Show HN: Sóþspell, a model-guided walkthrough of a codebase

I kept finding myself wanting a way to get talked through the code that a model had created, which led to me making Sóþspell (old English, "Truth Story"). You give it a git repo locally or via URL, and it creates a tour of the repo in a web page, with the aim of it explaining the whole thing. There's also model harness plugins for Claude, Codex, and OpenCode. You give it an API key for whatever model you prefer to create the tour (saved locally or via github), and you can also give it a voice using an ElevenLabs API key. I just pushed a canvas view, which I'm hoping I can make the code navigation a bit more helpful. There's a demo codebase, and you can export tours as JSON. The demo doesn't need any keys to work, it falls back to browser speech if you want to hear that. This is my first real, "big" open source project that I've released, prior to this I'd just contributed stuff. I hope it can be useful to someone! I would love to hear some constructive criticism too, and any suggestions on features you'd like to see. It's MIT licensed, and I'll try to stick around in the comments to answer questions if people want. Comments URL: https://news.ycombinator.com/item?id=50245022 Points:
