Simon Willison builds a new blog feature using Codex voice mode
What happened
On 9 October 2026, Simon Willison wrote that he used the voice conversation mode in the Codex tab of the ChatGPT desktop app to have GPT-6 Astra High build a Newsletters page for his personal blog during half an hour of cooking. The feature includes a new Django model, four import scripts, a /newsletters/ archive page and integration with the site search. The report does not mention whether there had been any earlier development plans or progress, and the publicly available information covers only this one voice-mode development process and its output.

- Simon WillisonA new feature for my blog, built using my voice
I shipped a new feature for my blog today: the Newsletters page, which offers an index of all of the newsletters I've sent out, both my free weekly Substack and my monthly sponsors-only updates. I built the feature almost entirely using my voice, chatting away to my laptop while I cooked dinner.
