Show HN: Nom – Turn GitHub activity into updates

Hey HN,

I built Nom because I kept running into this problem: code moves way faster than we can update people about it. I'd ship features, merge PRs, close issues, and my users had no idea unless I sat down and wrote a changelog or posted about it on X.

Nom turns your GitHub activity into a social feed. You install the GitHub App and every PR merge, issue, release, and comment gets auto-summarized by AI into something actually readable. Think of it like an X feed for your repo.

You can customize the AI prompts per-repo (just drop a template in .nom/), subscribe to projects you care about, and share your feed publicly.

Stack: Next.js, Supabase, Trigger.dev for background jobs, GPT-5.2 for summarization.

Why I built this: there are more builders shipping faster than ever (thanks, AI). But keeping your community in the loop still takes real effort. Writing changelogs, posting on socials, updating Discord. Nom automates the "what happened" so you can focus on the "what's next."

Live at https://beta.nomit.dev and open source at https://github.com/nom-social/nom.

Would love feedback. What other GitHub events would you want in a feed like this?
