The README has had plenty of LLM help, yes. I’ve described how I use them here: https://syncular.dev/llms/

I’ll keep refining it (talking about docs, tests, benchmarks etc). LLMs are involved throughout Syncular, as they are in my other projects, but this sure wasn't prompted into existence, its been built on and off over a lot of time. Have spent years deep in the offline-first rabbit hole. Most code, design and its trade-offs come from that experience and predate LLMs.
