# Ground a reply with Sources

> Get a live, cited answer in 90 seconds.

By the end of this tutorial you'll have asked a question, grounded it in live web + Reddit results, and reviewed the citations Foundry pulled.

## Before you start

* Signed in at [chat.ironlabs.ai](https://chat.ironlabs.ai).

<Note>
  **Screenshot coming.** Captures land in the next pass.
</Note>

## 1. Start a fresh chat

Sidebar → **New chat** (`⌘⇧O`).

## 2. Open the Sources menu

In the composer, type `@`. The Sources menu opens.

## 3. Toggle two sources

Pick **Web** and **Reddit**. Both pills appear above the composer.

## 4. Ask a real question

Pick something that benefits from both general facts and lived experience. For example:

```
What are people saying about the new MacBook Air's keyboard
quality vs the previous gen? Compare reviewer takes with
actual user experience.
```

Hit **Enter**.

## 5. Watch the reply

You'll see Foundry:

* Fire searches against Web (Exa) and Reddit.
* Pull excerpts from the top results.
* Synthesize a reply with **citations** under it.

## 6. Verify the citations

Click any citation to open the source page in a new tab. This is the bit most people skip — it's also the bit that turns a useful answer into a trustworthy one.

## What's next

* **Try Deep Research** for a similar question — *"Now do this as a Deep Research run"* — and compare depth.
* **Stack a connector.** Connect Exa and the same question runs through Exa's heavier search.
* **Pair with browser notifications** so long runs don't tie you to the tab.
