Stanford researchers publish independent analysis of how people use AI

Stanford PhD candidate Anka Reuel and collaborators from MIT and other institutions created the AI Observatory, a public platform analyzing 24,521 real conversations with ChatGPT, Claude, Gemini, and Grok collected between 2023 and 2025 with user consent.
AI companies like Anthropic and OpenAI publish their own usage reports based on millions of conversations, but researchers say these reports only show data the companies choose to release, leaving major blind spots.
