Dev feeds years-old Notion course to Codex, gets back a full interactive options course
RichardsonDx · x · 2026-10-08
A developer had an options-trading course he built years ago to teach himself, sitting unused in Notion. He fed it to Codex to test this kind of UX, and it came back as a full interactive course that makes options accessible to anyone.
It's a neat demo of vibe coding: reviving dead documents and reshaping old content into a new product form without rewriting from scratch.
