# Synthesis

> How Ontora turns raw transcripts into cartography, roadmap, and personas.

When a campaign reaches `completed`, Ontora runs a synthesis pipeline that converts the transcripts into four structured artifacts.

## Cartography

A map of the processes that came up in conversation, grouped into categories, with statistics on how often each was mentioned and which contacts mentioned it.

```bash theme={null}
curl https://api.ontora.com/v1/interviews/$ID/cartography \
  -H "X-API-Key: $ONTORA_API_KEY"
```

Use cases:

* Visualize the "shape" of a function in a process map UI.
* Identify processes mentioned by every contact (consensus) versus a single contact (edge cases).

## Roadmap

Proposed solutions grouped by horizon. Each phase contains opportunities sized by impact and effort.

```bash theme={null}
curl https://api.ontora.com/v1/interviews/$ID/roadmap \
  -H "X-API-Key: $ONTORA_API_KEY"
```

Use cases:

* Hand straight to a product team as a starting point.
* Filter for "now" horizon to seed a next-sprint backlog.

## Personas

Per-contact behavioral profiles, optionally rolled up by department. Each persona captures observed characteristics, motivations, and frustrations grounded in the transcript.

```bash theme={null}
curl "https://api.ontora.com/v1/interviews/$ID/personas?department=Operations" \
  -H "X-API-Key: $ONTORA_API_KEY"
```

## Conversations

A list of individual transcripts with one-paragraph summaries and metadata.

```bash theme={null}
curl "https://api.ontora.com/v1/interviews/$ID/conversations?status=completed" \
  -H "X-API-Key: $ONTORA_API_KEY"
```

For the full transcript text, see [Export transcripts](/guides/export-transcripts).

## When does synthesis run?

Synthesis triggers automatically when the last conversation in a campaign reaches `completed`. You'll receive a [`synthesis.completed`](/webhooks/events) webhook when it's ready.

To re-run synthesis (for example after editing the question set), call the campaign's resync endpoint or wait for the next scheduled run.

## Grounding

All synthesis is grounded — every assertion in the cartography, roadmap, and personas can be traced back to specific chunks in the source transcripts. The [GraphRAG query endpoint](/guides/query-with-graphrag) returns those citations directly.
