# Synapse

> Build deterministic, adaptive assessment and alignment journeys with Synapse SDKs and APIs.

## Docs

- [Introduction](https://synapse-docs.apart.io/index.md): Build governed assessment and alignment journeys with deterministic, version-pinned results.
- [Quickstart](https://synapse-docs.apart.io/quickstart.md): Sync a subject, enroll them, and start a governed participant session from your backend.
- [Platform model](https://synapse-docs.apart.io/concepts/platform.md): Understand tenant scope, immutable scoring science, programs, and evaluation results.
- [TypeScript SDK](https://synapse-docs.apart.io/sdk/typescript.md): Use the typed server SDK for tenant resources, participant sessions, results, continuous evaluation, and webhooks.
- [Python SDK](https://synapse-docs.apart.io/sdk/python.md): Use synchronous and asynchronous Python clients with Pydantic models, safe retries, and cursor pages.
- [Browser and React SDK](https://synapse-docs.apart.io/sdk/browser.md): Render participant journeys with short-lived, evaluation-scoped tokens.
- [API overview](https://synapse-docs.apart.io/api/index.md): Use the tenant-bound, versioned Synapse API directly from any language.
- [Authentication](https://synapse-docs.apart.io/api/authentication.md): Choose the narrowest credential for the actor and preserve the server/browser trust boundary.
- [Endpoint reference](https://synapse-docs.apart.io/api/reference.md): Browse every operation generated from the canonical Synapse OpenAPI document.
- [Schema reference](https://synapse-docs.apart.io/api/schemas.md): Understand the canonical request, response, event, and error models exposed by Synapse.
