Use AI on client work without giving it your clients' names.
Hushbridge swaps client names, matter names and case numbers for placeholders on your device. You check the result, then send it.
The task
Most lawyers who use AI start with the same job: the client update. You paste in notes from a call, add the case number, and ask the AI for a clear, polite letter. Those notes carry your client's name, the matter name and their contact details.
Hushbridge works on those notes before the AI sees them. On your device it finds the names and numbers and swaps each one for a placeholder such as [PERSON_1]. You read exactly what the AI will get, then send it. When the draft comes back, the real names go back in on your device.
What Alaska's bar says
“If client confidences and secrets are not protected by the GAI tool, then the lawyer must anonymize their inputs to protect client details.”
Alaska Bar Association Ethics Opinion 2025-1, adopted by the Board of Governors on 23 April 2025.
The opinion also lets a lawyer go ahead with the client's informed consent. Hushbridge helps with the swap step the opinion describes. Whether a tool fits your duties under your own rules is still your call.
Always-protect lists for clients and matters
Client and matter names are easy to miss. A matter called Harrow Lane looks like an ordinary street name, so nothing marks it as private. Add your client and matter names to your always-protect list once. Hushbridge then swaps them in every prompt, with or without a title or role nearby. In the example below, Harrow Lane is on that list.
Before and after
Fictional example
What you paste
Draft a short update to our client Rosalind Achterberg about the Harrow Lane matter, Case No. 2:25-cv-01482. Opposing counsel, Mr. Dmitri Vasquez, offered to settle before mediation. Her email is rosalind.a@example.com and her mobile is (206) 555-0142.
What the AI gets
Draft a short update to our client [PERSON_1] about the [CUSTOM_1] matter, Case No. [CASE_NUMBER_1]. Opposing counsel, Mr. [PERSON_2], offered to settle before mediation. Her email is [EMAIL_1] and her mobile is [PHONE_1].
6 details swapped: 2 names, 1 always-protect term, 1 case number, 1 email, 1 phone number. When the reply comes back, the real values are restored on your device. Run with the legal profile and one always-protect term. All names, numbers and addresses are made up.
What you review before sending
The swap covers what Hushbridge can find. Read the protected text for these before you send it.
- Matter and project names that are not on your always-protect list yet.
- Facts that point to one client, such as a rare injury, a small town or a dispute that was in the news.
- Hearing, filing and deadline dates. The legal profile leaves most dates as written.
- Settlement figures and other amounts. Money values are not swapped.
- Judges, courts and opposing firms named without a title, role or company ending.
- Anything you copied out of an attachment before pasting it in.
Limits
- Detection uses rules, checksums and name lists. It can miss a name that has no title, role or label next to it. The facts of a matter can still point to your client after every name is swapped.
- The extension does not scan attachments. A PDF or Word file you upload to a chat site goes as it is.
- A chat site's page can read text while you type, before you send. For sensitive matters, prepare the text in the free check and paste only the protected version.
- Addresses are found in US style only. Names in non-Latin scripts and many accented spellings are not covered.
- Review before sending stays necessary. Hushbridge does not decide what your duty of confidentiality allows.
Paste a paragraph from your own notes into the free check. It runs in your browser and sends no text to an AI model.
