About Tech & AI Substack communities
What are the most active Tech & AI Substack groups this week?
1. She Writes AI Community (49/100); 2. Standout Systems by Teodora (47/100); 3. Product with Attitude (26/100). These positions use the current seven-day activity index through Oct 22, 2026 UTC and can change when a new qualified day is added.
How large is Subshack's Tech & AI groups index?
This page contains 213 observed Tech & AI communities inside Subshack's index of 1,867 public Substack groups. The category covers technology, artificial intelligence, software, coding, data, and automation. Metrics use a rolling seven-day window through Oct 22, 2026 UTC.
What is the current activity rate for Tech & AI communities?
16 of 213 observed groups currently qualify for ranking, an activity rate of 8%. Here, activity rate means the share of observed groups with at least one complete UTC day confirmed by three independent Subshack installations during the seven-day window.
How responsive are Tech & AI Substack groups?
Ranked Tech & AI groups recorded 12 aggregate messages in the current window. Their mean published reply rate is 12 replies per thread, calculated from the 16 ranked communities; it is a conversation signal, not a guarantee that any individual post will receive a response.
How does Subshack calculate the seven-day activity score?
Each complete UTC day combines aggregate messages, active participants, replies, and help requests into a score from 0 to 100. A day counts only after three independent Subshack installations report it. The leaderboard uses the mean of qualified days in the latest seven-day window; raw messages and member identities are never stored in the public index.
