NotesIQ - Substack Notes Analytics & Scheduler

Analytics, scheduling, and AI drafting for Substack Notes - right in your browser, no account required.

NotesIQ is an analytics and scheduling tool for Substack Notes, built entirely into your browser's side panel. No account, no sign-up, no data leaves your device except when you explicitly use an AI feature. Track your own Notes • Notes tracked, day streak, total likes/restacks/comments, and your top-performing Notes • Content Type Breakdown: see which kind of Note (Personal Story, Question, List/Tips, Quote/Repost) gets the most engagement • Best Time Heatmap: a 7-day x 6-time-slot map of when your Notes do best • Trend Analytics: weekly volume and daily engagement charts, with an All-Time view going back to your very first tracked Note (Substack's own dashboard only shows 90 days) • Viral Alert: a banner the moment a Note is doing meaningfully better than your own average • Evergreen Recycler: surfaces old Notes (60+ days) that did well, one click to reuse them • Subscriber Growth: auto-detects your subscriber count from your public profile and tracks it over time Community feed • Aggregate analytics across every Note you've scrolled past on Substack, not just your own Compose and schedule • Post or schedule a single Note through Substack's own native composer and scheduler • Queue tab: load up a whole week's worth of Notes at once, with one-click best-time autofill Competitor research • Look up any public Substack handle to see their content mix, posting patterns, and best times Top Fans • A leaderboard of who restacks and comments on your Notes the most Bookmarks • Save any Note (yours, a competitor's, from your feed) for later reuse Prompt Templates • 8 copy-paste prompts for ChatGPT or Claude, some pre-filled with your own top Notes AI Coach (requires AI Pro add-on) • Ghostwriter: drafts a new Note in your own voice, based on your best-performing Notes • AI Post Coach: one concrete, data-grounded suggestion for what to write next Backup and export • Full backup/restore as a JSON file, CSV export, and a Media Kit export for sponsor pitches Pricing A one-time $29 Lifetime payment unlocks everything except AI Coach. AI Coach requires a separate $9/month AI Pro subscription, since AI drafting has a real per-generation cost. Both are backed by a 7-day money-back guarantee.
