POST POST-MORTEM

Why Did This Post Fail?

"Your AI post-mortem for every failed post."

Upload a post that didn't perform — the image, the caption, and (optionally) a screenshot or export of its basic analytics — and the AI digs into why it fell flat, instead of just handing you another generic headline. You get: This is much more useful than simply asking an AI to "generate me a viral caption" — it diagnoses your actual post first, then fixes the specific thing that's holding it back.
About "Analyze Post": this uses Google AI (Gemini) to look at your image, caption, and analytics together and write the scorecard, diagnosis, and refined version below. If the AI connection is ever unavailable, it automatically falls back to a lightweight built-in analyzer instead — either way, treat the scores and suggestions as a strong starting point, not gospel.

A screenshot of your post's Insights/Analytics panel (reach, impressions, likes, comments, shares, retention) works best — a plain .txt or .csv export also works.

👉 Step‑by‑Step Guide

01
Upload the Post Image (Mandatory)*
Use the exact image or thumbnail you posted — not a redesigned version.
02
Enter the Post Caption (Mandatory)*
Paste the caption exactly as it was published, including any emojis or hashtags.
03
Add Basic Analytics (Optional)
A screenshot of reach, impressions, likes, comments and shares lets the AI tell "nobody saw it" apart from "people saw it and scrolled past," which changes the diagnosis.
04
Click "Analyze Post"
The AI scores the post across five factors and names the single biggest problem — not a generic checklist.
05
Review "Try This Version"
A refined hook, caption, and image prompt built specifically to fix what the diagnosis flagged.
06
Click "Open in Image Post Generator"
Carries the refined hook straight into the Home page so you can rebuild the post with it.
