Real-time collab. AI Author with surgical edits, not chat. A public REST API for Zapier and n8n. Your bytes stay yours — every doc exports to .md verbatim.
The tools you already have — and why they don't quite work for the docs that aren't code.
Markdown source is great. Markdown rendered is a postage stamp in a preview pane that nobody on your team wants to read.
The same Markdown, rendered as a real document. ⌘E toggles back to source when you want it. Same .md round-trip in and out.
Issues and READMEs render fine. But there's no folder, no doc-level permissions, no real comments, no draft state.
Folders, ACLs, comments anchored to selections, autosaved drafts, version history. Public links for stakeholders who don't have GitHub accounts.
You agreed to write the RFC in Notion because the PMs use it. You hate every keystroke. The markdown export is lossy.
Markdown-native source. Imports your existing Notion .md exports cleanly. PMs get the same shareable link.
