Why You Should Trust This Review
I migrated the same 200-note knowledge base into both tools and ran identical retrieval, summarization, and writing tasks for 30 days.
Round 1: Knowledge Retrieval ("Ask my notes")
- Notion AI: Q&A across your workspace with surprisingly good citations.
- Obsidian Copilot: Vault search via embeddings — accurate, but you set up the embeddings yourself.
Winner: Notion AI for ease of use; Obsidian Copilot for control.
Round 2: Writing Inside Notes
- Notion AI: Frictionless inline writing, summaries, and translations.
- Obsidian Copilot: Excellent — and you can swap models (GPT-4, Claude, local Llama).
Winner: Tie.
Round 3: Data Ownership
- Notion AI: Your notes live on Notion's servers.
- Obsidian Copilot: Local markdown files. Total ownership.
Winner: Obsidian Copilot.
