# Your own internal agent

> Your team can ask an agent you built questions inside Plain, in the same place they ask Sidekick.

An agent you bring is not limited to answering customer threads. Your team can ask it questions in the same place they ask [Sidekick](/product/agents/sidekick). Plain records the discussion and shows the agent's tool calls as it works, while your own infrastructure runs the agent.

Nothing an internal agent writes reaches the customer. The discussion is internal to your team.

## What it can do

Your agent gets the same tools Sidekick uses for the in-app experience. It can be invoked automatically by a [workflow](/product/workflows), show its tool calls as it works, send messages, and gate sensitive actions behind user approval.
