Changelog

Each dated note is either a vendor page we can link, or a change on this site. There are no visitor counts, index rankings, or other traffic figures.

2026-10-21 — Claude Duet research preview

Anthropic's introducing article is dated 2026-10-21. It says a research preview is available by waitlist, starting with Pro and Max subscribers in the US.

The support article is the longer access note: US only during the preview, invitations in waves, Team and Enterprise not included yet, and one limit reset available until November 30, 2026. The product page describes the same US Pro and Max waitlist.

2026-10-23 — Guides on this site

English and Chinese versions of six guides went up together: what Duet is, access and the waitlist, availability outside the US, a comparison with Muse and Dots, this changelog, and the unofficial notice. A claim on those pages links to the vendor page it came from.

2026-10-23 — Recipe index

The recipe index is read from JSON when the site is built. This build includes 10 active recipes. That number is the count of those files, not a measure of how often anyone uses them. The current snapshot summarizes official Duet examples and links each one to its source. Prompt text is not included. The list is on the index.

2026-10-23 — Feed

This build also writes /feed.json, /rss.xml, and /zh/rss.xml. Each entry is a recipe summary and a link. Prompt text is not included.
