Codex Live Demo: Building a Translation Extension
gabrielchua · x · 2026-07-12
During a live stream, the author and @youtubejocoding conducted a hands-on demo centered around Codex. The core demos consisted of two parts: - Using Codex to build a simple Chrome extension in under 15 minutes for translating YouTube Live comments in real-time - Spontaneously enabling ChatGPT Voice for the entire one-hour stream to perform real-time Korean ↔ English interpretation, which worked surprisingly well The focus of the post isn't product promotion, but rather demonstrating the practical viability of coding agents in rapid prototyping and facilitating communication on the fly.
