Our take
Pick Heptabase if students and researchers who will pay Premium so OCR, GPT/Claude agents, and more than 100 Gemini-only credits sit on one whiteboard. 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).
