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.

The dilemma
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.
Client data sent to third-party servers you don’t control.
700+ court filings in 2025 cited AI-fabricated authority.
Enterprise legal AI starts at $500 per seat — built for BigLaw.
Chambers gives you the speed without the exposure.
How it works
Drop your PDFs, Word files, and notes into a client matter. Chambers reads and indexes them on your machine.
“What’s the indemnification cap?” “Summarize every deadline.” No prompt-engineering, no legalese required.
Read the answer with its source passages linked. Verify in one click, then get back to billable work.
Built for private practice
Your files are indexed and searched locally. In local mode, no data ever leaves your computer — verified, not promised.
Every response links to the exact source passage. Click to read it in context. Never a claim you cannot check.
Group documents by client and case. Ask across a whole matter or a single filing in plain English.
Need heavier drafting? Opt in to a cloud model for that one task — with a clear prompt every time. Off by default.
Your local index is encrypted at rest and protected by an app lock. Zero telemetry, ever.
Every AI action is recorded — what was asked, what ran locally, what (if anything) touched the cloud.
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.
Chambers is an assistive tool, not legal advice. You remain responsible for verifying every output.

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