Show HN: Sidecar – AI Social Manager (Analyzes past hits to write new posts)

Hi HN,

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.
