Verdict
Vibe-code a personal wiki or CRM-lite. Do not aim to replace Notion for a team. The hard part is collaboration and reliability, not the first empty page.
What you can rebuild
A personal notes app with nested pages, markdown editing, simple databases (tables with filters), and sharing links. Enough for a solo second brain demo.
What stays hard
Realtime multiplayer editing, permission trees, offline sync, formula engines, and the block editor polish people expect from Notion. Also marketplace templates and integrations.
Starter prompt
Build a Notion-like workspace MVP called PageNest. Users can create nested pages, write in a block editor (paragraph, heading, bullet, todo, simple table), organize pages in a sidebar tree, and share a page via public link. Stack: Next.js, Tailwind, Supabase auth + Postgres. Keep the UI clean and minimal. Ship: signup/login, create/edit/delete pages, nested sidebar, public share toggle, and a basic database view (table with text and select columns).
Follow-up prompt
Add: drag-and-drop page reordering in the sidebar, comments on blocks, page templates (meeting notes, project brief), and row-level filters on the database view. Do not add realtime multiplayer yet. Prioritize mobile-friendly reading.
