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.
Google Keep
Google Keep – The best lightweight option for quick capture, checklists, and reminders, especially if you're already living in Google Workspace.
Claude
Obsidian
My default recommendation for an individual knowledge worker: Obsidian.
ChatGPT
Google Keep
Google Keep: The weakest for comprehensive course notes, but highly recommended as a supplementary tool for quick, sticky-note style ideas, to-do lists, and fleeting thoughts.
Gemini
Obsidian
Obsidian — Best for serious long-term learners who want to own their files and build a deeply linked personal knowledge base, but it ranks below the top three because the setup and habits take more effort.
ChatGPT
Where the models split.
Across the 2 categories Google Keep and Obsidian 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 Obsidian ahead at least as often as not, with Claude the most lopsided.
