AI in client work: disclosure, confidentiality, and who owns the deliverables

AI tools are now part of how a lot of freelance work gets done, and clients have noticed. Contracts, onboarding forms, and procurement questionnaires increasingly ask whether you use AI, which tools, and what happens to the client's material when you do. Three questions sit underneath: do you need to tell the client, is their information safe, and do they actually own what you deliver.

The short answer: follow any AI terms in the client's contract, keep confidential material out of tools the client hasn't approved, and don't promise copyright in material a tool generated. This briefing covers each point, with a sample AI-use clause, a disclosure line for proposals, and a checklist to run before your next project starts.

What clients are asking for

AI terms in client contracts vary widely, but they tend to fall into a few types. Read for each of these when a new agreement arrives:

• Disclosure: you must tell the client if, where, or how AI tools were used.
• Approval or prohibition: AI may be used only with prior written consent, only with named tools, or not at all.
• Data handling: confidential information and personal data must not be entered into third-party tools.
• Originality warranties: you promise the work is original, does not infringe, and that the client will own it outright.

The last type is the one to watch. A warranty written before AI tools were common can promise more than you can deliver if part of the work was generated rather than authored. The guide to freelance contract clauses covers how IP, warranty, and indemnity clauses interact.

Confidentiality: what you paste matters

Pasting a client's brief, data, code, or draft into an AI tool sends it to a third party. Whether that breaches your NDA depends on the agreement and on what the tool does with inputs. Before you use any tool on client material, check its current terms and settings for:

• whether inputs can be used to train or improve the provider's models, and whether you can turn that off;
• how long inputs and outputs are kept, and who at the provider can see them;
• whether the terms differ between free, paid, and business plans.

These settings change, so check them on the provider's own pages rather than relying on memory. When in doubt, remove names and identifying details, use dummy data, or ask the client which tools they have already approved. Record the tools and settings you use in your solo operating system so you can answer a client questionnaire in minutes.

Ownership and human authorship

In the United States, the Copyright Office's report on copyrightability, published January 29, 2025, concluded that AI outputs can be protected only where a human author has determined sufficient expressive elements. Using AI as a tool does not bar protection, and human-authored material, creative selection and arrangement, and human modifications can be protected. Prompts alone, given the technology available at the time, are not enough.

The courts have taken the same line. In Thaler v. Perlmutter, the D.C. Circuit held that human authorship is required, and the Supreme Court declined to hear the case on March 2, 2026. The Copyright Office's registration guidance also says applicants have a duty to disclose AI-generated content in works they register.

What this means for a "you own the deliverables" clause: you can only assign rights that exist. If a logo, image, or block of text was generated with little human input, there may be no copyright in it for you to transfer, and a competitor could reuse it. Clients who need exclusive, protectable work should know which parts were authored and which were generated, and you should avoid warranting full copyright ownership of material that may not have it.

The UK position differs. Section 9(3) of the Copyright, Designs and Patents Act 1988 treats the author of a computer-generated work as the person who made the arrangements necessary for its creation. In its March 2026 report on copyright and AI, the UK government said that, without evidence of its ongoing value, this protection for wholly computer-generated works should be removed, while AI-assisted works would stay protected. That is a proposal, so check whether the law has changed before relying on section 9(3).

Sample AI-use clause

A starting point to adapt for your own agreements and have reviewed. It allows tool use, protects confidential material, and keeps the ownership promise accurate.

AI tools. Freelancer may use software tools, including AI-assisted tools, to support research, drafting, and production. Freelancer will:
(a) not enter Client Confidential Information or personal data into any AI tool unless Client has approved that tool in writing, and only with settings that prevent the provider from using the inputs to train its models where such settings are available;
(b) review, edit, and take responsibility for all Deliverables, whether or not AI tools were used;
(c) on request, tell Client which tools were used and for which parts of the work.

Ownership. On full payment, Freelancer assigns to Client all rights Freelancer holds in the Deliverables. Client acknowledges that material generated by an AI tool without sufficient human authorship may not be protected by copyright, and that this assignment covers such material only to the extent rights exist in it.

If a client prohibits AI entirely, agree to it only if you can work that way, and price the work accordingly. Add the clause to your statement of work template so the scope and the tool terms are signed together. For ongoing work, put the same terms in your freelance retainer agreement, where the tools you use may change during the engagement.

A disclosure line for proposals

Saying it up front answers the question before procurement asks it, and it reads as a process rather than a confession.

How I use AI tools: I may use AI-assisted tools for research, first drafts, or routine production steps. I never put your confidential material into a tool you haven't approved, and every deliverable is reviewed, edited, and owned by me before it reaches you. If your organization has an AI policy, send it over and I'll work within it.

Place it in the process or terms section of your freelance proposal template, and only promise what you actually do.

Checklist

1. Read each active contract for AI terms. Note disclosure duties, approved tools, and bans.
2. List the tools you use. For each one, record the plan, the training and retention settings, and the date you checked them.
3. Set a data rule. No client confidential information or personal data in unapproved tools.
4. Check your IP and warranty wording. Make sure it does not promise copyright in generated material.
5. Keep a light record of authorship. Drafts and edit history show the human work if ownership is ever questioned.
6. Add the disclosure line. Put it in proposals and onboarding so clients hear it from you first.

Onboarding is the natural moment to ask for the client's AI policy and approved tools; the client onboarding and delivery guide covers the kickoff and onboarding checklist where that question fits. And if a new contact asks for ID documents, bank logins, or tax numbers before any contract exists, run through the red flags for fake client scams first.
