Transit Platform

Health context for AI agents and third-party tools.

Transit is not only a dashboard. It can also act as the user-owned health data layer for personal AI agents, coaching products and external tools that need authenticated biomarker context, integration state and AI-generated outputs.

What developers get

A practical API story, not platform theater.

Transit exposes the health context external tools actually need right now: normalized biomarker information, wearable sync status, AI outputs and ingestion routes. The goal is simple: let agents and tools reason over a user's health data without rebuilding the full stack.

Health context

Biomarker and reference-profile access

Give external tools the user's current biomarker state, interpretation context and latest meaningful changes.

Sync state

Wearable and ingestion visibility

Read whether Whoop, Strava, Apple Health and other sources are connected, fresh and useful enough for downstream reasoning.

AI outputs

Companion and narrative handoff

Use Transit-generated summaries and recommendations as structured inputs for your own user experience.

Who it is for

Built for tools that want health context, not for enterprise checkbox selling.

The best initial fits are products and builders who already have a user relationship and want to enrich it with grounded health context.

Personal AI agents

A user's personal agent can read Transit context and turn it into proactive weekly nudges, alerts and planning help.

Health and coaching products

Coaching workflows can use Transit as the interpretation layer underneath their own product or service experience.

Specialized tools

Recovery, nutrition and planning tools can plug into richer biomarker and wearable context without building a dashboard from zero.

Example workflows

How Transit can sit inside another product.

Workflow 01

AI coach reads weekly context

An external coach or agent reads recovery, biomarker and adherence context and sends a weekly summary with priority changes.

Workflow 02

Risk signal triggers a product alert

A tool watches for degraded sleep, HRV or biomarker trends and notifies the user before the issue becomes obvious in day-to-day behavior.

Workflow 03

Agent explains lab changes in plain language

Transit provides the context layer and AI output scaffolding so another interface can explain what changed and why it matters this week.

Current API surface

The current public interface in practical categories.

Category 01

Health context

Biomarker points, derived marker status, reference profile and longitudinal context.

Category 02

Integration and sync status

Connected sources, sync freshness, ingestion quality and normalized activity pipelines.

Category 03

AI summaries and recommendations

Transit Companion outputs and narrative layers that can be consumed by downstream tools.

Category 04

Ingestion and bridge flows

Apple Health bridge and other routes that move fresh user data into the Transit context layer.

Onboarding path

The fastest way to get started.

Step 01

Create or use a Transit account

Start with the same user account and dashboard that powers the core Transit product.

Step 02

Connect real user data

Sync wearables, upload labs and make sure the health context is worth reasoning over.

Step 03

Read the relevant categories

Start with health context, sync status and AI outputs before you expand into richer ingestion flows.

Step 04

Ship one focused user workflow

Do one thing well first: weekly summaries, proactive alerts or decision support for a clear user segment.

Primary story

Transit remains B2C-first.

The platform does not replace the product wedge. It extends the same trusted decision layer into other tools after the core user story is clear.

Next step

If you want to build on Transit, start with a real workflow.

Bring one concrete user problem, one current interface and one clear reason Transit should be the health-context layer underneath it.
