# Cross Platform Adapter

> Adapts ONE core idea into each platform's native format instead of cross-posting the same clip everywhere. It maps length, aspect ratio, tone, hook style, caption and hashtag norms, and what actually converts per platform, then outputs a per-platform adaptation table. Use when the user says "repurpose this," "cross-post," "adapt this for LinkedIn/TikTok," or plans a multi-platform push. Works wit…

# Cross-Platform Adapter

Identical cross-posting loses on every platform because each ranks and rewards different behavior. The winning move is "same idea, native execution": lock ONE core insight (the thing worth saying) and re-package everything around it — length, framing, tone, hook, and caption — to the norms of each surface. Keep the insight and the proof; change the container. A repurpose is a translation, not a copy-paste.

## 1. Extract the transferable core
1. State the ONE insight in a single sentence a stranger could repeat.
2. Identify the proof (demo, number, before/after, story beat) — this travels unchanged.
3. Write 3 hook angles: contrarian, result-first, and question. You will assign different angles to different platforms.

## 2. Adapt by platform norms
1. YouTube long: 6-12 min, teach-then-payoff, 16:9. Hook in first 15s naming the payoff; retention lives on chapters and open loops. Convert via watch-time + a clear CTA card.
2. YouTube Shorts / TikTok: 15-45s, 9:16, fast verbal hook (0-2s), on-screen captions always. TikTok rewards native/lo-fi + trending audio; add a loop or "wait for it." Convert via completion + shares.
3. Instagram Reels: 7-30s, 9:16, high-polish, strong first frame + cover text. Carousels (1080x1350) win for how-to; slide 1 is the hook, last slide is the CTA. Convert via saves + shares.
4. X: text-first, 1-3 sentences, punchy claim; thread only if the proof needs steps. Native video 1:1 or 9:16, no external links in the main post. Convert via replies + reposts.
5. LinkedIn: 150-300 word text post, line breaks every 1-2 sentences, professional but personal; lead with a result or lesson. Convert via comments; ask one question at the end.
6. Threads: conversational, lowercase-casual, 1-2 sentences, reply-bait. Convert via replies; no hashtag stuffing.

## 3. Tune hashtags, captions, and CTA
1. Hashtags: TikTok 3-5 niche, IG 3-8 mixed reach, LinkedIn 3 topical, X 0-2, YouTube in description not title, Threads 1.
2. Caption first line is a second hook — never waste it on "check out my new video."
3. One CTA per post, matched to the platform's convert metric (save/share/comment/watch).

CORE IDEA: 
PROOF: 

| Platform        | Length/Format | Aspect | Hook angle        | Caption first line        | Hashtags        | Convert lever   |
|-----------------|---------------|--------|-------------------|---------------------------|-----------------|-----------------|
| YouTube long    | 6-12 min      | 16:9   | Result-first      |                     | in description  | Watch-time + CTA|
| Shorts/TikTok   | 15-45s        | 9:16   | Contrarian        |                     | 3-5 niche       | Completion+share|
| IG Reel         | 7-30s         | 9:16   | Question          |                     | 3-8 mixed       | Saves + shares  |
| IG Carousel     | 6-10 slides   | 4:5    | Result-first      | slide 1 text              | 3-8 mixed       | Saves           |
| X               | 1-3 sentences | 1:1    | Contrarian        |                    | 0-2             | Replies+reposts |
| LinkedIn        | 150-300 words | 4:5    | Lesson/story      |                     | 3 topical       | Comments        |
| Threads         | 1-2 sentences | 9:16   | Question          |                     | 1               | Replies         |
```

## Platform variants
Vertical-native (TikTok/Reels/Shorts/Threads) share 9:16 assets but differ in polish: TikTok lo-fi, Reels polished, Shorts payoff-driven. Horizontal (YouTube long) needs its own edit, never a stretched vertical. Text-native (X/LinkedIn) may not need video at all — the insight as words can outperform.

## Rules
- Never post the same caption and hashtags across two platforms.
- Reshoot or re-crop the hook per platform; the first 2 seconds are platform-specific.
- One idea per repurpose batch — do not merge three insights to "save effort."
- Match aspect ratio natively; letterboxed or watermarked (TikTok logo on Reels) reposts get suppressed.
- Pick each platform's convert metric first, then write to it.
- If an idea has no native fit for a platform, skip that platform — do not force it.
