Rendex — Private AI for Law Firms

The Problem

Your firm's knowledge is trapped in folders.

Every hour your attorneys spend searching is an hour they're not billing.

!

The Partner

Spends 25 minutes before every client call hunting through folders, emails, and iManage for the right version of a contract.

!

The Associate

Spends half a day looking for a motion your firm already wrote two years ago. It exists. Nobody can find it.

!

The Deal Team

Takes two weeks to review documents in a data room that should take two days. The documents are there. The bottleneck is search.

Rendex turns that search into one question and a cited answer.

How It Works

Three steps. Zero cloud.

From document upload to cited answer — everything runs on your hardware, behind your firewall. No data ever leaves your network.

1

Upload Your Documents

Drag in contracts, briefs, filings — PDF, DOCX, TXT. Rendex indexes everything locally. Scanned PDFs get OCR'd on-device. Your IT runs our installer in under an hour.

2

Ask in Plain English

"Find all non-compete clauses over 50 miles." "When does the Brightline lease auto-renew?" Ask questions like you'd ask a senior associate.

3

Get Cited Answers

Every answer links to the exact source document, section, and page. Click any citation to see the original text. Verify in seconds, not hours.

What You Can Ask

One interface. Ask for what you need.

Comparisons, chronologies, clause tables, depo prep, precedent search — ask in plain English and get cited answers. No separate tools to learn.

Comparisons

“What changed between the March and June drafts of the MSA?” — cited to both versions

Clause Extraction

“List every indemnification clause across these 40 contracts” — cited to document and page

Chronologies

“Build a timeline from the Smith matter file” — every event cited to its source

Depo Prep

“Draft a witness outline for Dr. Lee using the deposition transcripts” — cited to exhibits

Precedent Search

“Do we have prior work product on restrictive covenants in Texas?” — filtered by matter

Our Approach

Your data is never used to train the AI.

Some AI tools absorb your documents into the model itself. Rendex doesn't. It searches your files at the moment you ask a question, then throws away the context. Nothing is memorized.

Harvey and Copilot send prompts to the cloud. Rendex doesn't.

Other AI Tools

Documents absorbed into modelYour data becomes part of the AI's weights permanently

Can't fully delete dataThe model may still "remember" removed documents

Answers from memoryNo source documents to verify — trust the model or nothing

No audit trailCan't trace how an answer was generated

Rendex

Documents searched, never absorbedFiles stay in your storage — the AI reads them on demand

Delete means deleteRemove a file and it's gone — instantly, completely

Every answer cites a sourceClick any citation to see the exact document, page, and section

Full audit trailEvery query, every source, every user — logged and exportable

Architecture

What runs on your server.

Every component runs inside a single Docker deployment on your hardware. Nothing reaches the internet.

Why Rendex

Your firm wants AI. Compliance says no.
Rendex is built to be the tool they approve.

Attorney-client privilege means data cannot leave the building. Cloud AI tools are blocked by ethics obligations. Rendex was built for this reality.

100% On-Premises

Runs on a device in your office. Zero outbound network connections. You can unplug the internet cable and it still works. No data sent to any third party, ever.

Zero Vendor Access

We never see your data. We're the plumber who installs the pipes, not the water company. If Rendex disappears, your system keeps running.

Every Answer Cited

Click any citation to see the exact source text highlighted. The AI is constrained to retrieved documents — no hallucinated case law, no made-up clauses.

Complete Document Control

Delete a document and it's gone — completely, immediately, verifiably. No residual knowledge in the model. No shadow copies on someone else's server.

Role-Based Access & Ethical Walls

Five roles from Admin to Staff. Matter-level permissions. Ethical walls enforced at the query level. Every access logged to an immutable audit trail.

Live in Under a Day

Docker Compose handles everything. Your IT team runs our installer in under an hour with guided onboarding, or we ship a pre-configured workstation. No infrastructure changes.

What it replaces

Real workflows. Measurable time savings.

These are the tasks that eat hours every week. Rendex doesn't replace lawyers — it replaces the manual search, re-reading, and cross-referencing that slows them down.

Litigation Chronology

Before: 8–12 hours manually building a timeline from a 1,500-page matter file
After: 2–4 hours — Rendex generates a cited timeline, attorney reviews and refines
What changed: every event linked to source page; exported to Word

Time recovered

6–8 hours per chronology

Due Diligence Clause Review

Before: 2–3 days to build a clause matrix from a 200-document data room
After: same day — every row linked to the source page and section
What changed: fewer missed provisions; associates focus on analysis, not extraction

Time recovered

1–2 days per data room

Internal Precedent Search

Before: "Do we have precedent for X?" — hours of folder-hunting, Slack DMs, asking partners
After: minutes — ask Rendex, get cited results filtered by matter and practice group
What changed: firm knowledge is searchable, not tribal; new associates ramp faster

Time recovered

30–60 minutes per search

These are representative scenarios, not guarantees. Results depend on document quality, practice area, and adoption. The 90-day evaluation gives your team time to measure real impact before committing to an annual license.

Clear Boundaries

What Rendex is not.

Clarity builds trust. Here's exactly what we don't do. We're the only layer between your documents and your team — no third-party model, ever.

×

Not cloud AI. No data is sent to OpenAI, Google, Anthropic, or any third party. Ever.

×

Not a legal advice engine. Rendex retrieves and cites your documents. It does not practice law.

×

Not training on your data. The AI model is pre-trained and never modified by firm documents.

×

Not storing data in the model. Documents exist in a vector database and can be removed instantly.

Security Posture

What your security team needs to know.

Rendex is designed to pass security review without exceptions or workarounds. Every claim below is verifiable by your IT team.

1. Data Isolation

✓

Zero Outbound Egress

No network calls leave the server. No telemetry, no license checks, no API calls. Verify: run tcpdump or your network monitor during operation.

✓

Air-Gap Compatible

After initial Docker image pull, the system runs with zero internet. Deploy on fully air-gapped networks via USB transfer. Verify: disconnect the network cable — Rendex keeps running.

2. Encryption

✓

TLS 1.3 In Transit

All browser-to-server traffic encrypted via HTTPS with TLS 1.3. Self-signed cert generated at install, replaceable with your own CA cert. Verify: check the certificate in your browser.

✓

Internal Service Isolation

All inter-container traffic stays on an internal Docker network. PostgreSQL, Qdrant, and Ollama are not exposed to the host network. Two open ports total: 80 and 443.

3. Access Control

✓

RBAC + Ethical Walls

Five roles (Admin to Staff). Matter-level permissions enforce ethical walls at the query layer. No cross-matter leakage. Verify: log in as a restricted user and attempt a cross-matter query.

✓

SSO via Microsoft Entra ID

OpenID Connect with JWKS signature validation. Your firm's MFA, Conditional Access, and device compliance policies apply automatically. Revoke access in Azure — Rendex locks them out instantly.

4. Audit & Compliance

✓

Immutable Audit Trail

Every query, login, document access, and permission change is logged to a tamper-proof append-only table in PostgreSQL. Exportable for compliance review. Verify: query the audit table directly.

✓

Aligned with SOC 2 Type II Controls

Rendex is architected around SOC 2 control objectives: access control, audit logging, encryption, change management. Not yet independently audited — we're transparent about that.

5. Vendor Access

✓

Zero Vendor Access

Rendex has no backdoor, remote shell, or auto-update mechanism. We cannot access your system. Updates are manual, versioned Docker images you pull on your schedule.

✓

Your Data Only

Rendex only indexes documents your firm uploads. Zero training on third-party corpora. No scraped case law, no licensed content. If you didn't upload it, it doesn't exist in the system.

6. Data Lifecycle

✓

Complete Data Deletion

Remove a document and it's purged from the vector database and file system immediately. No residual embeddings. No shadow copies. Verify: delete a document, then search for its content.

✓

Minimal Attack Surface

Eight Docker containers. Two open ports (80, 443). Rate-limited API. No public-facing admin panel. PostgreSQL bound to internal Docker network only.

^* After installation (or offline image load), Rendex operates with zero outbound network access. Initial setup requires a one-time Docker image pull or offline USB transfer.

Enterprise Ready

Sign in with Microsoft. Nothing else to configure.

Your attorneys already use Microsoft 365. Rendex plugs directly into your firm's Azure AD — no extra passwords, no separate user management.

One-Click SSO via Microsoft Entra ID

Attorneys click "Sign in with Microsoft" and they're in. OpenID Connect authorization code flow with JWKS signature validation. No SAML XML. No federation headaches. Your IT registers one app in Azure and it's done.

Your MFA, Your Policies

Conditional Access, MFA, device compliance, geo-restrictions — whatever your firm enforces in Azure AD applies to Rendex automatically. We inherit your security posture instead of reinventing it.

Centralized User Control

Add and remove users from Azure AD — Rendex follows. When someone leaves the firm, their access is revoked instantly. Domain allowlisting ensures only @yourfirm.com accounts can authenticate. Optional auto-provisioning creates Rendex accounts on first login.

Break-Glass Local Admin

If Azure AD is unreachable, the local admin account always works. Every SSO login, failure, and provisioning event is logged to the immutable audit trail. Full visibility for compliance and incident response.

SSO with Microsoft Entra ID is included on all plans — no extra charge.

Quality Assurance

Tested against 100,000+ legal documents.

Every release is stress-tested with real court opinions, SEC filings, and contracts before it ships.

Common Objections

Questions we hear from managing partners and IT.

Those tools are designed for general productivity — email drafting, summarization, brainstorming. Rendex is purpose-built for privilege-sensitive document analysis: page-level citations, ethical walls enforced at the query layer, and zero data leaving your network. Most firms use both: Copilot for day-to-day productivity, Rendex for deep document review and work product search where privilege matters.

You don't need to maintain it. We deploy Rendex via a single Docker Compose command — guided deployment with your IT team or MSP, setup in under an hour. Updates are quarterly Docker image pulls (one command). There's no infrastructure to manage beyond the server itself. Priority support is included on all annual licenses.

Every answer includes a citation — document name, page number, and the exact source text highlighted. Click any citation to see the original. If Rendex can't find supporting evidence in your documents, it says so instead of guessing. The 90-day evaluation gives your team time to verify accuracy against real matter files before committing to an annual license.

Your data stays on your hardware — we never had access to it. Run docker compose down and the software is removed. Your documents remain exactly where they were. No lock-in, no export fees, no data held hostage. The 3-month minimum exists so we can properly onboard your team — after that, cancel anytime.

A server or workstation with an NVIDIA GPU (8 GB+ VRAM), 32 GB RAM, and 500 GB SSD storage. Many firms already have this as a spare workstation or underused server. We also support running on a dedicated mini PC (~$3K one-time). We'll confirm your hardware during the pilot call.

iManage integration is available now — Rendex connects via the iManage API and indexes documents in place without copying them out of your DMS. NetDocuments and SharePoint connectors are in development. You can also upload documents directly via drag-and-drop or bulk import.

Yes. Email info@rendex.law and we'll send the security packet within 48 hours. Covers architecture, data flow, encryption, access controls, audit capabilities, and our SOC 2 control alignment documentation.

Yes. After the initial Docker image pull (or a USB transfer of images), the system runs with zero internet access. No outbound connections, no license checks, no telemetry. Your IT team can verify with a firewall rule or packet capture.
