# 🎙️ Pipecat: Real-Time Voice & Multimodal AI Agents
**Pipecat** is an open-source Python framework for building real-time voice and multimodal conversational agents. Orchestrate audio and video, AI services, different transports, and conversation pipelines effortlessly—so you can focus on what makes your agent unique.
## 🚀 What You Can Build
- **Voice Assistants** – natural, streaming conversations with AI
- **AI Companions** – coaches, meeting assistants, characters
- **Multimodal Interfaces** – voice, video, images, and more
- **Interactive Storytelling** – creative tools with generative media
- **Business Agents** – customer intake, support bots, guided flows
- **Complex Dialog Systems** – design logic with structured conversations
🧭 Looking to build structured conversations? Check out [Pipecat Flows](https://github.com/pipecat-ai/pipecat-flows) for managing complex conversational states and transitions.
## 🧠 Why Pipecat?
- **Voice-first**: Integrates speech recognition, text-to-speech, and conversation handling
- **Pluggable**: Supports many AI services and tools
- **Composable Pipelines**: Build complex behavior from modular components
- **Real-Time**: Ultra-low latency interaction with different transports (e.g. WebSockets or WebRTC)

## ⚡ Getting started
You can get started with Pipecat running on your local machine, then move your agent processes to the cloud when you’re ready.
```shell
# Install the module
pip install pipecat-ai
# Set up your environment
cp dot-env.template .env
```
To keep things lightweight, only the core framework is included by default. If you need support for third-party AI services, you can add the necessary dependencies with:
```shell
pip install "pipecat-ai[option,...]"
```
## 🧪 Code examples
- [Foundational](https://github.com/pipecat-ai/pipecat/tree/main/examples/foundational) — small snippets that build on each other, introducing one or two concepts at a time
- [Example apps](https://github.com/pipecat-ai/pipecat/tree/main/examples/) — complete applications that you can use as starting points for development
## 🛠️ Hacking on the framework itself
1. Set up a virtual environment before following these instructions. From the root of the repo:
```shell
python3 -m venv venv
source venv/bin/activate
```
2. Install the development dependencies:
```shell
pip install -r dev-requirements.txt
```
3. Install the git pre-commit hooks (these help ensure your code follows project rules):
```shell
pre-commit install
```
4. Install the `pipecat-ai` package locally in editable mode:
```shell
pip install -e .
```
> The `-e` or `--editable` option allows you to modify the code without reinstalling.
5. Include optional dependencies as needed. For example:
```shell
pip install -e ".[daily,deepgram,cartesia,openai,silero]"
```
6. (Optional) If you want to use this package from another directory:
```shell
pip install "path_to_this_repo[option,...]"
```
### Running tests
From the root directory, run:
```shell
pytest
```
### Setting up your editor
This project uses strict [PEP 8](https://peps.python.org/pep-0008/) formatting via [Ruff](https://github.com/astral-sh/ruff).
#### Emacs
You can use [use-package](https://github.com/jwiegley/use-package) to install [emacs-lazy-ruff](https://github.com/christophermadsen/emacs-lazy-ruff) package and configure `ruff` arguments:
```elisp
(use-package lazy-ruff
:ensure t
:hook ((python-mode . lazy-ruff-mode))
:config
(setq lazy-ruff-format-command "ruff format")
(setq lazy-ruff-check-command "ruff check --select I"))
```
`ruff` was installed in the `venv` environment described before, so you should be able to use [pyvenv-auto](https://github.com/ryotaro612/pyvenv-auto) to automatically load that environment inside Emacs.
```elisp
(use-package pyvenv-auto
:ensure t
:defer t
:hook ((python-mode . pyvenv-auto-run)))
```
#### Visual Studio Code
Install the
[Ruff](https://marketplace.visualstudio.com/items?itemName=charliermarsh.ruff) extension. Then edit the user settings (_Ctrl-Shift-P_ `Open User Settings (JSON)`) and set it as the default Python formatter, and enable formatting on save:
```json
"[python]": {
"editor.defaultFormatter": "charliermarsh.ruff",
"editor.formatOnSave": true
}
```
#### PyCharm
`ruff` was installed in the `venv` environment described before, now to enable autoformatting on save, go to `File` -> `Settings` -> `Tools` -> `File Watchers` and add a new watcher with the following settings:
1. **Name**: `Ruff formatter`
2. **File type**: `Python`
3. **Working directory**: `$ContentRoot$`
4. **Arguments**: `format $FilePath$`
5. **Program**: `$PyInterpreterDirectory$/ruff`
