The Caption Stack — Free AI Prompt for Writing Instagram Captions

CREATOR PROMPT VAULT · CAPTIONS & CTAS · 15

The Caption Stack

What it does: Write 3 caption options — each ending in a comment trigger that drives reach. It's the AI prompt for writing Instagram captions — free, copy-paste, and it works in Claude, ChatGPT or Gemini.

The prompt

[Paste CREATOR PROFILE]
Video topic: [topic]. Write 3 caption options:
(a) one-liner + 3 niche hashtags, (b) mini-story caption that adds context
the video didn't have, (c) value-add caption with one bonus tip.
Each ends with a comment trigger — a question or keyword prompt.

How to use it

Run prompt 01 (the Creator Profile) first and paste its output at the top of your session, then fill the [brackets] above and run this one. Works on the free tier of any major AI.

Why it works

A caption is a second hook. Giving the AI three distinct angles — and forcing a comment trigger on each — turns passive viewers into commenters, which the algorithm rewards.
