§ 01 — The problem

Solo and small-firm litigators are doing work they shouldn't be doing.

Big firms have eDiscovery teams and six-figure Relativity contracts. You have a inbox full of client text messages, scanned PDFs, and bank statements — and one paralegal, if you're lucky.

Problem 01

Client materials arrive as a mess

Photos of receipts. Forwarded text threads. Mislabeled PDFs. WhatsApp screenshots. Every case begins with hours of human labor just classifying and filing what the client sent in. The bill runs $5K–15K before you've drafted a single sentence of the complaint.

Problem 02

Clients call three times a week

"Any update?" "When will you file?" "Did you get my email?" An estimated 30–40% of your day goes to client status updates. You can't ignore them — they'll go elsewhere. You can't bill for them either.

Problem 03

Enterprise tools weren't built for you

Relativity, Everlaw, and Reveal start at $50K a year. They solve a problem you don't have — document review at scale — and skip the one you do: turning a pile of client materials into an element-by-element evidence map.

Problem 04

ChatGPT is now a two-sided compliance problem — your client's privilege, and your bar card

The risk runs both ways. In U.S. v. Heppner (S.D.N.Y., Feb. 2026), Judge Rakoff held that documents a defendant prepared with consumer-grade Claude — then shared with counsel — were not privileged. That's your client using ChatGPT. Now flip it: the California Bar's May 14, 2026 Practical Guidance expressly extends Rule 1.6 confidentiality to AI inputs. Typing client data into ChatGPT or consumer Claude — even when no human ever sees the prompt — can itself count as a "reveal" of confidential information if there is a material risk the system accesses, retains, or trains on it. That's you using ChatGPT. Two different rules. Same consumer tool. Same disciplinary exposure.

§ 02 — What LEXVECTOR is

A dedicated AI paralegal for each case. It works while you sleep. You review and decide.

What LEXVECTOR is not

  • Not an eDiscovery review platform
  • Not an AI that drafts your pleadings
  • Not a chatbot you have to prompt
  • Not a SaaS dashboard you have to log into
  • Not an ALSP with overseas staff doing the work

What LEXVECTOR is

  • A long-horizon agent that lives in each case file
  • A privileged AI workspace built to survive Heppner
  • An attorney-directed channel, structurally distinct from consumer AI
  • An email-native product — your inbox is the interface
  • A way for small firms to operate like big ones
§ 03 — The privileged layer

Three structures that make LEXVECTOR fit California's new rules.

In four months, the question for every California litigator changed twice. U.S. v. Heppner (S.D.N.Y. Feb. 2026) made client AI conversations a privilege problem. The California Bar's updated Practical Guidance (May 14, 2026) made agentic AI a supervision problem. PAWS — Privileged AI Workspace Structure — was built as the answer to both.

I

Attorney-Directed

Client AI use happens at the direction of counsel, under terms in the engagement letter — not as independent consumer-grade AI use. The contractual basis matches the doctrinal path Judge Rakoff acknowledged in Heppner: direction, not coincidence, distinguishes privileged from unprivileged.

II

Meaningful Supervision

LEXVECTOR operates as an extension of the firm — full attorney access, every agent action confidence-scored and routed to attorney review when ambiguous. Every client communication confirms back through the attorney before sending. This is the "meaningful lawyer supervision and review" the May 14 Practical Guidance demands, applied as the substrate of the product.

III

Zero-Retention Infrastructure

Client materials and AI conversations never train shared models. Case data is encrypted at rest, isolated per matter, and never used for any purpose other than that representation. Built to the Rule 1.6 confidentiality standard the updated Guidance now reads onto AI inputs.

Event I · February 2026

U.S. v. Heppner

(S.D.N.Y., Judge Jed S. Rakoff) — 31 documents a defendant prepared with consumer-grade Claude, then shared with his defense team, held not privileged — the AI was not at counsel's direction, and the platform was consumer-grade. Your clients are doing the same thing on ChatGPT right now. You cannot stop them. You can give them a privileged channel to use instead.

Event II · May 14, 2026

California Bar · Practical Guidance

(Board of Trustees, approved May 14, 2026) — Agentic AI cannot make substantive legal determinations, communicate legal advice, or file pleadings without meaningful lawyer supervision and review. Rule 1.6 confidentiality now expressly covers AI inputs — including when the lawyer (not just the client) types client data into ChatGPT. Rule 3.3 requires verification of all AI-cited authorities before submission to any tribunal. The Guidance is effective now. The disciplinary risk runs to your bar card.

§ Court-ready evidence chain

Every AI interaction is logged into an immutable, privilege-tagged audit log. When opposing counsel files a motion to compel or challenges privilege — or when the Bar asks how supervision was performed — the firm can produce a court-ready privilege log + supervision record meeting FRCP 26(b)(5) and the May 14 Practical Guidance standards. Included in every case, no per-event fee.

§ 04 — What it delivers

Six things LEXVECTOR does for every case.

You're not paying for a platform. You're paying for deliverables — the same work product a paralegal would hand you, ready for your review.

I

Evidence Map for Pleadings

LEXVECTOR ingests everything the client uploads and organizes it against each cause of action — element by element. You get a matrix showing what evidence supports each claim, plus a missing-evidence checklist to send back to the client.

Deliverable · Element-by-Element Evidence Map
II

Discovery Builder

Based on the pleadings, the agent drafts your RFP, interrogatory, and RFA topic lists, suggests subpoena targets, and writes a discovery strategy memo identifying your strongest evidence and most urgent gaps.

Deliverable · Draft Requests + Strategy Memo
III

Discovery Response

Forward opposing counsel's 30-page RFP to the case email. LEXVECTOR parses each request, searches your case file for responsive documents, drafts a request-by-request response matrix, and surfaces privilege concerns for your review.

Deliverable · Response Matrix + Objection Drafts
IV

Client Inquiry Auto-Reply

When a client emails to ask for an update, LEXVECTOR drafts the reply and sends it to your inbox. You click [Send] and it goes out from your email address within 30 seconds. Every client-facing message requires your confirmation — no exceptions.

Deliverable · Attorney-Confirmed Status Reply
V

Motion & Trial Evidence Preparation

As your case moves toward MSJ and trial, LEXVECTOR builds an exhibit-by-exhibit evidence dossier: chain of custody for each document, foundation analysis for admissibility, hearsay and authentication issues flagged with proposed cures, and a witness-by-witness matrix tying each piece of evidence to the testimony needed to authenticate it. Every exhibit comes with a one-page foundation memo ready for your review.

Deliverable · Exhibit Dossier + Authentication Roadmap
VI

Daily Morning Brief

At 8 AM, one email lands in your inbox. It tells you which cases need a decision today, which clients uploaded materials overnight, what deadlines are coming this week, and how many hours the agents saved you. Ten minutes to plan the day.

§ 05 — Inside a real case

A glimpse from Smith v. Jones — a $200K breach-of-contract matter.

Four moments from the same case file. Same client. Same agent. Different stages of the litigation lifecycle. This is what the work product actually looks like.

I Intake · Day 1

Your client uploads — the agent verifies on the spot

Robert (the client) gets a Magic Link by email. Twelve-step intake on his phone. When he uploads a document labeled "bank statement," the agent recognizes it's actually the disputed invoice — and asks him to confirm before filing it under the wrong category.

CHEN LAW FIRM Step 6 of 12

✓ Yes, that's it ✎ No Skip
II Day 3 · Confidence threshold hit

The agent flags ambiguity — and waits for you

A WhatsApp screenshot comes in. The agent's classification confidence is 0.71 — below the threshold. Instead of guessing, it sends a 30-second clarify email. You reply "B" by voice from your car. The task resumes automatically.

The Evidence Map — every fact linked back to its source

Once enough materials are in, the agent generates an element-by-element Evidence Map. Six rows. Each fact carries a confidence score and a source link. Click "Invoice_0324.pdf, p.2" — the PDF opens to page 2, highlighted on the "Net 30" clause that establishes breach.

IV Day 142 · Discovery served

Opposing counsel sends discovery — the agent drafts the response

Forward the opposing counsel's discovery request to the case email with subject [OUR-DISCOVERY]. Twenty-four minutes later, a Plan email lands in your inbox: draft RFPs, ROGs, and RFAs — bounded by California's statutory limits — with a strategy memo and source-linked findings. Approve, edit, or clarify in one tap.

Same agent, same case file, same inbox — from intake to discovery in four months. No dashboard switching, no manual data re-entry, no consumer AI exposure. Just the work product, attorney-reviewable, source-linked, ready when you are.

§ 06 — Inside the inbox

Your inbox is the product.

We made one counterintuitive but deliberate decision: LEXVECTOR has no main dashboard. Every interaction happens where you already work — Outlook, Gmail, your phone's mail app.

Each morning at 8 AM, you receive a single email. It's a status report from the team of agents working your cases:

  • Decisions you need to make today
  • Documents clients uploaded overnight
  • Auto-drafted replies waiting for your approval
  • Deadlines and hours saved this week
§ 07 — How it works

Six design choices that make LEXVECTOR safe to use.

A litigator's tolerance for AI error is zero — one bad citation and you're explaining yourself to the bar. Everything below was built with that in mind.

Principle 01

Every fact has a source link

Each fact, claim, and coverage item in LEXVECTOR's output is linked back to the source document, page, and paragraph. One click to verify. The agent is structurally incapable of generating a fact without a citation.

Principle 02

It tells you what it isn't sure about

Every output carries a confidence score. High-confidence work is delivered. Low-confidence work is flagged for your review. Privilege and sensitive content never auto-process — they always require a human decision.

Principle 03

Email is the workflow

Forward a discovery request to the case email and the response pipeline kicks off. Reply to the agent and it understands. No plugin to install, no IT approval needed, no new tool for your paralegal to learn.

Principle 04

Per-matter isolation — everything confidential

Each client's case file lives in its own encrypted workspace, isolated from every other matter on the platform. No cross-firm data leakage. No background training on your case materials. Every document, communication, and AI interaction is treated as confidential by default — only you and your firm have access.

Principle 05

The lawyer always decides

Every output is an attorney-reviewable draft. The agent doesn't write your pleadings, predict outcomes, estimate settlement value, or file anything with the court. Nothing leaves your firm without your name on it.

Principle 06

Priced like a litigation vendor, not a software seat

This isn't a software subscription. LEXVECTOR is priced like court reporters and e-discovery vendors — case-level disbursements that pass through to your client under standard California fee agreement provisions. Your firm pays a $500 one-time activation fee. Everything else moves through the case.

§ 08 — Hard boundaries

We are clear about what we won't do.

UPL risk is real. Bar discipline is real. LEXVECTOR is designed so neither falls on you. Here is exactly where the line sits.

LEXVECTOR will not

  • Give clients legal advice
  • Replace attorney judgment or strategy
  • File anything with a court
  • Predict case outcomes or win probability
  • Estimate settlement value
  • Generate facts without source citations
  • Send any client-facing email without your confirmation
  • Certify a translation as legally binding

LEXVECTOR will always

  • Cite each fact to source (document, page, region)
  • Label every output as attorney-reviewable draft
  • Flag low-confidence content for review
  • Route certified translations to human review
  • Maintain a full data access audit log
  • Encrypt all data at rest with AES-256
  • Enforce role-based access control
  • Name the attorney as the final responsible party (in the MSA)
§ 09 — Pricing

Priced as a case disbursement — and as privilege insurance.

LEXVECTOR is priced like the litigation support services already on your invoice — court reporters, e-discovery vendors, expert witnesses — not like a per-seat SaaS tool. Pass through to the client at a 30% discount (default), or pay it from the firm at full price (used for contingency, pro bono, or relationship matters). PAWS architecture, privilege log export, and the full client experience module are included in base pricing — no add-ons, no per-event fees.

Tier I · One-time

Pass-Through · 30% off
  • Pleading Support$500$714
  • Discovery Support$2,500$3,570
  • Mediation Support$1,900$2,714
  • MSJ Support$3,200$4,570
  • Trial Preparation$3,800$5,430
§ The legal basis

Pass-through is already standard practice in California.

Standard "costs and expenses" provisions in California fee agreements already authorize pass-through of matter-specific technology costs to clients — the same mechanism that lets you bill clients for court reporters, e-discovery vendors, and expert witnesses. The 30% volume discount is a vendor-level discount tied to billing path, not a kickback or markup — structurally identical to per-matter pricing Westlaw, Lexis, and Relativity have offered for decades without raising CRPC concerns.

  • Recommended engagement-letter language provided, with explicit volume-discount disclosure
  • Itemized as case costs or disbursements on each invoice — the same line as court reporters
  • No markup permitted without separate informed written client consent (no-markup rule preserves structural integrity for all firms)
  • Single disbursements over $5,000 require prior written client authorization
  • Attorney supervision and independent professional judgment remain with you

What it looks like on a typical commercial matter

12-month lifecycle · Tier II firm
Component Pass-Through Firm-Pays
Monthly Technology Fee · 12 mo $1,908 $2,724
Discovery Support Package $2,500 $3,570
MSJ Support Package (50% probability) $1,600 $2,285
Typical case total $4,000 – $4,900 $5,700 – $7,000
On a $200,000 commercial matter, the pass-through path puts LEXVECTOR at 2–2.5% of the client's bill — less than a typical deposition transcript ($1,500–$3,500), and far less than what e-discovery vendors charge ($5,000–$50,000) on the same case. The firm-pays path runs higher because LEXVECTOR absorbs the administrative cost of client-level invoicing on the discount path; the 30% savings returns to the actual payer.
§ Which path, when

Default pass-through. Switch when the case calls for it.

Every new matter defaults to pass-through. Firms can opt into firm-pays on a matter-by-matter basis. No firm-wide commitment required — each case is decided independently.

  • Pass-through — fee-paying clients on standard commercial matters (≈ 80% of cases)
  • Firm-pays — contingency cases (no fee until resolution)
  • Firm-pays — pro bono or non-profit clients
  • Firm-pays — relationship clients on existing discounted arrangements
  • Firm-pays — small matters under $20K where LEXVECTOR would exceed 15% of total bill
§ A second way to think about it

Of that $4,000/year, about $700 is privilege insurance.

In the post-Heppner world, your client's AI use is either privileged or it isn't. PAWS architecture, the audit log, and court-ready privilege log export inside LEXVECTOR represent roughly $700 of each year's case cost — and they exist so a single privilege challenge doesn't undo the rest of the work on the file.

On a $200K commercial matter, a privilege waiver can cost the client the core narrative of the case. $700 of disbursement is a rational price for that protection — far less than the deposition transcript on the same matter, and orders of magnitude less than the cost of arguing privilege from a weaker position.

Common questions

How does LEXVECTOR address U.S. v. Heppner?

Heppner (S.D.N.Y. Feb. 2026) held that documents a defendant prepared with consumer-grade Claude — and later shared with counsel — were not protected by attorney-client privilege or work product doctrine. The court's reasoning turned on the absence of attorney direction and the consumer-grade nature of the tool. LEXVECTOR is structurally the opposite: client AI use happens at the explicit direction of counsel under engagement-letter terms, inside a privileged enterprise workspace with full attorney supervision, with an immutable audit log evidencing every interaction. We call this architecture PAWS — Privileged AI Workspace Structure.

What this means for California. Heppner is a federal decision from the Southern District of New York, but its reasoning applies to any client communication with consumer AI — including communications by California clients with their California attorneys. California is independently moving in the same direction: on May 14, 2026, the California Bar Board of Trustees approved updated Practical Guidance that, for the first time, specifically addresses agentic AI and requires meaningful lawyer supervision over any AI system that makes substantive legal determinations. California litigators should expect that Heppner's privilege analysis will be cited by adversaries in California state and federal proceedings, and that the May 14 Guidance — which is effective now — defines the supervision standard LEXVECTOR was built to.

If I (the lawyer) use ChatGPT to analyze a client's documents, am I violating Rule 1.6?

Probably yes — and the California Bar just said so directly. The May 14, 2026 Practical Guidance, together with proposed Comment 2 to Rule 1.6, expands the definition of "reveal" to include exposing confidential information to AI tools where there is a material risk the system may access, retain, or use the data inconsistently with the duty of confidentiality. This catches consumer-grade ChatGPT, consumer Claude, and similar public platforms — whose terms of service expressly permit retention, training on user inputs, and disclosure to third parties.

The practical implication is that the disciplinary risk runs to you, not just your client. When your client uses ChatGPT, the consequence is privilege waiver — bad for the case. When you use ChatGPT to analyze your client's documents, the consequence is a Rule 1.6 violation — bad for your bar card. Most small-firm attorneys still treat ChatGPT as a productivity tool. After May 14, the State Bar treats it as a third-party disclosure.

How LEXVECTOR solves this. Every matter lives in its own encrypted workspace, isolated from every other case on the platform. We do not train shared models on client data. We do not share inputs with third parties. The contractual terms between LEXVECTOR and your firm are written to satisfy the "material risk" test in the new Comment 2 — so that when you analyze a client document inside LEXVECTOR, you are not making a Rule 1.6 disclosure. You are exercising your duty of confidentiality, not breaching it.

How does LEXVECTOR align with California's May 14, 2026 agentic AI guidance?

The California Bar's updated Practical Guidance (approved by the Board of Trustees on May 14, 2026) sets out three requirements that map directly to LEXVECTOR's design philosophy from V0:

1. Meaningful lawyer supervision over agentic systems. Every agent action in LEXVECTOR carries a confidence score. High-confidence work proceeds; anything ambiguous is routed to an attorney decision. Every client-facing message requires attorney confirmation before sending. The full audit log produces a record of supervision that can be inspected if the Bar ever asks.

2. Confidentiality covers AI inputs under Rule 1.6. Per-matter isolation, zero-retention infrastructure, encryption at rest, and a contractual prohibition on cross-matter or shared-model training. Client materials never leave the privileged container of the case.

3. Verification of all AI-cited authorities under Rule 3.3. Every fact LEXVECTOR generates is structurally linked to a source document, page, and paragraph. The system is incapable of producing a citation that does not trace back to a verified source — eliminating the hallucination class of risk that has produced the Bar's sanctions trend since 2023.

We did not retrofit these features in response to the May 14 update. They were the design philosophy from V0. The Bar's guidance and LEXVECTOR's architecture were converging on the same answer to the same question.

What's in the engagement letter?

We provide recommended language covering three things: (1) pass-through of case-specific technology costs as a disbursement, with explicit volume-discount disclosure; (2) attorney's direction of client AI use as part of the representation; and (3) an exclusive-channel commitment asking the client not to discuss the matter on consumer AI platforms like ChatGPT. The Exclusive Channel provision is new in V5 and exists to give attorneys an ethical defense if a client violates it.

Is my client data secure?

All data is encrypted at rest with AES-256 and in transit with TLS 1.3. We maintain a full audit log of every access event. We're built BAA-ready and on a path to SOC 2 Type I within twelve months of launch. Your data is never used to train shared models. Each matter is isolated; cross-matter access requires explicit firm-level authorization.

How does LEXVECTOR protect against UPL exposure?

Every client-facing message requires explicit attorney confirmation — no auto-send is possible. Intent classification screens for legal-advice language and routes it to your review. The client-facing email templates are restricted to status reporting; they don't make legal judgments. Your master services agreement names you as the final responsible party.

What happens if the AI gets something wrong?

Every output is an attorney-reviewable draft with source links on every fact. If a fact is wrong, you'll see it before it leaves your firm. The agent flags low-confidence items rather than guessing. We maintain an evaluation framework with 50+ ground-truth cases and run regressions on every model update.

Do I need to install anything?

No. LEXVECTOR works through your existing email — Outlook, Gmail, or any IMAP-compatible client. There is no plugin requirement, no IT approval needed. An optional Outlook add-in is available for one-click case routing, but the core workflow runs entirely on email forwarding.

What does it cost, and who pays?

Your firm pays a one-time $500 activation fee. Everything else — the monthly per-case technology fee ($89–$189) and stage-specific support packages ($500–$3,800) — is passed through to the client as a case disbursement, the same way you bill for court reporters and e-discovery vendors. A typical commercial matter runs $4,000–$4,900 in total LEXVECTOR fees across its 12-month lifecycle, or about 2–2.5% of a $200,000 client matter. Of that, roughly $700/year is privilege-architecture (PAWS) protection — included in base, not an add-on. See the full pricing breakdown for details.

What practice areas do you support?

V0 supports California commercial litigation — breach of contract and small business disputes. Additional practice areas will be added based on design-partner demand and engineering capacity.

What's the Design Partner program?

We're onboarding a select group of California firms as design partners. Twelve months free, hands-on support, direct input into the product roadmap, and 50% off list price for the lifetime of the engagement. In exchange, we ask for honest feedback.
