What it does

Send it anything:

• A script or raw notes
• A screenshot or image of your post
• A competitor's viral post (it'll write something better)
• A brief description of your content
• A link to an article you're repurposing

You get back **ready-to-copy captions for 7 formats**, each using a different proven formula:

1. Instagram Reels — hook-first, optimized for DM shares
2. Instagram Carousel — longer, save-optimized
3. TikTok — 80-char hook, completion-rate language
4. Threads — conversation starter, reply-optimized
5. Facebook Page/Personal — trigger-word-free for max reach
6. Facebook Group — community tone, discussion question
7. YouTube Shorts — title + description, search-keyword-optimized

Each caption comes with a breakdown: formula name, hook type, CTA type, and which algorithm signal it optimizes for.

Why every platform needs a different caption

Most creators copy-paste the same caption to every platform. That's why their reach dies on 6 of the 7.

Every algorithm rewards different signals in 2026:

Platform	#1 signal	Dead signal
Instagram Reels	DM shares	Likes
Instagram Carousel	Saves	Likes
TikTok	Completion rate (70%+)	Hashtag spam
Threads	Replies	Cross-posted content
Facebook Page	40-80 char posts	Trigger word
