Digital technology leads in volume (30% of queries), but fields like Marketing, Sales, and Management show more "stickiness." Once these users adopt an agent, their usage intensity outpaces their adoption numbers as they integrate the assistant into their daily workflow.

Most agent queries come from personal use (55%), followed by professional (30%) and educational (16%) contexts. New users often start with low-stakes questions like travel or trivia. Over time, they shift to more complex topics like productivity, learning, and career advice.

More than half of all agent activity focuses on cognitive work. Agent use is dominated by Productivity & Workflow (36% of queries) and Learning & Research (21%). Users rely on the assistant to think through something, synthesize findings, and take action on those learnings.

Harvard and Perplexity researchers conducted the first large‑scale field study of how people use AI agents. We analyzed hundreds of millions of anonymized user interactions in Comet to answer three questions: who’s using agents, how much, and what for. https://t.co/w9YrAKdvqz

Prompt injection involves embedding malicious instructions in text read by AI agents, altering its behavior unnoticed. Attackers hide this in comments, templates, footers, or invisible HTML elements parsed by agents but unseen by users.
