The simple decision
If you use Notion actively and maintain a meaningful workspace, Notion AI's memory update makes it the obvious choice — you're already paying for Notion and the AI add-on extends what you already have. If you don't use Notion and need a dedicated AI knowledge tool, Mem.ai is built specifically for that purpose and doesn't require you to adopt Notion's broader system.
