How humanity talks about AI
AIDRAN publishes a numbered release every week: readings of what people say about AI, platform by platform, with the conditions behind every figure and the posts behind every number.
A reading measures one subject over one week. Release 2026-W40 was published 8 Oct 2026, and its figures never change.
What 2026-W40 found
The top three subjects on Reddit, each told a different way from its reading’s stored figures. Each reading page keeps its measured statements word for word. Each figure says which state it’s in.

Posts published each day of 28 Sep – 4 Oct 2026 on each platform, drawn on that platform’s own scale: the bars show the shape of each platform’s week, never one platform against another. As of 8 Oct 2026. People count distinct platform identities and are never added across platforms.
The summary table, platform by platform
The top 5 on each platform with a ranking in 2026-W40. Claude leads on Reddit and Bluesky; ChatGPT leads on YouTube. Each platform has its own ranking.
Distinct people who posted about each subject, 28 Sep – 4 Oct 2026, as of 8 Oct 2026. Each bar is scaled to its own platform’s first place, and nothing is added across platforms, because one person can post on several. A hidden figure shows its reason, never a number. arXiv and Exa carry articles, which have no authors, so they have no ranking by people.

Posts about each subject in its five largest Reddit communities, 28 Sep – 4 Oct 2026, as of 8 Oct 2026. Each subject is drawn on its own scale. The word after each community is its type: who is there, not what it’s about. A post counts once, in the community it was posted in.

Conditions beside every number
Each figure shows the posts it counts, the coverage behind it and its n. Never in a footnote.
The posts behind every number
Any figure opens a fixed sample of up to 10 posts, each linked to the original.
Published readings never change
A revision or correction is a new reading. The old one stays online, with a dated notice.
No one is profiled
Authors are never shown. People are counted, never named, and never linked across platforms.
