Daily archive of AI-tool adoption signals: relative Google-search preference for 13 AI tools across 84 countries (anchor-normalized shares — relative preference, not usage counts), npm/PyPI SDK download counts, GitHub star snapshots, Hugging Face model snapshots, and Wikipedia attention. The country-level daily panel is not reconstructible from primary sources and begins 2026-07-07. Methodology, data dictionary and free JSON API: https://whoisusingai.com/tracker/research. Measures attention/preference and developer-adjacent momentum; contains no vendor telemetry and no personal data.
