Notion AI
https://www.notion.com/product/ai
Notion's first-party AI. Reads up to 50 pages per query (as of Jan 2026); Custom Instructions persist brand voice / team structure / preferences. Context follows you across model swaps. Notably not persistent cross-session learning — it organises and summarises what's in Notion rather than learning from interactions.

Optimised for: personal-knowledge-management UX + AI-augmented note-taking
Anti-fit: not for enterprise / programmatic use; not for compliance-regulated workloads
Pros & cons
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.
