I built the honest version of ChatGPT for startup ideas [GO, PIVOT, or NO-GO in 60 seconds]

That app idea that's been sitting in your head for months?
I built something to finally give it a straight answer.

You know the one.

The idea you keep coming back to. You've never properly
looked into it because you're not sure if it's worth the
time. You've probably asked ChatGPT - and got back
"innovative concept with strong market potential."

Useless.

The real problem with using AI to validate ideas is that
you have to engineer long, careful prompts just to stop
it from cheerleading you. And even then, you're not
confident you're getting a straight answer.

I built Vett to fix this.

Vett thinks like a senior CTO reviewing a pitch. It has
one job: tell you the truth about your idea before you
waste months building the wrong thing.

You describe your idea. Vett tells you:

→ Whether the market is underserved or already too crowded
→ The specific gap your angle could actually own
→ A hard GO / PIVOT / NO-GO verdict with real reasoning
→ If it's a PIVOT - the exact better opportunity to move
toward instead

For ideas that get a GO, it also generates:
→ A 13-slide investor pitch deck (.pptx, instant download)
→ A full MVP build doc with copy-paste Lovable prompts

Built nights and weekends in Lisbon. Live now at
vettmyidea.com - free to try, no account needed.

Three things I genuinely want feedback on:

  1. Do you trust an AI verdict enough to kill an idea
    based on it?
  2. What would make you pay $9 for the pitch deck +
    build doc?
  3. What's the idea that's been sitting in your head
    the longest?

Drop it in the comments. Genuinely curious, and I'll
run it through Vett live if you share it.
