Notion vs Obsidian: what people say

Notion

Notion is widely loved as a flexible, customizable all-in-one workspace, and its tutorials and templates are a major driver of goodwill and sign-ups. The biggest recurring problems are complexity and overwhelm for beginners, endless tinkering instead of real work, and frustration with unwanted AI features that can't be turned off. Data safety is a serious worry, with reports of lost notes, workspace lockouts and a breach exposing AI chat transcripts. Obsidian is the most-cited alternative, especially for people who want local files and no AI, and open-source clones keep getting pitched as replacements. A surprise is how much of the conversation is really about creators' templates and courses rather than the product itself.

Obsidian

Obsidian's biggest strength is its local, plain-markdown foundation, which users repeatedly describe as the natural home for AI-generated notes and a safe, portable place for their knowledge. The CEO's own vault, skills and workflow videos are a major draw, and the new CLI is the most talked-about feature, exciting power users while raising headless and sync questions. The loudest complaints are that second-brain setups can be productivity theater, that AI over a vault is token-hungry and error-prone, and that Obsidian is not actually open source. Beginners keep asking what Obsidian is really for and how to start, while many say they are switching from Notion or Evernote after watching a tutorial. A recurring surprise is how many people question whether Obsidian is needed at all when a plain folder plus Claude might do the job.
