- The use of AI in the workplace has almost tripled repeatedly across global office environments since 2023
- ChatGPT lost significant market share as competing workplace AI tools expanded rapidly
- Google Gemini proved to be ChatGPT’s strongest challenger in professional productivity workflows
The adoption of AI in the workplace has entered a phase of extraordinary acceleration across global office environments, as the total time spent using AI tools nearly tripled between 2023 and 2024, before repeating the explosive growth into 2025.
A new report from DeskTime analyzed anonymized data from more than 50,000 users over three years, revealing increasing competition with ChatGPT in workflows.
ChatGPT, which had an astounding 99.91% of all tracked AI time back in 2023, has seen its monopoly shattered significantly as ChatGPT’s share fell to 74.71% during the first four months of 2026, according to DeskTime, which tracked power users who log at least 26 hours a year.
A once dominant player loses his grip
Although a large number of offices still have ChatGPT in their workflows, super users loyal to ChatGPT dropped from 100% to 75.61% during the same period.
This erosion mirrors what previous Internet users saw as Firefox gradually lost ground to newer alternatives.
“With artificial intelligence, it’s often hard to separate hype from reality, so DeskTime decided to investigate what’s really going on in today’s workplace,” said Artis Rozentals, CEO of DeskTime.
“The numbers are compelling…AI is fundamentally redefining work, and the risk of falling behind is growing exponentially.”
Gemini and Claude remain ChatGPT’s biggest rivals
Google’s Gemini has risen to become the primary contender among workplace AI tools by capturing 14.38% of office AI time recorded so far in 2026.
Claude has taken an even more dramatic rise, now accounting for 8.56% of consumption and showing the steepest upward curve this year.
Both rivals have converted random subjects into repeat users at a rate that ChatGPT can’t match.
However, Microsoft’s Copilot presents a puzzling contrast, as its share has stagnated at around 1% over several years.
Neither growth nor collapse seems to characterize this tool’s trajectory within office environments.
Meanwhile, a category of lesser alternatives, including Perplexity and Mistral, have failed to gain any meaningful foothold.
The market for AI agents in the workplace increasingly resembles a three-horse race rather than a one-player field, and workplace professionals are actively diversifying their toolsets rather than sticking to a single, familiar interface.
These numbers come from a single productivity tracking service and may not represent a widespread narrative of AI usage.
The definition of “AI time” can vary across different job functions and industries in ways that distort competitive comparisons.
Nevertheless, the current trend seems consistent enough to warrant the attention of any dominant software provider.
Whether ChatGPT can reverse this decline or will follow Firefox to niche status remains an open question for the rest of 2026.
