What this release found
The first place on each of the two platforms that count people, in its reading’s own words. Two platforms, two rankings; nothing here is added across them.
On Reddit, 7,139 distinct people posted about ChatGPT between 19 and 25 January 2026: 9,369 posts, an estimated 3.71% of that week's Reddit posts about AI, leaving out templated automated posts (99.8% of these posts had an identifiable author).

On Hacker News, 33 distinct people posted about Claude between 19 and 25 January 2026: 33 posts, 12.60% of that week's Hacker News posts about AI (100.0% of these posts had an identifiable author).

Each card is the lead measured statement of one platform’s first place: the stored statement whose figures include that platform’s people count, shown verbatim. Platforms rank separately.
The summary table
Every subject’s place on each platform that counts people, side by side. Read down a column for one platform’s ranking; read across a row to see how differently the platforms rank one subject.
People per subject on each platform, 19–25 Jan 2026: the first 15 in Reddit’s order
Distinct people who posted about each subject, 19–25 Jan 2026, as of 25 Sep 2026 19:30Z; published. Each column is scaled to its own #1 and ranks on its own; nothing is added across platforms, because one person can post on several. Rows follow Reddit, the default platform. Hatched cells are hidden, never shown as a number. The stored reason, e.g. Hacker News ChatGPT: “n 9 people, below the threshold of 20 people”. Each column’s n 252,246 posts on Reddit and 262 on Hacker News.
Posts, no peoplearXiv, Google News and Exa are not ranked. Article sources have no authors, so people aren’t counted. Posts per subject, largest first:
arXiv n 338 posts · 85 subjects
GPT 10, Gemini 9, Qwen 6, Llama 4 posts, and 81 more subjects
Google News n not recorded · 85 subjects
Not counted this week: Google News has no day between 19 and 25 January 2026 that AIDRAN counts, so there’s no figure to show.
Exa n not recorded · 85 subjects
Not counted this week: Exa has no day between 19 and 25 January 2026 that AIDRAN counts, so there’s no figure to show.
The week after
The same subjects one week later, on the platform with enough people. GPT grew on Reddit while Claude Code eased.
Reddit · people per subject
2026-W04 19–25 Jan 2026 n 252,246 posts
2026-W05 26 Jan – 1 Feb 2026 n 256,684 posts
Distinct people per subject on each release’s board, for subjects with n ≥ 100 posts in both weeks (30 on Reddit), as of 25 Sep 2026 19:30Z; published. Each panel on its own scale; lines join one subject’s two weeks. Each week’s n is its platform’s posts: Reddit n 252,246 and 256,684 posts. 2026-W04 and 2026-W05 follow on from each other, so their lines are joined.

What the fills and flags meanactive, episodic, not started, no lane; partial, low capture, late heavy; settled
Active. AIDRAN was collecting that day.
Episodic. Collected in batches, not continuously.
Not started. Collection hadn’t begun; posts published that day were captured later and do count.
No lane. Collection had stopped.
flag
Partial, low capture, late heavy. A day captured only in part, captured thinly, or whose posts mostly arrived late. On a phone a bar marks a flagged day.
settled
Settled. Every day that can settle has settled; the rest say not applicable. How settling works
Coverage computed 2 Oct 2026 03:23Z · as of 25 Sep 2026 19:30Z · frozen with the release, never recomputed. Each day opens what it holds.A bar marks a flagged day.
