Porchsongs.ai; Rewrite chordcharts/lyrics with AI to make them personal

I posted porchsongs here about a month ago as a self-hosted Docker project. A few people looked at it, but I get that spinning up docker containers and configuring stuff is sort of a big ask.

So I went ahead and built it into an actual hosted platform. Core is still fully usable and OSS but now I offer a hosted option.

I'M OPENING IT UP VIA AN INVITE CODE. Here's one for the first 100 HN users so my LLM token budget doesn't immediately go to zero haha:

PORCH-7F95BB

tl;dr backstory. I'm a guitarist who loves playing songs on my porch over the summer, and I wanted a platform that let me:

1. Easily access a library of chord charts i like to play and render cleanly on my phone so I can use that to read the music 2. AI assisted rewriting so that I can make songs more personal or quickly sketch up a song. A year ago LLMs struggled but Claude Sonnet and Opus 4.6 are EXCELLENT. I was shocked at how good they are

What's changed since my last post: - You can just sign up and use it now via Google OAuth or email magic link - Rewrites stream back in real-time - Personal song library to keep your versions - The OSS repo is still there: https://github.com/njbrake/porchsongs

Happy to talk about the tech or whatever else. Building a truly working public OSS core and a private 'hosted' codebase was a very education process that I learned a lot from building.

Building and connecting stripe, GCP, nano.tech, resend, sentry, etc was a lot of fun (and also a lot of work )
