A private AI assistant for solo and small firms — the confidentiality posture the biggest firms are building for themselves, sized for a practice that doesn't have a data center. Client matter data is processed on your own hardware.
The largest firms are now buying their own hardware so sensitive client work never touches an outside vendor. A four-lawyer firm can't stand up a data center — but it carries the same duty of confidentiality.
Typing client work into a public chatbot isn't a shortcut; it's an exposure. B-Ai Box gives a small practice the private-AI posture the market leaders are building, without the spend or the staff.
A capable AI that runs entirely in your office: a working-memory "brain" paired with a document vault. Think of the vault as your library and the brain as a desk — for each question it pulls the passages it needs, answers, and puts them back. Your archive is never uploaded and never used to train anything.
The assistant runs on a machine with 128GB or more of unified memory. Already have a capable workstation? Bring it. Prefer it turnkey? We supply and configure a reference box for you.
Starter storage is two 2TB NVMe drives, set up mirrored by default so a single drive can fail without data loss. Higher-capacity and multi-drive configurations scale from there.
One engine for matter Q&A, summaries, grounded drafts, and discovery-lite work; a separate assistant for calendar and admin. The two keep separate memory — matter files never cross into the admin lane.
Ask in plain English and get a grounded answer, with the source passages it relied on.
Boil a deposition or a sprawling email thread down to what matters.
Get a junior-associate draft of a letter or memo that you review and finish.
Run over a document set to surface what looks relevant, so you decide faster.
Calendar and admin run in a separate lane that never sees matter files.
Any outbound email is drafted for your review — nothing leaves until a human approves it.
Everything about client content runs on-premises. The protections aren't a promise — they're how the system is built.
Matter-level access controls decide what the AI can open. It may read the originals you authorize and write drafts into a sandbox — it cannot freely overwrite or delete your vault.
Anything that reaches outside — sending an email, using a research tool, any cloud — is a deliberate, logged side door that a human approves. It is never the default path for client materials.
Heavy indexing runs on a night queue so it never slows your day, and the vault stays usable even if the AI is down.
Backups are actual copies, kept separately — not just a RAID mirror. Optional encrypted box-to-box replication sends them to a second location you control.
Lawyers use their existing PCs through a browser on the office network. Remote access is available only over a private VPN.
The AI model itself runs on the box. Client matter data is processed on your hardware — not sent to an outside AI service, and not used to train one.
Its output is junior-associate work product that a lawyer must review and supervise — consistent with the competence, confidentiality, and supervision duties described in ABA Formal Opinion 512 on the use of generative AI in practice.
Practices that want the confidentiality posture the biggest firms are building for themselves — without the spend, the data center, or the 100-person AI team. If your calls, your mail, and your documents are confidential, this was built for you, by a lawyer who practices.
Plain-language wording a firm can adapt into an engagement letter or website FAQ — no overclaim.
To protect your confidential information, this firm uses an artificial-intelligence system that runs on our own equipment in our office. Your matter files are processed on-premises and are not uploaded to outside AI services or used to train any outside model. Access is limited by matter, and any communication the system helps prepare is reviewed and approved by a lawyer before it is sent. We use these tools to work more efficiently while a lawyer remains responsible for the work and for safeguarding your information.
