# Configuring entity type synthesis options

{% hint style="info" %}
**Required dataset permission:** Edit dataset settings

When Tonic Textual generates replacement values, those values are always consistent within the dataset. Consistency means that the same original value always produces the same replacement value.

You can configure how Textual generates the replacement values for each entity type.

You can also configure synthesis options from the [Textual Agent](/textual/textual-agent/textual-agent-about.md).
