Pros & cons
Microsoft Recall
Pros: Most aggressive ambient capture of any major OS — every screen seen is searchable, then queryable.
Cons: Drew significant privacy backlash on launch (May 2024); only Copilot+ PC hardware supported.
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.
