Your associate pasted the client memo into ChatGPT. You still answer for the file.

If your day is client files, this is for you.

You don't have to call yourself a "professional services firm." If client work sits on your computers and your people are already using AI to move faster, you're in the right place.

The file leaves the building at the worst time. Here's where you'd lose it.

Find your firm below. The same paste, the same folder, a different client.

1. Law firm, the night before a filing. Your associate pastes a client memo into a public tool to tighten the wording. The memo is privileged. You find out when the client asks where your AI policy is, and you still have to answer for that file.
2. Accountant at month-end. A staff accountant drops a client's statements into ChatGPT to clean the labels. The numbers are now on a public tool. You still have to sign the return, and you cannot point to a written rule that says which tools may touch a trial balance.
3. Financial advisor before a review meeting. Copilot answers a question about a client's portfolio from a folder the whole office can open. The junior who asked did not need that file. You are the one who has to explain the folder to the client.
4. Insurance agency on a renewal. A claim note goes into a free AI chat so the summary is faster. Your carrier's renewal form asks which AI tools your team uses. You do not have a written answer, and the renewal meeting is this week.
5. Bookkeeper closing a client's books. Your bookkeeper pastes a bank download into a public chat to "match the categories." The account numbers leave the firm. You still have to hand the books to the accountant who signs them.
6. Tax practice on a deadline night. A preparer pastes a client's notice into a public tool to draft the reply. The notice has a social insurance number on it. You wanted the letter done. You did not want that number in a chat log you cannot pull back.
7. Wealth manager before a family meeting. An associate asks a public tool to summarize a client's trust. The summary is fast. The trust terms are now outside the firm, and you still sit across from that family tomorrow.
8. Consulting firm the night a proposal is due. Your team pastes the client's problem statement into a public tool to rough the deck. The problem statement was under NDA. The deck reads better. But you can't say the work stayed inside the firm anymore.
9. Architecture firm the night a deadline moves. Drawings and a client brief go into a public tool to draft the email. You wanted the hour back. You did not want the brief, or the drawing notes, in someone else's model.
10. Engineering firm before a stamp. A designer pastes a spec section into a public chat to check the wording. The spec names the site and the client. You still stamp the drawing, and you still own what left the building.
11. Marketing agency with a client's unreleased campaign. A writer pastes the launch copy into a public tool to punch up the headline. The campaign is still embargoed. You have to tell the client the draft left the agency.
12. Property manager with a tenant file. A coordinator pastes a complaint, with the unit number and the tenant's name, into a free chat to "make it shorter." You still have to answer to the owner, and the file is no longer only in your system.
13. IT provider logging into a client's tenant. Your technician pastes an error, with the client name in the path, into a public chat to get a fix. You bill for the hour. The client's name is now in a public chat log.
14. HR consultant with a termination draft. Your consultant pastes a client's draft letter, with the employee's name, into a public tool to soften the tone. You still have to stand behind that letter, and the name is no longer only in the file.
15. Real estate brokerage before an offer. An agent pastes a client's offer terms into a public tool to clean the email. The price and the conditions are now outside the brokerage. You still have to explain that email to the client.
