I built an AI design tool, generated 20 posts, and wouldn't have published one of them

Earlier this year I had a working prototype that turned a text prompt into a marketing graphic. I made about 20, looked at them, and realized I wouldn't put a single one on my own account.

You know the look. A half-empty layout, a gray gradient in the background, a button drawn on that leads nowhere, and usually a number the model just invented. It screamed "a machine made this." So I deleted it and spent the next few weeks rebuilding from scratch.

My bar the whole time was uncomfortable and simple: would I actually post this on my own account? For most results the answer was no for a long time.

What changed the output:

• Every design starts from a hand-made template instead of a blank canvas, so it looks designed, not random.

• It reads your brand kit (colors, font, logo) and applies it automatically.

• It checks its own text for contrast and legibility and fixes what fails, instead of shipping unreadable copy.

• You refine by chatting ("make the headline bigger", "shorter") instead of opening design tools.

It's live at postmint.de. One sentence in, a finished post out, in Instagram / Story / Carousel / LinkedIn sizes. Free tier is 10 posts a month, no card.

I'd genuinely value feedback from this crowd on three things:

1. Run one generation. Does the result clear the "would you post this" bar, or where does it still look off?

2. Did anything in the flow make you hesitate before you even generated? (My worst number is people who sign up and never try it.)

3. The landing page and positioning: does it land, or what's confusing?

Tear it apart. I'd rather hear it here than not.
