The Real Difference
Both offer free tiers, so the real question is what you get when you start paying.
Capacities stands out with Object-based note system and Daily notes and journals. Mem counters with AI-powered search and organization and Automatic note connections.
Capacities's Achilles heel: young product with missing features — no api, limited integrations, and collaboration is early-stage. Mem's: ai magic is hit-or-miss — sometimes surfaces gold, sometimes nonsense, and you lose control over structure. Pick whichever weakness you can live with.
Bottom Line
If you value object-based note system and visual thinkers who want, go with Capacities. If people who hate organizing matters more, Mem is your pick. Neither is a bad choice — but one will fit your workflow better.
