FolianX stops at connected notes and team knowledge. That means fewer surfaces to configure, but it also means no relational database, kanban board, calendar view, native app or offline mode. Those omissions are product boundaries, not features hidden on a higher plan.
The MCP difference is control shape. FolianX tokens are explicitly read-only or read-write, are stored only as hashes and can be revoked immediately. They follow everything the token owner can see and cannot yet be limited to one teamspace. Notion MCP also connects external assistants and respects the connecting user's Notion permissions.
The export difference is workflow, not availability. Both products export a workspace. FolianX offers direct page Markdown and a workspace zip; Notion exports HTML, Markdown and CSV, with PDF workspace export on specified plans. An export from either product may need cleanup before another product can recreate its structure.
