Six months ago, I built JustGrind, an AI habit coach. Coding it was fun; shipping it? Nightmare. Marketing it? Even worse.
I realized the hardest part of building a product isn’t the coding—it’s getting people to actually see it. So I built Postnix AI, a tool that helps indie hackers, creators, and solo founders craft posts that get attention:
- Fetches top-performing posts in your target communities
- Analyzes what makes them work
- Helps you write your own posts that feel natural and hit the right vibe
- Suggests flairs, formatting, and style tweaks that increase visibility and engagement
Key lesson: no matter how good your product is, if nobody knows it exists, it doesn’t matter.
It’s still early days, but people are already getting traction with their posts. Would love feedback from the HN community!
