As a tech lead/architect of 20 years in the startup industry I'd say %70+ of my time is spent communicating concepts to engineers and to the business. My primary tools for this have always been diagrams and wikis, and with the arrival of Notion I've found myself rolling in the clover so to speak of communication goodness.I also do a fair bit of personal writing, and traditionally I have used VIM (with prose add-ons like Pencil, Goyo etc.) to accomplish this however six months ago I switched the book I am working on across to Notion.The experience has been largely a good one; I can easily create links to notes, maintain pages of background information and research on the various topics in my book as well as use it as a link-dump from my phone. I frequently bullet-point outline ahead of myself and bold/italic things that need re-work, all features that I never could do (well) in VIM/Markdown.However, I miss my ability to go off-grid with my laptop and write, I miss my ability to check-in my commits to a personal git repository, I miss the ownership I had knowing that my data was in my own hands.  HN, what can you recommend as a good WYSIWYG personal notion/wiki replacement?
