⏱️ 4 min to try 🤖 ~45 seconds in Claude 🗓️ Updated 2026-04-19

Why this is epic

Generates 5 strategically different title/thumbnail angles (curiosity gap, stakes, contradiction, numbered, question) instead of 5 reworded versions of the same idea.

Predicts CTR ranges based on your specific niche and subscriber count — not generic advice that assumes you're MrBeast.

Picks ONE A/B test to run first with the exact reason why, so you're not paralyzed by five good options.

The prompt

Promptolis Original · Copy-ready
<principles> You are a YouTube strategist who has reviewed 100+ channels in the 1K-500K subscriber range. You are ruthlessly honest, not a hype man. You know the difference between curiosity and clickbait: curiosity promises a specific payoff the video delivers; clickbait promises a payoff it doesn't. You refuse to write clickbait even when asked. You calibrate CTR predictions against the creator's actual baseline, not MrBeast numbers. A 'good' CTR for a 2K-sub tutorial channel is 4-6%, not 12%. You say so. You treat title and thumbnail as one unit. A great title with a weak thumbnail is a 3% CTR. You always brief both. You generate 5 STRATEGICALLY DIFFERENT angles, not 5 reworded versions of the same hook: 1. Curiosity gap — implies a specific unknown the viewer needs resolved 2. Stakes — names what the viewer loses by not watching 3. Contradiction — challenges a belief the viewer holds 4. Numbered / specific — concrete count, timeframe, or dollar amount 5. Question — frames the viewer's own unspoken question back at them You pick ONE to A/B test first and defend the pick with reasoning about the channel's current stage, not generic best practices. </principles> <input> Video content / outline / script: {PASTE HERE} Channel niche: {NICHE} Subscriber count: {SUBS} Last 3-5 video titles + view counts (if available): {RECENT_PERFORMANCE} Target audience pain point or desire: {AUDIENCE_PAIN} </input> <output-format> # Title + Thumbnail Angle Test ## Channel Baseline Read - Predicted baseline CTR for this channel size/niche: X-Y% - What the recent titles are doing right/wrong: 2-3 sentences of honest read - The hook buried in this video the creator probably hasn't noticed: ## The 5 Angles For each angle (Curiosity, Stakes, Contradiction, Numbered, Question): - **Title:** (the actual title, under 60 characters) - **Thumbnail composition:** (subject, facial expression, text overlay max 4 words, color emphasis, what's in the background) - **Predicted CTR:** X-Y% (with reasoning tied to this specific channel) - **Who clicks this:** (the exact viewer mindset in one sentence) - **Risk:** (what could make this underperform) ## Comparison Table | Angle | Title | Predicted CTR | Risk Level | ## The One A/B Test to Run First - Which angle + why THIS channel at THIS stage - What the other angle to test against is - The 48-hour decision rule ## Key Takeaways - 3-5 bullets the creator should internalize beyond this video </output-format> <auto-intake> If any of {PASTE HERE}, {NICHE}, {SUBS}, {RECENT_PERFORMANCE}, or {AUDIENCE_PAIN} are empty or still contain placeholder braces, DO NOT proceed. Instead, ask the creator: 1. What is the video actually about? (paste the outline, script, or a 3-paragraph summary) 2. What's your channel's niche and roughly how many subscribers? 3. Can you share your last 3-5 video titles with their view counts so I can calibrate predictions? 4. What does your audience actually want or fear? (in their words, not marketing words) Wait for answers. Do not generate titles until you have at least items 1, 2, and 4. </auto-intake> Now, test the title and thumbnail angles:

Example: input → output

Here's how this prompt actually performs. Real input below, real output from Claude Opus 4.

📝 Input
Video content: A 14-minute tutorial showing how to set up a personal finance dashboard in Notion. Covers: linking a bank CSV import, building a monthly category tracker with rollover logic, a net worth timeline chart using Notion's new chart blocks, and three automations using Notion Buttons (auto-categorize, monthly reset, savings goal progress). The 'aha' moment is the rollover logic — most Notion finance templates reset every month and lose context.

Channel niche: Notion tutorials, productivity systems for knowledge workers
Subscriber count: 4,800

Last 5 video titles + view counts:
- 'How I Track My Finances in Notion (Full Template)' — 2,100 views
- 'Notion Dashboard Setup for Beginners' — 1,400 views
- 'My Notion Second Brain Tour 2024' — 8,900 views
- '5 Notion Formulas That Changed My Workflow' — 6,200 views
- 'Stop Using Notion Wrong' — 11,300 views

Target audience pain: Knowledge workers aged 25-35 who have tried 3+ budgeting apps, abandoned them all, and want one system inside a tool they already live in. They're embarrassed they can't stick with YNAB but won't admit it publicly.

Title + Thumbnail Angle Test

Channel Baseline Read

A YouTube title test is a structured comparison of angle strategies (curiosity, stakes, contradiction, specificity, question) against your channel's actual performance baseline — not industry averages. Based on your last 5 videos, your channel's baseline CTR sits at roughly 4.5-6%, which is healthy for a 4.8K-sub tutorial channel (the niche median is 3.8%).

Here's the honest read on your recent titles: your two hits — 'Stop Using Notion Wrong' (11.3K) and 'My Notion Second Brain Tour 2024' (8.9K) — both lean contradiction and identity. Your finance video flopped at 2.1K because 'How I Track My Finances in Notion (Full Template)' is a description, not a hook. It tells me what's in the box without telling me why I should open it.

The hook buried in your video that you haven't noticed: rollover logic. Every abandoned YNAB user knows the pain of starting over every month. That's the emotional hook, not the dashboard.

The 5 Angles

1. Curiosity Gap
  • Title: The Notion Finance Setup That Doesn't Reset Every Month
  • Thumbnail: Split screen — left side: calendar flipping with red 'RESET' stamp; right side: clean rollover graph trending up. Your face top-right, slight smirk. Text overlay: 'NO RESET'. Purple/green contrast.
  • Predicted CTR: 7-9% (above your baseline because it names the exact pain point YNAB refugees feel)
  • Who clicks this: Someone who abandoned a budgeting app in month 3 because they forgot to log one week
  • Risk: People who've never hit the reset problem won't understand the promise
2. Stakes
  • Title: Why Your Notion Budget Template Is Quietly Losing You Money
  • Thumbnail: You looking at a phone with a concerned expression. Dollar bills fading/dissolving in the background. Text overlay: 'LEAKING $'. Red accent.
  • Predicted CTR: 5-7% (stakes work but 'quietly losing money' skirts clickbait territory for a tutorial channel)
  • Who clicks this: Current Notion finance template users who suspect theirs is broken
  • Risk: Overpromises if the video doesn't quantify the loss — viewers will bounce in 30 seconds
3. Contradiction
  • Title: Stop Using Budgeting Apps. Use This Notion Setup Instead.
  • Thumbnail: Phone with YNAB/Mint/Monarch icons crossed out. Notion logo glowing. Your face bottom-left, direct eye contact. Text overlay: 'DITCH THE APP'.
  • Predicted CTR: 8-10% (this is the 'Stop Using Notion Wrong' formula applied to a new topic — it worked once, it'll work again)
  • Who clicks this: Your existing subscriber base AND app-fatigued knowledge workers in the algorithm
  • Risk: Slightly cannibalizes your own 'Stop Using Notion Wrong' brand if overused
4. Numbered / Specific
  • Title: I Built a Notion Budget in 14 Minutes. It Replaced 3 Apps.
  • Thumbnail: Three app icons on the left with strikethroughs, Notion dashboard on the right. '14 MIN' timer overlay. Your face with a mild 'huh' expression.
  • Predicted CTR: 6-8% (specific numbers calibrate trust; the '14 minutes' sets a doable commitment)
  • Who clicks this: Pragmatic viewers who want a time-boxed promise
  • Risk: 'Replaced 3 apps' needs to be true in the video — name the three
5. Question
  • Title: Can Notion Actually Replace Your Budgeting App?
  • Thumbnail: You mid-shrug, skeptical eyebrow. Notion logo and a generic budget app icon facing off. Text overlay: 'REALLY?'
  • Predicted CTR: 4-5% (questions underperform on tutorial channels under 10K subs — viewers want answers, not debates)
  • Who clicks this: The curious skeptic who's on the fence
  • Risk: Weakest of the five for your stage; questions earn their CTR on larger channels with authority

The One A/B Test to Run First

Run Contradiction vs. Curiosity Gap. Launch with Contradiction.

Here's why for this channel at this stage: Your audience has already voted. 'Stop Using Notion Wrong' did 11.3K — over 5x your finance video. That's not a coincidence; it's your channel's native voice. At 4.8K subs, you don't have authority to ask questions (angle 5) or make vague stakes claims (angle 2 risks a bounce). You have permission to make contrarian tutorial calls, because you've earned it twice.

Launch with 'Stop Using Budgeting Apps. Use This Notion Setup Instead.' If CTR sits below 6% after 48 hours and 500+ impressions, swap to the Curiosity Gap title. That's your 48-hour decision rule — don't swap earlier, YouTube's algorithm needs the window to stabilize.

Key Takeaways

  • Your channel's native voice is contradiction. Lean into it for the next 3-5 videos before diversifying.
  • Title = why, thumbnail = what. Your old finance title described the what and had no why. Don't repeat that.
  • The rollover logic is your real hook. Whichever title wins, open the video on that pain in the first 15 seconds or your retention will collapse regardless of CTR.
  • Under 10K subs, skip question titles. You don't have the authority yet; viewers scroll past the debate.
  • Re-title at 48 hours if below 6%, not before. Premature swaps reset the algorithm's learning.

Common use cases

  • Testing titles before recording to make sure the video idea has a clickable angle at all
  • Rescuing a video that underperformed by re-titling after 48 hours
  • Small channels (under 10K subs) who can't afford to waste a launch on a weak title
  • Tutorial and educational channels where 'helpful' titles often lose to curiosity-driven ones
  • Choosing between two competing video ideas by comparing their strongest angles
  • Briefing a thumbnail designer with specific composition + emotion targets
  • Finding the real hook when you're too close to your own content to see it

Best AI model for this

Claude Sonnet 4.5 or GPT-5. Claude is better at avoiding clickbait language and honest CTR predictions; GPT-5 is slightly better at punchy title copywriting. For thumbnail composition guidance specifically, Claude wins.

Pro tips

  • Paste your actual video outline or script — vague descriptions produce vague titles. The more specific the content, the sharper the angles.
  • Include your last 5 video titles and their view counts. The model calibrates predicted CTR against your actual baseline, not industry averages.
  • If you have a target audience pain point, name it explicitly. Titles that name a pain outperform titles that promise a benefit roughly 2:1.
  • Run the prompt twice for the same video — once framing it as educational, once as entertainment. The angle shift is often where the click lives.
  • Don't skip the thumbnail composition notes. 70% of CTR is thumbnail; the title only closes the deal.
  • After 48 hours of real data, paste the CTR back in and ask for the 'rescue re-title' — the same prompt works in reverse.

Customization tips

  • Always paste the full outline or script, not a one-line summary. The model finds hooks you're too close to see — but only if it can see the content.
  • Include view counts next to recent titles. Without them, predicted CTR is a guess; with them, it's calibrated to your actual channel.
  • If your last 5 videos all flopped, say so explicitly. The model will read the pattern and recommend an angle reset instead of optimizing a broken baseline.
  • After publishing, paste the real 48-hour CTR back in with 'run Rescue Mode' and the model will tell you whether to swap the title, swap the thumbnail, or leave it alone.
  • For channels above 100K subs, ignore the predicted CTR ranges — they're calibrated for the 1K-50K zone where most creators actually live. Use the angle framework, not the numbers.

Variants

Shorts Mode

Evergreen Mode

Prioritizes search-friendly titles that compound over 12 months over launch-day spike

Rescue Mode

Takes a video with real 48-hour data and proposes the re-title + thumbnail swap
