Simon Willison reported shipping a new Newsletters page for his personal blog, acting as an index for both free weekly Substack editions and monthly sponsors-only updates. According to the disclosure, the feature was constructed almost entirely through spoken conversation with a laptop while cooking dinner.
Development Using Voice Mode
The implementation relied on the ChatGPT desktop app utilizing the Codex tab and its voice conversation mode. The development session connected directly to a local development environment running against a local blog checkout. The announcement did not specify the exact underlying model version powering the Codex voice mode, nor did it detail the specific prompts or conversational steps required to generate the final code.
Unknown Implementation Details
Many technical specifics regarding the build process remain undisclosed. The announcement did not specify how many iterations the voice session required, whether any manual code adjustments were necessary after the voice generation completed, or how long the total development process took from start to deployment. What to watch next is whether similar voice-driven workflows become more common for rapid feature prototyping among developers.
The new index is currently live on the blog.
