Pros & cons
Craft AI
Pros: Document-style structured AI works inside Craft's writing surface rather than as a chat overlay.
Cons: Craft's overall PKM market share has shrunk; AI is an enhancement layer, not a memory product.
Notion AI
Pros: Memory is grounded in workspace pages — what AI knows is exactly what's in your Notion, not a hidden vector store.
Cons: Not persistent learning — does not remember interactions, only summarizes existing pages; 50-page-per-query ceiling at typical workspace size.
