# Build with SDKs

AssemblyAI maintains official SDKs for Python and JavaScript. Both SDKs cover pre-recorded transcription, real-time streaming, and speech understanding, and handle authentication, polling, and retries for you.

## Python

Install the SDK with pip:

```bash theme={null}
pip install assemblyai
```

The Python SDK is open source on [GitHub](https://github.com/AssemblyAI/assemblyai-python-sdk).

## JavaScript

Install the SDK with npm:

```bash theme={null}
npm install assemblyai
```

The JavaScript SDK runs in Node.js and other server-side JavaScript runtimes, and is open source on [GitHub](https://github.com/AssemblyAI/assemblyai-node-sdk).
