EVE AI Core
The Infrastructure of No.
A hallucinated citation, a privileged document pasted into a public model, or advice the firm never authorised are all one AI output away — and human review happens after the fact, on a filing deadline. EVE Core evaluates the proposed action before it executes, returns ALLOW, BLOCK, or MODIFY against your firm’s policy, and emits a signed record of the decision.

You control which decision fields are sent; in VPC and on-prem deployments, governed content and evidence stay inside your boundary. As courts sanction AI-fabricated filings and bar associations issue AI guidance, the record has to exist at the moment of the decision. Trust Center · Security
In legal work, governing AI is inseparable from being able to show a court, a client, or a bar regulator what the AI was allowed to do. Drafting, research, summarisation, and review now run at a speed no associate review cycle matches. The duty of competence and candour does not move with it: a fabricated authority in a filing is not a typo, it is a sanctionable event, and the lawyer who signed the filing owns it.
EVE Core is the enforcement-and-evidence layer for that gap. Each proposed AI action passes a deterministic gate that applies your firm’s policy before the output can be relied on, and each produces a signed, replayable record: what was proposed, which policy version governed it, the verdict, and when. It is infrastructure the firm runs around its AI — not a legal AI assistant of its own, and not legal advice.
Legal AI drafts, researches, and summarises faster than any review process can keep up. By the time a partner catches the error, it is already in a filing — or a client’s inbox.
A research tool returns confident citations and quotes by the hundred. Human review happens after the fact, on a filing deadline — which is exactly when it is least likely to be thorough.
A case is cited with a plausible reporter number. The model is confident. Nothing in the document flags it — until opposing counsel, or the judge, does.
A fabricated authority in a brief. A privileged document pasted into a public model. A Rule 11 exposure, a bar complaint, and no contemporaneous record of who approved what.
A plain-language map of common professional obligations to concrete EVE mechanisms. This is a control mapping, not legal advice, and it does not substitute for your jurisdiction’s rules or your firm’s own AI-use policy.
| Obligation | In short | How EVE Core supports it |
|---|---|---|
| FRCP Rule 11(b) | Claims and contentions in a signed filing must be warranted by existing law | Unverified authorities are blocked at the gate before the draft is relied on, and each block is recorded with the policy version that produced it |
| ABA Model Rule 1.1 (competence) | Competence includes understanding the technology you use | Every governed AI action produces an explicit, reviewable verdict and rule trigger rather than an opaque model output |
| ABA Model Rule 1.6 (confidentiality) | Client information must not be disclosed without authority | Policy gates block privileged and client-identifying content from leaving the boundary you define; VPC and on-prem keep governed content in your tenant |
| ABA Model Rule 5.3 (non-lawyer assistance) | Reasonable efforts to ensure non-lawyer assistance conforms to professional obligations | The firm’s policy is enforced on the tool itself, on every action, with a record of what it was and was not permitted to do |
| ABA Model Rule 5.5 (unauthorized practice) | Advice must come from authorized practitioners | Actions your policy classes as client-facing legal advice are blocked or routed for lawyer review rather than returned directly |
| Privilege & work product | Protected material must stay protected | Pre-execution enforcement, not post-hoc monitoring: content that would leave the boundary never does, and the attempt is on the record |
| Audit & discovery readiness | Reconstruct what a system did, later | Signed, hash-chained decision records verifiable offline, with no live connection to EVE required |
Because the policy-pack version is embedded in each decision’s evidence, you can answer “what was the AI permitted to do on the day this brief was drafted?” with the rules that actually governed it — not a description of your current policy.
EVE CoreGuard is a pre-execution gate on the action itself. A proposed citation, summary, or client communication is evaluated against the applicable policy pack, and the gate returns a deterministic ALLOW, BLOCK, or MODIFY before the output is released. If the gate is unavailable, the path is fail-closed by default — nothing ships ungoverned.
Evaluation is designed to complete in under a millisecond, so it sits in the path of the work rather than in a review queue behind it. It is not a spell-checker and not a post-hoc reviewer: the decision is governed before it exists.
Determinism is what makes it defensible. The same inputs produce the same verdict, and any decision can be replayed to show it. That is the difference between “our tool usually behaves” and “this draft was governed, and here is the proof.”
Blocks unverified citations, privileged content, and unauthorized advice before the model returns them. Fail-closed by default.
Every outcome is ALLOW, BLOCK, or MODIFY. Same input, same output, every time — reproducible for the court, the client, and the bar.
Every decision emits a signed, verifiable record issued in the same transaction. Verifiable without EVE infrastructure. EVE Proof →
Every governed decision emits an ECDSA P-384-signed certificate — the proposed action, the verdict, the rule that fired, and the policy version — hash-chained into a tamper-evident trail. That is a contemporaneous record, produced at the moment of the decision, not a reconstruction assembled after a problem surfaces.
When a court, a client, or an insurer asks what the firm’s AI was permitted to do, the answer is a record they can verify themselves, offline, without trusting a dashboard — or trusting us. Data can stay in your tenant: SaaS, VPC, or on-prem.
Gate drafted authorities and quotations before they reach a filing, and keep a contemporaneous record of what was blocked and why.
Govern drafting and summarisation against the firm’s policy, with client-confidential material held inside the boundary you define.
Apply one enforceable AI-use policy across business units, and produce the evidence your compliance function already asks for. For compliance →
Keep privileged and work-product material from leaving the review environment, with each attempt recorded rather than silently permitted.
EVE Core enforces and proves individual AI actions. It does not give legal advice, does not make legal judgments, and does not replace lawyers, your firm’s AI-use policy, or your professional-responsibility counsel. Those define what must be true; EVE enforces it on each action and produces the evidence. Your lawyers make the decision — EVE governs and documents how the AI was used to reach it. See AI compliance software for the evidence layer in depth.
Bring a real drafting, research, or review action and we will run it through the gate: the verdict, the rule that fired, and the signed record you can verify offline. Controlled pilot from $37,500.
Start lighter: the API reference, the whitepaper, or verify a sample signed decision.
