What is the Substack Profile & Reply Analyzer?
A browser-based research tool that collects Notes, Posts and Replies through batch-based scrolling, then organizes available text, dates, and public engagement metrics in a shared analytics dashboard. Personal and brand profiles use the same workflow. Collection and charts are free; AI strategy analysis follows your account plan.
Three clear steps from source to useful output.
Nothing is hidden behind a vague “AI magic” claim. You choose the source, inspect what was collected, and review what you create.
- 1
Open a profile
Install the extension, sign in to Creator Insights, and visit a Substack profile you want to study.
- 2
Choose activity and depth
Select feeds and a limit of 50, 100, 150, 200 or 350 items per feed. The default is 150. Keep the tab open while it loads and collects batches; Stop & View keeps partial results.
- 3
Compare posts and replies
Inspect original posts and replies separately. Read conversation context, compare visible metrics, and use your existing AI access to ask questions about the collected activity.
