It tries to find a name for your next Saas product! Assuming you want a simple plain name like, say, Square or Medium, and you're cool with another generic TLD besides .com (which is crowded).
You'll need Python3 installed. :)
Download the script. (Go to "Code" then "Download." Unpack the zip and remember where it is.)
Open up terminal. Change directory to where-ever you unpacked the zip.
Activate a Python3 virtual environment and install requirements...
python3 -m venv venv
source ./venv/bin/activate
pip install -r requirements.txt
Run the script with...
$ python3 script.py .app .dev < words.txt
Any words that appear will have been found to be available under ALL suffixes.
So like, if "wheat" appeared, it would be available under BOTH .app AND .dev.
