Eir Open builds open-source AI tools that put people in control of their own health data. Named after the Norse goddess of healing, we believe healthcare AI should be private, transparent, and clinically useful.

• Agent Harness — Core infrastructure for health-focused AI agents (tool loop, skills, health memory)
• Health Data Standard — An open YAML-based format for structuring health records, optimized for LLMs and privacy
• Health Skills — Reusable medication lookup and drug interaction tools (Swedish FASS + US FDA)
• Open Medical Scribe — AI-powered clinical transcription that runs locally
• Eir Apps — macOS, iOS, and Chrome extension for managing personal health records with AI

• Privacy-first — Health data stays on the user's device, not in the cloud
• Clinically accurate — We preserve medical context and follow healthcare standards
• Open and modular — Swap LLM providers, transcription engines, and data sources freely

We welcome contributors of all backgrounds — developers, clinicians, researchers, and anyone who cares about health data ownership.
