I built Sidecar (https://sidecar.bz) because I was having issues maintaining a social media presence for my last startup. I would spend a lot of time trying to create content, but I often froze up or burned out, and the marketing died.
How it works: Instead of guessing what to write, Sidecar connects to your existing accounts (Threads, Bluesky, Mastodon, Facebook, Instagram) and analyzes your past posts to see what actually worked.
It uses that data to generate weeks of new, text-based content that mimics your successful posts, which you can then bulk schedule in one go.
I’d love to hear what you think of Sidecar. You can use code HNLAUNCH for a free month if you want to test the ai features.

For the last few years, I was working on a group travel app called Hoku. The tech was fun to build, but I struggled hard with the marketing side. I ended up building internal tools to help me generate content and keep my social feeds alive while I was coding.
In the end, Hoku didn't get the traction I hoped for, so I decided to shut it down in December. But I realized the marketing tool I built for myself was actually more useful than the travel app.
So I polished it up, packaged it, and that’s what Sidecar is.
It’s basically the tool I wish I had when I started—something to take a raw idea and turn it into a full content calendar so I could get back to building.
