A day counts once it has settled: once the posts still expected for it are below the threshold, or, for posts loaded afterwards from an archive, once they’re loaded. Coverage day by day is in this reading’s conditions. How coverage is recorded.
This reading was made with methods that are still being validated. Every figure says which state it’s in.

Claude Cowork in each platform’s table
Where Claude Cowork sits among every ranked subject on each platform. The heavy mark is Claude Cowork; every thin mark is another subject.
#17 of 42 on Reddit219 people · Claude 8,811 (#1)
42 ranked subjects, each a tick on Reddit’s own people scale, 0 to 8,811. 43 more subjects aren’t ranked: their people figures are hidden (n 0–19 people, below the threshold of 20), so they aren’t drawn.
#16 of 21 on Bluesky30 people · Claude 895 (#1)
21 ranked subjects, each a tick on Bluesky’s own people scale, 0 to 895. 64 more subjects aren’t ranked: their people figures are hidden (n 0–19 people, below the threshold of 20), so they aren’t drawn.
Not ranked on YouTube: n 1 people, below the threshold of 20 people. Not ranked on Hacker News: n 2 people, below the threshold of 20 people.
Distinct people who posted about each subject on each platform, 14–20 Sep 2026, as of 2 Oct 2026 04:00Z, from release 2026-W38’s summary table (published; every figure coverage-limited). Each strip is on its own scale and nothing is added across platforms: one person can post on several. arXiv, Google News and Exa carry articles, which have no authors, so they have no ranking by people.

In development. In development. What: Claude Cowork’s attention and place in 2026-W38, from subject links made by rule run 10. Why: the method is still being validated. Link precision, checked by run 11 per method, not per subject: alias links 93.3% (56 of 60 judged), context links 98.3% (59 of 60 judged); on Reddit, 19% of this subject’s posts were linked by alias. Filtering: posts not about AI, and spam, bot and incentive posts, are excluded, as labelled by an open model in relevance run 8 (relevance-v1; it agrees with a stronger model on 92.1% of 3,000 W38 posts) and run 9 (non_discourse-v1; κ 0.648 against a stronger model on 600 W38 posts). What’s missing: frames and register arrive with build 4; 2 posts on Reddit matched an ambiguous name and await the model decision, so they aren’t counted. When the label goes: when frames and register are measured and the thresholds are set before launch. The agreement is model-to-model.

Posts published 14–20 Sep 2026, as of 24 Sep 2026 21:27:07Z; in development. People count distinct platform identities and are never added across platforms. Share is Claude Cowork’s posts over all posts AIDRAN captured on that platform in the window. Reddit’s posts include its comments. There’s no normal share to compare with yet: a baseline needs earlier weeks of this subject. Choose any number to see what it rests on and the posts behind it.

Posts about Claude Cowork by community, 14–20 Sep 2026, as of 24 Sep 2026 21:27:07Z; in development. Each platform is drawn on its own scale. The word after each community is its type: who is there, not what it’s about (users are people who use one AI product; builders build with AI). A post counts once, in the community it was posted in.

Change
Change isn’t read against the week before (2026-W37) yet: this reading was made before that week’s readings were stored.
Change compares this reading with the previous stored reading of the same subject, usually last week’s, and both endpoints stay visible with their dates. Each value carries its n; open it for its full conditions, coverage included. Stored weeks, above, cross eras, which marks a change in how weeks were captured: March era weeks were rebuilt from archives, with live capture from 7 Mar to 31 May, Archive backfill weeks were backfilled from archives (Reddit, Hacker News and arXiv only) and September era weeks were captured live from 16 Sep and filled in from archives.
