What the models actually said.
The ranking is the answer; these are the words behind it. Every quote is from a recorded model answer — follow the category to read it whole.
Capacities
Capacities — Best for knowledge workers who naturally organize information around people, projects, books, and ideas, since its object-based model and daily notes create structure without requiring extensive upfront taxonomy design.
ChatGPT
Mem
Mem — Best for AI-first quick capture if you want the app to help you collect notes rapidly, but it is less of a long-term knowledge-base tool than Obsidian or Notion.
Perplexity
Where the models split.
Across the 1 category Capacities and Mem both appear in, the models never break ranks: in each one, the same brand leads on ChatGPT, Claude, Gemini, and Perplexity alike.
No model runs against the grain here: each of the four ranks Capacities ahead at least as often as not, with Perplexity the most lopsided.
