AI Transparency

When and how to disclose AI tool usage to clients, and what “substantial use” means in practice.
4 min readReviewed January 2026Annual review

Key points

  • Disclose AI use when it forms a substantial part of your process
  • “Substantial” typically means AI-generated content that goes beyond research or ideation
  • When in doubt, disclose; transparency builds trust
  • Document your AI use for your own records

What the Code says

The ProCopywriters Code of Conduct requires that you “Disclose any substantial use of AI tools in your work when relevant to the client relationship.” But what does “substantial” mean, and when is disclosure relevant?

This guidance helps you interpret and apply this standard in practice. The goal isn’t to create bureaucratic hurdles, but to maintain the trust that makes professional relationships work.

What counts as "substantial" use?

AI use exists on a spectrum. Not every interaction with an AI tool requires disclosure.

Generally doesn’t require disclosure:

  • Using AI for research or fact-checking
  • Grammar and spell-checking tools
  • Using AI to generate ideas that you develop
  • Transcription services
  • Translation tools for reference

Generally requires disclosure:

  • AI-generated first drafts that you edit and refine
  • Using AI to write significant portions of deliverables
  • AI-generated content that appears in the final work with minimal changes
  • Using AI to create content variations at scale

The “could it matter?” test

Ask yourself: if the client knew exactly how you’d used AI, would it change their perception of the work or its value? If yes, disclose.

When to have the conversation

The best time to discuss AI use is before you start work, not after. Consider including your AI policy in:

  • Your terms and conditions
  • Project proposals or quotes
  • Initial client conversations
  • Your website or portfolio

Being upfront about your approach positions AI use as a professional choice, not something to hide.

Tip

Create a simple AI use statement for your website. Something like: “I use AI tools to support research and ideation. All client deliverables are written and edited by me, and I disclose any substantial AI contribution to specific projects.”

How to frame disclosure

Disclosure doesn’t need to be apologetic. Frame your AI use in terms of the value it provides:

  • “I use AI tools to accelerate research, which helps me deliver faster without compromising quality.”
  • “AI helps me explore more variations, so you get a wider range of options to choose from.”
  • “I use AI for initial drafts, then apply my expertise to refine and optimise the content.”

The key is honesty combined with confidence in your professional value.

Watch out for client policies

Some clients, particularly in regulated industries, may have their own policies prohibiting AI use. Always check before assuming disclosure is enough; some contexts require human-only work.

Keeping records

Even when you don’t need to disclose to clients, keeping your own records of AI use is good practice. This helps you:

  • Demonstrate your process if questions arise later
  • Maintain consistency in how you describe your work
  • Reflect on how AI is affecting your practice
  • Provide evidence if disputes arise

A simple note in your project file is usually sufficient — you don’t need elaborate documentation.

Summary

Transparency about AI use isn’t about admitting a shortcoming — it’s about maintaining the trust that makes professional relationships work. When you’re open about your tools and methods, clients can make informed decisions and you can work without worry.

The standard is straightforward: if AI contributed substantially to the work, say so. When in doubt, disclose.
