I built an AI that writes social media posts for small business owners — feedback welcome

Hey IH,

I've been building PostPMI — a tool that helps small business
owners generate social media posts without an agency or hours
of work.

THE PROBLEM
Small business owners (restaurants, artisans, local shops,
professionals) know they should post consistently on social
media. Most don't — not because they're lazy, but because
they don't know what to write, don't have time, and can't
afford hundreds a month for a marketing agency.

WHAT IT DOES

  • Learns your business profile (sector, city, tone, unique strength)
  • Generates posts per platform: Instagram, Facebook, LinkedIn, TikTok
  • Uses copywriting frameworks (AIDA, Storytelling, BAB, PAS)
    chosen automatically based on your sector and day of the week
  • Hook style adapts to the season and day of the week
  • Built-in editorial calendar
  • All prompting logic is server-side — it took weeks to get the
    AI to write like a real business owner, not a marketing agency

HOW I BUILT IT
Solo project. I'm not a developer — I built the whole thing
using Claude as my co-builder, learning as I went. Single HTML
file + Vercel serverless functions + Supabase.

WHERE I AM
Free beta, invite-only. Looking for feedback before opening
it up more.

WHAT I'D LOVE FEEDBACK ON

  1. Does this feel too crowded, or is "local small business"
    specific enough to stand out?
  2. What would make you recommend this to a small business
    owner you know?
  3. Anything obviously missing?

      Hey! There's an IT/EN toggle in the top right corner of the landing — click EN and the whole page switches to English. Let me know if it works!
