Your data. Your AI. Your longevity plan.
Longeviti turns blood work and daily tracking into an adaptive longevity plan — meals, supplements, coaching. The app does zero AI compute. Your own AI assistant — Claude, Codex, or any Claude-compatible CLI — generates plans that conform to our open schemas. Your data stays in your Google Drive. We never see it.
How it works
Longeviti is two things working together: a Flutter app on your phone, and a set of Claude Code skills that act as your nutritionist, coach, and plan author.
Sideload the app
Download the Android APK from our releases. Sign in with Google and grant Drive access. (iOS coming later.)
Clone the framework
Pull the longeviti-framework repo — it holds the skills that author your plan.
Run /onboard
Drop in your health reports. Claude reads them and writes your profile, plan, and rules to Drive.
Track and evolve
Log meals in the app. Run /elara weekly — it coaches you and updates plans as your health changes.
Bring your own AI assistant
Longeviti the app is a renderer and logger — it reads plans, shows meals, logs tracking. All the reasoning — reading your reports, generating plans, producing coaching — runs in your AI assistant's session, on your machine, billed to your account. We publish the schemas; your AI writes files that conform.
Render & log
Renders your weekly plan. Logs daily tracking. Checks food compliance against a deterministic rule engine. Zero LLM calls.
Reason & author
Reads your reports. Writes your profile. Generates plans + rules. Produces weekly coaching. All via skills you run locally.
Open schemas
Four JSON Schemas define what a plan, profile, coaching session, and rules file look like. Your AI writes to spec; the app renders.
What you get
Weekly meals + supplements
Generated from your blood work, conditions, and goals. Updates automatically as new reports arrive.
Meals, vitals, workouts
Four-ring daily summary. Offline-first, auto-synced to Drive, no account required beyond Google.
Weekly insights from ELARA
Adherence patterns, swaps, red flags, and plan directives — produced by a senior-nutritionist prompt.
Compliance at a glance
Every food is checked against your active rules — green dot if it fits, amber if it's borderline, red if not.
Zero-server architecture
All plans, tracking, and reports live in .app/longeviti/ on your own Google Drive.
Inspect and extend
The JSON schemas, skills, and rules are public and MIT-licensed. Bring your own nutritionist's protocols and wire them in.
