The purpose of this repo is to showcase a contextual AI assistant built with the open source Rasa framework.
Sara is an alpha version and lives in our docs (temporarily she's unavailable on the docs due to maintenance), helping developers getting started with our open source tools. It supports the following user goals:
- Understanding the Rasa framework
- Getting started with Rasa
- Answering some FAQs around Rasa
- Subscribing to the Rasa newsletter
- Requesting a call with Rasa's sales team
- Handling basic chitchat
You can find planned enhancements for Sara in the Project Board
To install Sara, please clone the repo and run:
cd rasa-demo
pip install -r requirements.txt
pip install -e .
This will install the bot and all of its requirements. Note that this bot should be used with python 3.6 or 3.7.
Use rasa train to train a model (this will take a significant amount of memory to train,
if you want to train it faster, try the training command with
--augmentation 0).
Then, to run, first set up your action server in one terminal window:
rasa run actions --actions demo.actionsThere are some custom actions that require connections to external services,
specifically SubscribeNewsletterForm and SalesForm. For these
to run you would need to have your own MailChimp newsletter and a Google sheet
to connect to.
In another window, run the bot:
docker run -p 8000:8000 rasa/duckling
rasa shell --debugNote that --debug mode will produce a lot of output meant to help you understand how the bot is working
under the hood. To simply talk to the bot, you can remove this flag.
If you would like to run Sara on your website, follow the instructions here to place the chat widget on your website.

To ensure a standardized code style we use the formatter black.
If you want to automatically format your code on every commit, you can use pre-commit.
Just install it via pip install pre-commit and execute pre-commit install in the root folder.
This will add a hook to the repository, which reformats files on every commit.
If you want to set it up manually, install black via pip install black.
To reformat files execute
