Hi HN! We built a SaaS platform to do what we've always wanted and have a Google Docs-like experience without leaving Obsidian. In the process we found a way to enable web access and get non-markdown file sync, too.
There's a one-week free trial if you're interested in trying it out, and I'm happy to answer questions about CRDTs, Elixir, or the other backing tech, too.
