OP here.

I built this because I was tired of manually copy-pasting emails into Notion or dealing with Zapier scenarios that just dumped raw HTML strings.

The Stack:

Chrome Extension (Manifest V3)

Node.js backend

OpenAI API for the parsing logic

Notion API

How it works: It grabs the DOM of the active email thread, cleans the noise, sends it to the LLM to enforce a JSON schema (Summary, Action Items, Dates), and pushes it to a Notion Database.

Business Model: It's a paid tool ($9/mo) because parsing long email threads with attachments eats up tokens, and I wanted a sustainable model.

If anyone wants to test the workflow, I made a code for 50% off for HN readers: FOUNDER50

I'd love to hear your feedback on the extraction quality.
