But I realized several years ago that offline first is always my first requirement for a tool like this—no SaaS, no subscriptions (or freemiums), no storing important info in yet another cloud, no signups, nothing. I write markdown locally, convert it to whatever I need locally (PDF, EPUB, etc.).

I think I’d use your tool as more of a ‘whiteboard’, where I could temporarily share simple information that’s not critical or private or work-related, that I don’t mind the world seeing. Would I pay for that service? Probably not.
