8 Notes - 4 FormatsEducational, Growth, Entertaining, Inspirational (2 each)

I write on Substack about [YOUR NICHE/TOPIC]. Write me 8 Substack Notes: 2 educational (teach something specific), 2 growth-focused (about building an audience or business), 2 entertaining (a specific personal story or observation), and 2 inspirational (a mindset shift, no generic quotes). Each Note should be under 150 words, start with a specific detail or number (not a question), and end with something that invites a reply. Here's a recent post of mine for context and voice: [PASTE A RECENT POST OR NOTE]

Awareness LadderOne Note per audience awareness level - from cold to ready-to-act

I write on Substack about [YOUR NICHE/TOPIC]. Write me 5 Substack Notes, one for each stage of awareness: (1) someone who doesn't know they have this problem, (2) someone who knows the problem but not the solution, (3) someone comparing solutions, (4) someone who knows my specific approach but hasn't tried it, (5) someone ready to act. Each Note should match that reader's mindset exactly - don't sell to a cold reader and don't over-explain to a ready one.

Respin Your Best Note5 variations of your top-performing Note - different angles, same insight

Here's my best-performing Substack Note: [PASTE YOUR TOP NOTE]. Write 5 variations of this same core insight, each from a different angle - a personal story version, a contrarian take, a numbered-list version, a question-first version, and a mistake-I-made version. Keep the core insight identical; only change the framing and opening line.

Article to 10 NotesTurn a long post into 10 standalone Notes

Here's a full post I wrote: [PASTE YOUR ARTICLE]. Extract 10 standalone Substack Notes from it - each one should be a complete, specific idea that works on its own without needing the rest of the article for context. Don't just quote sentences; pull out the single sharpest point from each section and rewrite it as its own short, punchy Note.

Hook RewriterRewrite your opening line using proven hook formulas

Here's the opening line of a Substack Note I'm drafting: [PASTE YOUR OPENING LINE]. Rewrite it 8 different ways using these hook formulas: a specific number, a contrarian statement, a confession/mistake, a direct question, a 'most people think X but' structure, a mid-story cold open, a before/after contrast, and a blunt one-line claim. Keep each version under 15 words.

10 Discussion StartersNotes engineered for comments (which boost reach)

I write on Substack about [YOUR NICHE/TOPIC]. Write 10 Substack Notes specifically designed to get replies, not just likes - each one should end with a genuine, specific question (not 'thoughts?') that a reader could actually answer from their own experience in one sentence.

21 Angles from 1 IdeaTurn one topic into 21 different Notes using proven angle types

Here's one idea or insight I have: [PASTE YOUR IDEA]. Give me 21 different Substack Notes built from this single idea, each using a different angle: a personal failure, a reader example, a contrarian take, a step-by-step breakdown, a myth-busting frame, a before/after, a question to the audience, a prediction, a comparison to something unrelated, a confession, a list, a single statistic, a quote reaction, a 'here's what nobody tells you' frame, a mini case study, a warning, a definition reframe, a timeline, a cost/benefit frame, an 'if I started over' frame, and a blunt opinion.

Analyze Why This Note WorkedAI compares your best vs worst Note and tells you why

Here are two of my Substack Notes - one that performed well and one that didn't. BEST: [PASTE YOUR BEST NOTE, with like/restack/comment counts if you have them]. WORST: [PASTE YOUR WORST NOTE, with counts]. Compare them and tell me specifically what structural, topical, or stylistic differences likely explain the gap - not generic advice, but what's actually different between these two specific Notes.

Pacing

A pace, not a post dump.

Queuing a week of Notes at once is efficient - publishing all of them in a burst isn't. Spread them out so each one gets a fair shot at your audience instead of competing with itself.

5

recommended max / day

A real 30-day experiment found more than 3-5 Notes a day shows diminishing returns - this is a guideline from that research, not a platform-enforced limit.

Why does posting less outperform more?

Notes compete for the same slice of your audience's attention - posting far more than a handful a day tends to split engagement across your own Notes rather than growing it. See the full research.

Your Notes stay on your device

NotesIQ reads your Notes through your existing Substack session and keeps them, your profile, and your subscriber stats in your browser - always. AI generation and license checks are the one disclosed exception: they call our relay to work at all. We list exactly what it sends, and why.

FAQ

Questions?

Talk to us
What is NotesIQ?

NotesIQ is a Chrome extension built specifically for Substack Notes analytics, draft scheduling, and AI-assisted writing - all running inside your browser.

Can I schedule Substack Notes?

Yes. Draft a single Note or load up a whole week's worth in the Queue, and NotesIQ will publish them for you at the scheduled time.

What is the best time to post Substack Notes?

It depends on your own audience, not a generic rule - NotesIQ's Best Time Heatmap maps your engagement across a 7-day x 6-time-slot grid so you can see exactly when your Notes do best.

How do I track engagement on my Substack Notes?

NotesIQ automatically tracks likes, restacks, comments, and content type for every Note you post, plus an all-time trend view - Substack's own dashboard only shows the last 90 days.

Can I analyze a competitor's Substack Notes?

Yes. Look up any public Substack handle in the Competitor tab to see their content mix, posting patterns, and best times.

Why aren't my Substack Notes getting engagement?

Usually it's timing or content type. The Content Type Breakdown and Best Time Heatmap show exactly which kind of Note and which time slot underperforms for your specific audience, so you can adjust instead of guessing.

How much does NotesIQ cost?

The core analytics and scheduler are a one-time Lifetime payment ($19). AI features (Ghostwriter, Post Coach) are a separate subscription add-on at $9/mo.
