Our take
Pick Capacities if researchers and makers who will pay Pro so AI, calendar, and PDF analysis sit on the Free object graph. Pick Mem if solo knowledge workers who will live in one Mem inbox and pay when the 25-message Free cap bites. Skip Mem if teams that need a shared workspace wiki (Notion AI) or a meeting recorder first (Otter.ai).
