Hey HN,

we built Postel to help makers, indie hackers, and marketers consistently publish great content across Reddit, X, and LinkedIn - without starting from scratch every time.

  The core idea: your product docs, notes, stories, landing page and personal insights already hold all the content you need. You just need a layer to translate them into platform-native posts.
Postel uses a RAG and thousands of scraped viral posts from LinkedIn, X, and Reddit. This ensures the generated content follows the structure of high-performing posts for each platform while being relevant to your context.

This is a tool we wanted for ourselves. Between the three of us (Robin, Bruno, and Joschua), we’ve built and shipped several projects, but writing consistent, “on-brand” content was always a bottleneck. Especially for Reddit, where self-promo is hated. Postel helps you with ideas and to get the first draft right.

It’s still very early access. We launched the MVP just two weeks ago and have the first 17 paying users creating content. (The roadmap is stacked tho...)

We'd greatly appreciate any feedback you have and hope you get the chance to try out Postel.

Cheers, Joschua
