+## Out of Scope
+
+| Feature | Reason |
+|---------|--------|
+| Real-time collaboration | Personal tool, single user — massive complexity for no value |
+| Multi-user authentication | Single-user by design, no need for user management |
+| AI-powered categorization | Over-engineering; manual tags are clearer and simpler |
+| Complex folder hierarchies | Flat + tags is more flexible; nesting creates friction |
+| Kanban boards | Overhead for personal tasks; simple list is enough |
+| Multiple note types | Task/thought distinction is enough; more types complicate model |
+| Social features | Out of scope for self-hosted personal app |
+| Heavy WYSIWYG editor | Bloated and complex; plain text or defer to Markdown |
+| Push notifications | Browser notifications are unreliable and annoying |
+| Version history | Storage overhead; simple edit is fine for personal use |
+| Mobile native app | Web-first; browser works on all devices |
