Harvard and Perplexity analyzed hundreds of millions of anonymized Comet interactions to map how people use AI agents. Key findings: more than half of activity is cognitive—Productivity & Workflow (36%) and Learning & Research (21%). Most queries are personal (55%), then professional (30%) and educational (16%). Users shift from low‑stakes to productivity and career use; certain fields show higher stickiness.
