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.
RemNote AI
Pros: Built on a spaced-repetition substrate — memory has explicit retention scheduling, unlike most note tools that retrieve on demand.
Cons: Smaller user base than Notion / Obsidian; AI features lag general-purpose PKM tools.
