Frequently Asked Questions
Is Obsidian AI worth the subscription cost?
+For serious knowledge workers, absolutely. The AI features significantly enhance linking, discovery, and content generation while maintaining Obsidian's core values. Casual users may find the free version sufficient.
How does local AI processing work in Obsidian?
+Obsidian can integrate with locally-run LLMs (like Llama 3 or Mistral) through plugins. This keeps all processing on your device but requires substantial RAM (16GB+ recommended) and technical setup.
Does Obsidian AI use my private notes for training?
+No. With local AI, your data never leaves your device. Even with cloud AI options, Obsidian states they don't use your data to train public models.
Can I use Obsidian AI for team collaboration?
+Currently, Obsidian focuses on individual knowledge management. For teams, you'd need to sync vaults manually or use third-party solutions, which limits real-time collaboration.
How does Obsidian AI compare to using ChatGPT with Obsidian?
+Obsidian AI is deeply integrated with your vault's content and structure, offering context-aware suggestions that generic AI tools can't match. While ChatGPT can be used alongside Obsidian, the native integration provides more relevant, personalized assistance.
