Private AI for solo & small law firms

Chat with your case files. Nothing leaves your desk.

Chambers is an on-device AI assistant that reads your documents and answers in plain English — with every answer cited to its source. Confidential by design, so you never paste a client’s matter into a public chatbot again.

What’s the indemnification cap in the MSA, and are there carve-outs?
The cap is 12 months of fees paid in the prior year. Carve-outs apply to breaches of confidentiality and IP infringement, which are uncapped.

The dilemma

Public chatbots are brilliant — and a confidentiality trap.

Pasting a client’s contract into a consumer AI tool can breach your duty of confidentiality under ABA Model Rule 1.6. Yet doing legal work by hand leaves money on the table — a solo billing $250/hour loses roughly $26,000 a year in non-recovered research time.

Confidentiality

Client data sent to third-party servers you don’t control.

Hallucinations

700+ court filings in 2025 cited AI-fabricated authority.

Cost

Enterprise legal AI starts at $500 per seat — built for BigLaw.

Chambers gives you the speed without the exposure.

How it works

From files to answers in three steps.

01

Add a matter

Drop your PDFs, Word files, and notes into a client matter. Chambers reads and indexes them on your machine.

02

Ask in plain English

“What’s the indemnification cap?” “Summarize every deadline.” No prompt-engineering, no legalese required.

03

Get cited answers

Read the answer with its source passages linked. Verify in one click, then get back to billable work.

Built for private practice

Everything a careful lawyer needs — and nothing that phones home.

On-device by default

Your files are indexed and searched locally. In local mode, no data ever leaves your computer — verified, not promised.

Answers with citations

Every response links to the exact source passage. Click to read it in context. Never a claim you cannot check.

Organized by matter

Group documents by client and case. Ask across a whole matter or a single filing in plain English.

Hybrid cloud, on your terms

Need heavier drafting? Opt in to a cloud model for that one task — with a clear prompt every time. Off by default.

Encrypted vault

Your local index is encrypted at rest and protected by an app lock. Zero telemetry, ever.

Full audit log

Every AI action is recorded — what was asked, what ran locally, what (if anything) touched the cloud.

Confidential by design

Your obligations, engineered in.

Chambers is built around the duty of confidentiality — not bolted on afterward. The default path keeps every client confidence on your device, and the app tells you plainly the moment anything would leave it.

  • Local-first: indexing, search, and answers run on your machine.
  • Explicit consent before any cloud call — per task, never silent.
  • Encrypted vault at rest, protected by an app lock.
  • Complete audit log for your file and your peace of mind.
  • No telemetry, no tracking, no account required to run it.

Questions

Straight answers.

Is my client data really private?

Yes. Chambers indexes and searches your files locally. In local mode nothing is transmitted anywhere — you can confirm it with a network monitor. There is no telemetry and no account required to run the app. Cloud features are off until you explicitly turn them on for a single task.

Does it work offline?

Completely. The local model and the document index both run on your own machine, so Chambers works on a plane, in a SCIF, or anywhere without a connection.

Which platforms are supported?

macOS (Apple Silicon and Intel) and Windows. Your library is stored locally on each machine.

Do I need to be technical to set it up?

No. A guided first-run wizard installs the local model for you and walks you through creating your first matter. If you can install an app, you can run Chambers.

Is Chambers giving legal advice?

No. Chambers is an assistive tool. You remain fully responsible for your work product, and every answer cites its source so you can verify before you rely on it. It does not replace professional judgment.

How does this fit ABA Rule 1.6 and Formal Opinion 512?

Chambers is built around the duty of confidentiality: local-by-default processing, explicit consent before any cloud use, and a full audit log of every AI action. It is designed to keep client confidences on your device — the opposite of pasting them into a public chatbot.

Keep your practice fast and your confidences yours.
