• Node.js >= 18
• an OpenAI API key
• a Postmark server

make init

It will install every dependencies.

Then you can copy the .env.sample file as .env, and fill it with your info:

• OPENAI_API_KEY: your Open API key.
• SUPABASE_URL: the url of your Supabase DB.
• SUPABASE_ANON_KEY: the anon key of your Supabase BD.
• POSTMARK_API_KEY: your Postmark API key.
• DEFAULT_POSTMARK_MAIL: the default email you are using to communicate with the service.

The conversational Agent

Test the interest scrapper (without the mail)

make conv_agent_test

This will return your preferences in a JSON format. If you want to see and change the request, go to the ./conversational_agent/src/test/myMessage.txt.

Send an email an get your extracted preferences !

make conv_agent

This will start the server at http://localhost:3000. Now, in an other terminal :

make start_ngrok

This, will show a bunch of line. Note the one like :

Forwarding                    <YOUR_WEBHOOK_URI> -> http://localhost:3000

Go to your Postmark server, and :

• Create an Inbound Message Stream if not already existing.
• In the settings of this Inbound Stream, write <YOUR_WEBHOOK_URI>/webhook in the Webhook section.
• Be sure that the email you have entered in the .env file as DEFAULT_POSTMARK_MAIL is in Sender Signatures. This will be the email you are going to use after.

Now you can send an email to the inbound address (in the inbound settings). This will return a list of preferences.
