Hi, here is the code for the Desktop Assistant(Rachel) I created as a personal project. Hope you like it!

Navigate to ./src
python3 main.py

Made on python with Tkinter UI, thus compatible with MacOS, Windows, and Ubuntu.
Call Rachel and make it do tasks.
Currently implemented to do basic tasks - dictionary, application launch, stock values, shell commands etc.
All the commands are configurable and can be edited in features with just the modification of text files.
You can add new commands easily with commands.py.
