Show HN: I built a tool that turns GitHub commits into posts

https://postezi.com
2•rudolfsrijkuris•1h ago
Hi HN,

I'm the solo developer behind Postezi.

The idea came from a problem I kept running into: I'd ship features almost every day, but when it came time to write about them on LinkedIn or X, I'd stare at a blank editor for 20 minutes and eventually give up.

I realized Git commits already contain most of the context needed to describe what changed. The missing piece is collecting that context, understanding it, and turning it into something readable.

So I built Postezi.

I hope this tool will be as helpful to you as it is for me. Would love your feedback pls
