# PDFs and Web Pages

> Point Drift at a PDF or URL and it will read the document to answer questions, extract values, and use the content while building

Drift can read PDFs (datasheets, spec docs, papers) and web pages (vendor pages, GitHub READMEs, tutorials) directly. Point it at a file or URL and it'll extract the parts relevant to your prompt — dimensions, part numbers, code snippets, protocol details — without you having to copy-paste.

## PDFs

Attach a PDF path (local or URL) the same way you'd reference a file, and ask a question:

```drift theme={null}
/home/you/datasheets/dynamixel-xl430.pdf what's the stall torque and no-load speed for this actuator, and set it in the URDF
```

```drift theme={null}
read /home/you/papers/mpc-quadruped.pdf and summarize the cost function they use
```

Drift decides internally whether to answer from a focused read (fast, cheap) or a full read (thorough). You don't have to pick.

<Info>
  **Password-protected PDFs are supported.** If the PDF is encrypted, Drift decrypts it server-side before reading. No extra flags needed.

## Web pages

Give Drift a URL — Drift fetches the page, reads it, and answers:

```drift theme={null}
https://github.com/google-deepmind/mujoco_menagerie/tree/main/unitree_go2 use this model in a mujoco scene with an IMU on the base
```

```drift theme={null}
what's the latest supported Python version for ROS 2 Jazzy? check the official docs
```

If you don't know the exact URL, ask Drift to search:

```drift theme={null}
find a well-cited paper on differential-drive kinematics with wheel slip and use its formulation
```

## What's blocked

For safety, Drift refuses to fetch:

* Private IP ranges (`10.*`, `192.168.*`, `172.16-31.*`, `127.*`) and other internal-network targets
* `file://` and other non-http(s) schemes

Public URLs on the internet work; anything that would target your local network or filesystem won't.
