# Test and improve Aura

> Try Aura in the playground, watch how it performs, and teach it the answers it was missing.

## Test in the playground

The **playground** is a private chat with your agent. Use it to check answers before visitors see them: nothing you send there reaches your inbox or counts as a visitor chat.

The playground, in the agent's side panel.

1. Open an agent from **Aura AI**. Click **Test your AI** at the top of the page, or the playground icon on the right, to open the playground in the side panel.
2. Ask a question your customers often ask.
3. Change a source, a prompt or a setting, then ask again.

> [!TIP]
>
> Trying a question in the playground completes the **Ask Aura a question** step of the [setup guide](https://docs.emplorium.io/get-started/setup-guide.md).

## Overview

**Overview**, under **Review**, shows how the agent is doing:

![The agent Overview tab](https://mintcdn.com/emplorium/ugrIr0OwIbcsQUR_/images/aura/overview.png?fit=max\&auto=format\&n=ugrIr0OwIbcsQUR_\&q=85\&s=0116548fdd9a4d70ac1a41e37d5fb8ee)

Overview: knowledge health, topics, credits and what to do next.

* **Knowledge health**: the state of the agent's sources.
* **Top topics**: what visitors ask about most (appears once Aura has handled chats).
* **AI credits**: what the agent has used.
* **Channels**: where its chats came from.
* **Recommendations**: the next things to fix, such as enabling the agent, adding sources, retrying sources that failed, refreshing stale ones or answering knowledge gaps.

## Knowledge gaps

**Gaps** lists visitor questions Aura didn't have enough knowledge to answer, with how many times each was asked and when it was last seen. Sort them by **Most frequent** or **Most recent**. Fixing them makes Aura better over time.

Gaps: the questions Aura couldn't answer.

1. Open **Gaps** and pick a question to resolve.
2. Write the answer Aura should give the next time someone asks. You can refine the question first.
3. Click **Save answer** to resolve the gap.

For answers that must always be word for word, you can also add a [Question & answer](https://docs.emplorium.io/aura/train.md#question-answer) pair.
