# Connectors

> Connect a data source and make it actionable

Adapter connects to your data sources, indexes their contents, and runs comprehension over them to extract key facts, entities, and their relationships.
We support a growing list of popular tools out of the box, and you can use a [custom connector](/core-concepts/custom-connectors) to push data directly when you'd rather manage the connection yourself.

## Connecting a source

Adapter handles the parts of ingestion that are tedious to build yourself: authenticating with the source, pulling records, normalizing them, and keeping the index up to date. You configure the connector; Adapter manages the pipeline.

## Comprehension

Adapter's internal processing engine runs over data to identify and resolve the entities and the relationships present, including resolving and deduplicating across sources.

## Sync modes

Adapter supports batch sync to backfill historical data, along with real-time sync that keeps your data up to date.

## Custom connectors

If you'd rather own the integration yourself, create a custom connector and push events directly. See [Custom connectors](/core-concepts/custom-connectors) for the full guide.
