How to choose
Start with integration depth: Obsidian users should pick ZettelkastenAI or open-notebook first. Local privacy needs point to open-notebook or Second Brain for Mac/Windows. Team video workflows favor Mnemcore. Watch for export limits and recurring billing outside the listed platforms; test semantic search quality on your actual note volume before committing. Avoid pure export utilities like NotebookLM-to-PDF when core capture and linking are required.
