Governed patient agents. Open foundation, hospital-grade.
The same principle that governs provider data governs patient-facing AI: capture the signal, keep a human in the loop, and produce a record an organization can defend. Tula is the open-source foundation. Aria is the commercial, governed platform hospitals run at scale.
Tula. Your health. Your data. Your AI.
Tula turns a general-purpose AI agent into a personal health intelligence assistant. It runs in a private, self-hosted workspace, so health data stays under the user's control - no closed cloud health platform, no third-party data sharing.
- health-records - pull medical records from patient portals via SMART on FHIR
- prep-my-visit - IPS-aligned visit prep grounded in the patient's chart
- Lookout for me (myhealth-pulse) - curated digest across health feeds and signals
- Plus med-pdf, epic-note, memory-diff, and more in the open-source repo
High-value skills · open source
Tula is an open-source tool for personal health organization and health literacy. It is not a medical device, not clinical decision support, and not a substitute for professional medical advice, diagnosis, or treatment.
Tula and Aria, in action.
A short walkthrough: pulling records from a patient portal, visit prep, Lookout for me, and how Aria governs model calls with an audit trail.
Aria. Governed patient agents at hospital scale.
Aria extends the Tula skill layer with the enterprise infrastructure a health system needs to run patient agents safely: each patient can have a dedicated agent operating within organizational policy, consent rules, identity boundaries, and approved workflows.
Identity, consent & role-based governance
Every agent action scoped to policy, with patient consent and access controls built in.
Governed Tula skills at scale
Enable and scope the same open-source skills - health-records, prep-my-visit, Lookout for me (myhealth-pulse) - under hospital policy.
Audit, evaluation & LLM-gateway governance
A continuous record of oversight, with a governance score a quality officer can act on.
For hospital technology and security leaders: RealActivity is partnering with Anthropic (in progress) to offer governed Claude Mythos Preview for defensive code and systems review on the same harness. See Advisory.
