Arriving 2026
Your private health twin, in your pocket. It knows your whole story, thinks with a panel of frontier AIs, and talks you through real care — with the devices you own. Private by physics.
Universal essential health — coming to Earth first.

What Aion does
One private app that holds your whole health story, reasons over it with a panel of frontier AIs, and is there in the moment you actually need help.
Labs, vitals, meds, conditions, wearables — woven into one private health graph on your phone. It surfaces the connections no single record shows.
Ask a health question and a panel of frontier AIs — Claude, GPT, Gemini — answer together, weighed against graded medical evidence. De-identified before anything leaves your device.
Register the gear you own — a tourniquet, an AED, an EpiPen. When it matters, Aion talks you through the procedure by voice, using validated clinical protocols. Fully offline.
Aion guides; it does not replace emergency services. In a life-threatening emergency, call your local emergency number.
Get Aion
Download once, free. It becomes the full app the moment you’re ready, and steps up to fully-managed when you’d rather not think about it. Same app, same private foundation — no second download.
Your health graph, on-device AI, and offline Kit walkthroughs. Private, no account, nothing to pay.
The complete experience — the multi-model Chorus, health briefings, clinical reasoning and voice — on AI keys you add.
The same full app with the Chorus fully managed. All models included and tuned — no keys to find or add.
Every plan de-identifies your data before any model sees it — no health data ever lives on our servers.
