quality tier, and the confidential files run on local models on the sovereign deployment. The tier is recorded on every review.

Uncapped indemnity extends to the Provider's own negligence

Clause 7.2 makes the Customer indemnify losses "howsoever arising", with no cap and no carve-out for the Provider's negligence. Your playbook treats this as a hard stop. Negotiate a cap at contract value.

The category difference

This is not a chat box with a legal prompt.

A chat wrapper hands you prose and leaves the checking to you. That is the expensive part, and the part a court cares about. LexCore works the other way round. The checking happens first, mechanically, and what reaches you is a marked-up document with the evidence already attached.

A chat wrapper
Returns prose. You verify every claim by hand.
LexCore
Returns a marked-up .docx. A finding that cannot be anchored to an exact span of your document is rejected before you ever see it.
A chat wrapper
One model, one opinion, stated with equal confidence either way.
LexCore
Specialist agents review blind, in up to three rounds. An arbiter settles conflicts, and anything it cannot settle goes to a lawyer. You can read the transcript.
A chat wrapper
No record of who supervised what, or how closely.
LexCore
Human Gates on the findings that need them, and a Review Level set before the work and stored with it. Supervision is on the record, so nobody has to rely on memory.
A chat wrapper
Trained on the internet. It has never seen what your firm agreed to.
LexCore
Reads against your playbook, your closed matters and your precedent, and shows you the past deal it took the position from.
A chat wrapper
Copy, paste, reformat, and hope the numbering survived.
LexCore
Native Word tracked changes written into the OpenXML package, with tables, schedules and legal numbering intact.
A chat wrapper
Generic jurisdiction. A tenancy agreement under the Lagos Tenancy Law gets read like a New York lease.
LexCore
Nigerian statutory grounding, with the regulatory position cross-referenced and cited.
Architectural sovereignty

Four layers of verification on every clause

Hallucination control is built into the pipeline. If a finding has no exact source anchor, we discard it before you ever see it.

Exact character offsets
No approximate spans. Every citation points to an exact byte range.
Corpus precedent match
Compares the current draft with deals you have already closed.
Human Gate enforcement
A high-risk deviation does not go through until a reviewer confirms it.
Immutable audit trail
Every recommendation and approval is hashed and stored in-tenant.
