# NotesIQ

> Substack Notes analytics and scheduling, built into a Chrome extension. Reads your Notes through your existing, already-logged-in Substack session and turns them into a real analytics dashboard - no separate account, no API keys.

Key facts:
- One-time $19 payment for Lifetime access to the full analytics dashboard and scheduler - no subscription for the core product.
- Optional AI Pro add-on at $9/mo unlocks Ghostwriter (AI drafting in your own voice) and AI Post Coach.
- No account or sign-up: NotesIQ reads your Notes through your existing Substack session in the browser.
- Notes, profile, and stats are stored on-device by default (browser IndexedDB). The only disclosed exception is AI drafting and license checks, which call NotesIQ's own relay server.
- Chrome extension (also works on Chromium browsers like Edge and Brave). Not affiliated with Substack.
- 7-day money-back guarantee on the Lifetime purchase.
