The relationship between notes is weak, so it's more of a text editor tool than a PKM tool.

Mem

Mem has more accurate AI chat than any other AI-based PKM tool.
The ability to suggest related notes also appears to be superior to Reflect Notes, which has the same functionality.
Currently, there are no properties or advanced search queries, so the collection of information on the notes created will depend on the results of the AI.
Unlike search methods such as Notion's database or Obsidian's Dataview, AI-based searches facilitate new discoveries. (AI-based is still unreliable when exact results are always required.)
The concern I have with Mem is the infrequency of service updates.
A major renovation, "Mem 2.0," is scheduled for the end of 2024, so we look forward to that.
