For law firms & legal teams

Secure your documents with AI assistance.

Aegis pairs a full-featured legal document editor with a voice-driven AI paralegal — protected by zero-knowledge, end-to-end encryption. Draft, review and safeguard privileged work without ever handing your clients’ secrets to a vendor.

The platform

Everything privileged work demands — and nothing it can’t trust.

Most tools force a trade-off: powerful editing or real privacy. Aegis refuses the compromise, purpose-built around the way regulated legal teams actually draft, review and protect documents.

A real legal document editor

Not a stripped-down note pad bolted onto storage. Track changes, clause libraries, defined-term linking, redlines and version history — the drafting depth practitioners expect, encrypted the whole way.

A voice-driven AI paralegal

Talk to your documents. Ask it to summarize a clause, surface missing signature blocks, compare against your playbook, or draft a response — answered by a voice avatar with tracked edits you approve.

Zero-knowledge encryption

Documents are encrypted on your device before they reach us. We store ciphertext, never keys. A breach of Aegis — or a subpoena to us — yields nothing readable.

Built for regulated practice

SOC 2 Type II controls, configurable data residency, and retention rules that map to your bar and client obligations. Compliance is the default, not an add-on.

Immutable audit trail

Every open, edit, share and AI action is written to a tamper-evident log. When a client or regulator asks who touched what and when, you have the answer in seconds.

Matter-aware workspace

Documents live inside matters, not scattered folders. The AI understands the matter context, and access follows the engagement — provisioned and revoked cleanly.

How it works

From open to airtight in three steps

01

Open a matter, encrypted

Create or import documents into a matter. They’re encrypted on your device — Aegis only ever sees ciphertext.

02

Ask your AI paralegal

Press the mic and speak. Summarize clauses, flag risk, compare to your playbook, or draft language — with tracked edits.

03

Approve, share, prove

You approve every change. Share on your terms, and let the immutable audit trail prove exactly who did what.

Security architecture

We built Aegis so we can’t betray your clients.

Privilege isn’t a feature you toggle on. It’s the foundation. Aegis encrypts every document with keys your firm controls, so confidentiality survives a breach, a subpoena to us, or a rogue insider on our side.

Client-held keys
Encryption keys are derived and held on your side. We never possess the means to decrypt your files.
Session-scoped AI
The paralegal reasons over decrypted content only inside your authorized session, then forgets it. Nothing is retained or used for training.
Tamper-evident logs
Every access and edit is appended to an immutable audit trail you can export for clients and regulators.
Your keys. Your privilege.

A vendor request for your data returns encrypted noise.

Where the others leave gaps

Storage privacy or a real editor. Aegis is the only one that’s both — for legal.

Proton protects your drive but stops at the document. Microsoft and Adobe give you powerful editors with weak client-side privacy and no legal compliance layer. Aegis closes the gap.

Verticalized on legal

We didn’t build for “professionals.” We built for lawyers.

Generic productivity suites optimize for the average user. Aegis optimizes for the one who can be disbarred for a leak. Every default — encryption, retention, audit, AI scoping — is tuned to the confidentiality duties of legal practice, from solo firms to in-house teams in finance and healthcare-adjacent matters.

Litigation & M&A

Redline contracts and draft responses by voice, with privilege intact.

In-house & compliance

Prove chain-of-custody with immutable audit trails your officers trust.

Solo & small firms

Enterprise-grade confidentiality at a single, honest per-seat price.

From the preview program

Trusted by teams who can’t afford a leak

Illustrative quotes from our early-access preview. Names withheld to protect confidentiality.

We evaluated the obvious suites and none of them could promise our clients that the vendor literally cannot read a file. Aegis can, and the drafting tools are genuinely good.

Questions

Frequently asked

Those tools were built for the general market. Aegis is built only for legal work: matter-aware documents, an AI paralegal trained to reason about clauses and privilege, and a zero-knowledge encryption model where even we cannot read your files. Proton protects storage but has a thin editor and no legal AI; Word Online and Acrobat are powerful editors with weak client-side privacy and no compliance workflow for regulated firms.

Your documents are encrypted on your device before they ever reach our servers. We hold ciphertext, not content — keys stay with your firm. That means a subpoena to Aegis produces nothing readable, and a breach of our infrastructure exposes no client data. The AI paralegal runs on decrypted content only inside your authorized session, never on our stored copies.

No. Your content is never used to train shared models. Every AI interaction is scoped to your session and discarded afterward. You get the assistance without surrendering privilege or client confidentiality.

Open a matter, press the mic, and ask in plain language: “Summarize the indemnification clause,” “flag any missing signature blocks,” or “draft a response to section 4.” The avatar reads the document context, answers by voice and text, and can make tracked edits you review before accepting — nothing changes without your approval.

Aegis is built for regulated legal practice: SOC 2 Type II controls, configurable data residency, immutable audit logs of every access and edit, and retention policies that map to your bar and client obligations. Sample compliance artifacts shown on this page are illustrative for the preview.

Both. The $24/month plan works for a solo practitioner protecting privileged work, and scales to firm-wide team seats with shared matters, roles, and centralized audit. You buy one seat or a hundred — same secure core.
