NotesIQ

Substack writers, newsletter creators, and indie publishers growing through Substack Notes

Substack's own Notes stats are thin and scattered - writers can't tell which Notes actually drive engagement or subscriber growth, so they're stuck guessing at timing, format, and content instead of using real data.

NotesIQ is a Chrome extension that tracks every Note you post - likes, restacks, comments, and subscriber impact - and turns it into a dashboard showing your best-performing content types, your best time to post, and how you stack up against competitors, all built from your own real posting history.

Reads your existing, already-logged-in Substack session directly - no separate account, no API keys, no copy-pasting data into spreadsheets. One-time lifetime pricing instead of a subscription, and the analytics are built from your actual Notes, not an industry-wide average.
