In other words, approximately 3 in 4 people working in PR now use tools like ChatGPT and DALL-E as part of their workflow. And a further 13% intend to explore its potential.

Of the remaining 12% of respondents, half are undecided, while half will not consider using generative AI in their marketing role. This anti-generative AI stance has softened since 2023, when 15% refused to use it and a further 24% were unsure.

How is AI Being Used in Marketing?

PR professionals are increasingly broadening the scope of AI in their daily tasks.

In 2025, brainstorming is the most popular AI use case for people working in PR, with 82% opting to outsource idea generation.

Not far behind, writing a first draft (72%) and editing/refining drafts (70%) make up the rest of the top three.

At the other end of the spectrum, just 16% use AI to generate images to accompany content.

Here’s a full breakdown of how generative AI is being used in PR workflows:

The average PR professionals complete 5 distinct types of tasks with AI assistance. This is up from roughly 3 tasks in 2024, showing that not only is adoption going up, but also the breadth of usage.

Even among those using AI to generate text, editing remains very common – 89% PR professionals say they always edit AI‑generated text. That’s down from 95% in 2024.

In terms of editing quantity, 51% change most AI-generated content, while 37% claim to make edits to some paragraphs.

However, the extent of editing in published marketing materials is debatable. A Substack analysis of popular newsletters found that 10% likely use AI content. As many as 7% rely “significantly” on AI-generated work, yet many authors downplay their usage.

While that remains a relatively small proportion, the majority of Substack publishers now use AI in their research (64.94%).

Policy, Training, and Corporate Readiness

Despite this high adoption and positive reception, more than half of PR professionals (55%) report that their companies have yet to establish formal policies or guidelines around AI use.

In 2024, the percentage lacking these policies was even higher at 72%, indicating some improvement, but many still operate without structured guidance.

As of 2025, 17% of PR pros state that their organization lacks AI guidelines but has plans to implement them.

When it comes to AI training, there has also been progress. Approximately 1 in 3 (35%) of PR professionals note that training is now offered at work – that’s a 14% increase on 2024’s figure.

That said, there is still some way to go, as 2 in 5 companies don’t offer any form of AI training, down from 50% last year.
