Microsoft 365 Copilot reached 15 million paid enterprise seats in Q2 FY2026. Despite that broad rollout, its voluntary usage conversion rate sits at just 35.8% among employees who have access, compared to 83.1% for ChatGPT, according to Recon Analytics’ survey of 150,000+ U.S. respondents. Access and actual adoption are two different metrics.
How Many Employees Use AI Tools at Work?
Gallup’s Q3 2025 survey of 23,068 U.S. workers found that 45% used AI at work at least a few times a year, up from 40% in Q2 2025. Frequent use — defined as several times a week or more — rose from 19% to 23% in the same period, while daily use reached 10%.
Usage is concentrated in knowledge-intensive roles. Technology and information systems workers reported 76% AI adoption in their roles, finance workers 58%, and professional services 57%. In contrast, retail (33%), healthcare (37%), and manufacturing (38%) show lower rates — partly a reflection of more frontline, non-desk work in those sectors. As AI tools become browser-native, Chrome’s dominance at 64.86% of global browser traffic positions it as a key delivery channel for web-based AI tools across all these industries.

Most Common AI Tools Used at Work by Task Type
Gallup’s Q2 2025 survey found that chatbots and virtual assistants are the most common AI tool category at work, used by 62% of employees who use AI. AI writing and editing tools rank second at 36%. Coding assistants are used by 14% of the broader AI-using workforce, though that figure rises to 22% among frequent AI users.
| AI Tool Category | % of AI-Using Employees |
|---|---|
| Chatbots and virtual assistants | 62% |
| AI writing and editing tools | 36% |
| AI coding assistants | 14% (22% among frequent users) |
| Data science and analytics tools | ~13% (avg across usage frequency) |

What Employees Actually Use AI For
Research and information access lead workplace AI use at 57% of employees who use AI tools, followed by editing written content (52%), drafting new materials (47%), consolidating information (42%), and generating ideas (41%). These task distributions have remained stable since Gallup’s initial measure in Q2 2024, suggesting the core use cases have settled.

Most Common AI Tools Used at Work for Coding
Among software developers, AI adoption is near-universal. By 2025, 84% of developers report using or planning to use AI tools. Of those who do, 82% use ChatGPT for coding tasks, while 68% use GitHub Copilot — the two most common coding assistants by a wide margin. Google Gemini is used by 47% of AI-adopting developers, and Claude by 41%.
GitHub Copilot has become a standard tool in under two years, with over 20 million users and 1.3 million developers on paid plans. Developers using it complete coding tasks 55% faster than those without it. A full breakdown of platform-level performance numbers is available in our OpenAI Codex statistics guide. Separately, AI tools show shorter user retention than traditional productivity software, as developers frequently switch between platforms depending on the task.
| AI Coding Tool | Developer Adoption Rate | Key Metric |
|---|---|---|
| ChatGPT | 82% | Top tool for writing and debugging code |
| GitHub Copilot | 68% | 20M+ users; 55% faster task completion |
| Google Gemini | 47% | Gemini Code Assist in Android Studio, Colab |
| Claude AI | 41% | 21% of global LLM API usage; popular for code review |
| Microsoft Copilot | 31% | Embedded in VS Code with Copilot Chat |
| Amazon CodeWhisperer | 4% | 57% faster task completion in AWS environments |

How AI Tools at Work Save Time
ChatGPT users save an average of 1.5 to 2.5 hours per week on writing, research, and problem-solving tasks, according to FlexOS research. Microsoft 365 Copilot users save roughly 30 minutes per week specifically on email, and complete documents 12% faster, per Microsoft-backed productivity research.
The gains are most pronounced in software development. Developers report saving 30–60% of their time on coding, testing, and documentation tasks when using AI tools. GitHub Copilot users complete 126% more projects per week compared to manual coders in some tracked environments. For a direct comparison of how AI-integrated platforms stack up in practice, see our look at business productivity on ChromeOS vs. Windows.
At the macroeconomic level, industries with high AI exposure saw productivity grow 27% between 2018 and 2024, compared to just 7% in sectors with low AI adoption. Companies report three times higher revenue growth per employee when AI is deeply integrated. For context on the cloud platforms powering this growth, see our cloud market share breakdown.
Most Common AI Tools Used at Work: Enterprise Adoption
Fortune 500 penetration of ChatGPT reached 92% in 2025, up from 80% in late 2023. ChatGPT Enterprise seats totaled 1.5 million as of March 2025 — a 10x increase year-over-year. Microsoft 365 Copilot added seats rapidly, reaching 15 million paid enterprise users in Q2 FY2026.
Small businesses are also moving fast. Around 89% report using AI for daily tasks including content creation, scheduling, and customer communications. Only 40–42% have formal AI strategies in place, which points to widespread informal adoption. Organizations deploying cloud-first enterprise devices report lower friction when rolling out browser-based AI tools to distributed teams.
| Segment | AI Adoption Metric | Primary Use Cases |
|---|---|---|
| Fortune 500 (ChatGPT) | 92% penetration | Writing, research, customer service, coding |
| Enterprise (M365 Copilot) | 15M paid seats | Email, meetings, Office productivity |
| Mid-market | ~78% using at least one AI tool | Automation, content, data analysis |
| Small businesses | ~89% for daily tasks | Content creation, scheduling, communications |
