Planning & Scripting Tools

Eight tools that turn the most-asked short-video planning questions into numbers and pictures. Use them while you draft; none of them require a finished video.

Hook Pattern Classifier

Classify your hook (the first 1-3 seconds) by psychological pattern. Most viral short hooks match one of 8 patterns; this tool scores your draft against each.

How to read the score

Each pattern gets 0–10. The top pattern is your primary hook style. Two scores above 6 mean you are stacking patterns (good); three above 6 starts to feel manipulative to viewers (bad for retention).

Use this before writing the body. If no pattern scores above 5, your hook is informational, which works only for specific niches (tutorials, news). For storytelling, transformation or curiosity content, you want at least one pattern above 7.

Original notes & limits

This is a pattern matcher, not an AI judge of truth. A "social proof" hook that fabricates numbers will get a high score - your ethics are still on you. The 8 patterns we use come from a survey of publicly analyzed top-performers, not platform-secret data.

The English-language heuristics may mis-rank very short hooks (under 6 words). Add a few more words if your top score feels wrong.

Cross-Platform Caption Diff

Paste a caption. See which platform cuts it off, where, and how many characters of context you lose.

How to interpret results

Each platform uses different cut-points where the text is collapsed with "...see more". The truncated tail is where hooks, hashtags and CTAs die. Lead your real value inside the first cutoff.

The Fog Index is a measure of how many characters of your message survive on every platform. Above 80% = one caption works for all. Below 50% = you need platform-specific versions.

FAQ

Q: Do character counts include spaces and emojis? Yes, we count code points - which matches how the platforms display. Emojis can be 2 code points.

Q: Are these limits exact? They reflect currently documented platform guidance. Platforms occasionally change their collapse thresholds.

Q: My hashtag shows as cut - shouldn't hashtags be after the fold? Exactly. Hashtags below the fold don't contribute to search ranking. Pull them up by trimming filler.

Hook Word Count Optimizer

How many words can viewers actually comprehend in 1.5 / 3 / 5 second hooks? Find the ceiling for your delivery speed.

How to interpret

Coverage > 100% means viewers can't comfortably process the words in that time. Human comfortable WPM while listening is around 150-180; comprehension drops sharply above 200 wpm.

Script Length → Runtime

Estimate how long a written script runs when spoken, including pause and cut time.

B-roll / cutaway count. Each cut ≈ 0.4 s of music/sfx time.
Notes & limits

Estimate assumes pure prose. Songs, repeated emphasis, "uh/uhm" filler, and dramatic pauses will stretch runtime 10–25% longer than the math says. Re-test with a 30-second timer.

Title Length Optimizer

How your title gets truncated, with safe-length recommendations per platform.

How to interpret

For Shorts, aim under 60 characters so the title is fully visible on mobile. For Reels and TikTok feed, the truncation line is much shorter than the search page. Truncation shown is conservative and can collapse slightly later in real apps.

Color Palette → Emotion Mapper

Pick 2-4 dominant colors. Get a mapped emotional profile based on hue and saturation, with mood use-case suggestions.

Notes

Emotion mapping is based on documented color-psychology research (warm colors → high arousal, dark → premium, low-saturation → calm). It is a starting bias, not a rule. Cultural reading differs.

Niche-Fit Hashtag Scorer

Score hashtags on three signals: specificity (niche-fit), saturation (competition), and length. Avoid the "all-broad" trap.

How to interpret

A healthy mix is 1 broad (top of the niche), 2 mid, 1 hyper-niche (≤ 50k posts). This tool can't see live post counts, but it scores what it can observe from your tags: length, redundancy, and overlap with the niche you stated.

Cross-Platform Repurposing Plan

Enter one source caption + hook. Get a reposting checklist per platform with the edits that actually matter.

Limits

We provide structure, not "AI captions". You still need to verify each post against your own brand voice. Watermark / rebrand rules differ per platform.
