Analyze a different subredditBased on 100 top posts from the past year. Times in UTC.
Note: Reddit timestamps are UTC. Subtract or add your offset to convert (EST = UTC-5, PST = UTC-8). Top posts are weighted by total upvotes.
r/ChatGPT has massive consistent activity across all time zones — there is no real off-peak. Notable spikes coincide with OpenAI announcements, model releases, and viral use-case discoveries. The audience is enormous and diverse, ranging from technical AI researchers to casual curiosity browsers. Posting during major news events about AI can either gain huge visibility or get drowned depending on the angle. Outside of news events, the activity volume means almost any window works.
Times above are UTC — the heatmap reflects the trailing 12 months of top posts, so it captures long-term patterns rather than this week's activity. Have questions about how this works? See the main tool page for FAQs.
