7This script allows you to:
8- Send emails to OpenAI. The text will be treated as the prompt
9- Parse PDF attachments and include their contents in the AI's analysis.
10- Get response directly to your inbox.
141. Copy this Val and save it as an Email Val (choose Val type in top-right corner of editor)
15
162. Add your OpenAI API key to line 8 (or use an environment variable: https://docs.val.town/reference/environment-variables/)
17
183. Copy the email address of the Val (click 3 dots in top-right > Copy > Copy email address)
