A global survey of more than 2,000 marketing leaders across seven markets, released June 30, 2026 by Optimizely, shows that AI is helping teams produce more - but the time savings promised by automation are being swallowed by a growing "revision tax." Seventy-six percent of marketers now spend at least three hours each week editing, fact-checking, or correcting AI-generated output, and only 4% say AI saves time at every stage of the process.
The study, conducted by Savanta, found that fact-checking and hallucination review created more extra work than any other factor, cited by 48% of respondents. Forty percent pointed to time lost moving information between disconnected systems. Only 19% of marketers work from a single integrated AI platform, while most navigate a patchwork of tools that add friction rather than removing it.
Speed versus quality: compromises most organizations aren't talking about
Under deadline pressure, 25% of marketers admit they frequently or always publish AI-generated content they know is not fully on-brand. Thirty percent say they frequently or always pass off AI-generated work as their own human-created original work. These compromises suggest that the push for efficiency is undercutting the very brand distinctiveness marketing is meant to protect.
The findings also reveal that only 30% of marketers believe their brand voice is genuinely unmistakable. Fifty-three percent say current AI tools can capture the facts of a brand but struggle to capture the emotional resonance that connects with audiences. And 46% believe heavy AI reliance could erode creative skill development among junior marketers.
The widening gap between C-suite and operational reality
More than half (54%) of marketers say leadership underestimates the human effort required to make AI-generated work usable. While 69% of C-suite leaders say AI adoption is fully aligned across their organization, only 27% of analysts who do the day-to-day work agree. The farther removed from execution, the rosier the picture becomes.
That disconnect extends to behavior. Among C-suite leaders, 44% say they frequently or always pass off fully AI-generated work as their own - the highest rate of any seniority level and nearly double the figure for managers (23%). The people setting the AI mandate are also the most likely to quietly outsource their own output to it. This disconnect may help explain why 65% of marketers would pause or adjust their company's AI rollout to strengthen guardrails, improve governance, or rethink the operating model. As marketing teams work through the strategic challenges of AI integration, AI for Marketing resources can help bridge the gap between leadership expectations and team reality.
The revision tax puts a ceiling on creative work
Thirty-nine percent of marketers say they are too busy managing workflows, outputs, and day-to-day demands to spend enough time thinking strategically or developing new ideas. When the hours AI saves are immediately claimed by reviewing and reworking its output, the promised creative headroom never materializes. Fifty-one percent say they are at least slightly worried that AI is contributing to a growing "sea of sameness" across brands.
"AI was supposed to give marketers room to think. What most teams got instead was more to manage," said Tara Corey, SVP of Marketing at Optimizely. "When the pressure doesn't stop and the infrastructure isn't there, everyone improvises. The corner-cutting, the off-brand content, the invisible hours - that's what happens when ambition outpaces infrastructure. The good news is that's a solvable problem."

Why this matters for marketers
The study clarifies that AI adoption is not delivering the strategic space marketers were promised. Instead, it's shifting time from creation to correction and quality control. For leaders, the data suggests that the next phase of AI value will come not from producing more, but from building the infrastructure and governance that let teams reclaim time for strategy and human-led creativity. The C-suite's overly optimistic outlook, when compared to the reality of analysts and managers, points to a need for better alignment across reporting lines. AI Learning Path for CMOs offers a way for senior leaders to close that perception gap and set up teams for sustainable, creative output rather than endless revision loops.
