ChatGPT plugin in Ruby - Airport information

ChatGPT plugin that returns airport information in Australia, written in Ruby/Sinatra.

Airport information was downloaded from https://ourairports.com/countries/AU/ and is stored in data/au-airports.csv.

Example usage

Ask for a flight plan between some town airports.

flight-plan

skyvector

It correctly uses the town's local airport GPS coordinates, not the towns' themselves.

sthelens

You can also ask for heading and time to fly, which ChatGPT can help do the calculation.

duration

Run locally and test on ChatGPT

To start up the application and bind to port 9292:

bundle
rerun rackup

You will need to expose the application to the internet. I use https://ngrok.com/.

ngrok http --region=au 9292

The output shows you your domain

Session Status                online
Region                        Australia (au)
Forwarding                    https://e92baeb18b8a.ngrok.app -> http://localhost:9292

The domain e92baeb18b8a.ngrok.app will be passed to ChatGPT when we register the plugin.

Register plugin with ChatGPT

Open https://chat.openai.com/chat, and switch to the ChatGPT "Plugins" model.

setup-model-plugins

Next, under the Plugins dropdown, select "Plugin Store".

setup-open-plugin-store

At the bottom of the modal, click on "Develop your own plugin".

Click the green "My manifest is ready" button.

Copy your ngrok domain e92baeb18b8a.ngrok.app into the form, and click the green "Find manifest file" button.

ChatGPT will validate the two manifest files. Click the green Next button.

Next, click Install for me, then Continue, then Install plugin.
