# Sources

> Ground every reply in live data. Toggle Web, Deep Research, Reddit, X, Academic, or GitHub from the @ menu.

By default Foundry answers from the model's training knowledge. Toggle on a **Source** and the model goes and looks something up first — then cites what it found under the reply.

Type `@` in the composer to open the Sources menu.

## Built-in sources

| Source                 | Best for                                                 | Page                              |
| ---------------------- | -------------------------------------------------------- | --------------------------------- |
| **Web Search**         | General fresh facts, news, product pages                 | [Web](/foundry/sources/web)       |
| **Reddit Search**      | Real-people opinions, anecdotes, troubleshooting threads | [Reddit](/foundry/sources/reddit) |
| **Academic Search**    | Papers, peer-reviewed work, scholarly answers            | —                                 |
| **GitHub Search**      | Code references, repos, issues                           | —                                 |
| **X Search**           | Breaking news, tech announcements, real-time sentiment   | [X](/foundry/sources/x)           |
| **Prediction Markets** | Polymarket / Manifold-style probability signals          | —                                 |
| **Schedule**           | Anchor the prompt to a specific date/time window         | —                                 |

For **Deep Research** — the multi-step grounded answer — switch to that **mode** via `/` instead of toggling a single source. See [Deep Research](/foundry/sources/deep-research).

## How toggles work

Toggle one or more sources from the `@` menu. Your **next message** is grounded in those sources; toggles reset when you switch chats.

Foundry shows a **Sources pill** above the composer for every active source so you always know what your next prompt will hit.

## Citations

Every reply that used a source gets **citations** under the answer — clickable links to the source pages, with a short excerpt that the model leaned on.

## Tips

* **Stack sources** for harder questions. *Web + Reddit* gives you both the facts and the lived experience.
* **Reset between chats.** Sources don't bleed across chats by design.
* **Use Deep Research** when one round of search isn't enough. It fans out, reads, and synthesizes.
