Colophon
How the paper is made.
The 221B Daily is built with Astro and Tailwind, served from Cloudflare Workers, and backed by Cloudflare D1 for reader sessions, verdicts, archive access, and share passes.
Daily cases are written with generative AI and checked by a separate verifier before publication. Audio editions are rendered with Kokoro TTS. Illustrations are generated in a Paget-inspired black-and-white newspaper style and reviewed before they are assigned to cases.
The paper is an independent fan work using the public-domain Holmes canon published before 1928. It is not affiliated with the Conan Doyle Estate or any Holmes publisher or society.
