Final Verdict
Mem's AI organisation is genuinely different from note apps like Notion or Obsidian — it removes the burden of manual tagging and filing. For people who capture a lot but struggle with retrieval, Mem's auto-organisation saves significant cognitive overhead. The $14.99/mo price is reasonable for the value to active note-takers.
