Frequently asked
Are Tana and NotebookLM substitutes or complements?
Complements. Tana is your long-term knowledge system. NotebookLM is a focused tool for specific source comprehension. Many power users feed insights from NotebookLM into Tana.
Why is NotebookLM free?
Google strategy. NotebookLM showcases Gemini in a clear use case while collecting research data. Free tier is generous (50+ sources, unlimited queries). The trade-off is no privacy guarantee for source content.
Is Tana worth $14/mo for casual users?
Probably not. Tana power comes from structured supertags and complex queries that take time to learn. Casual note-takers usually do better with Notion, Reflect, or even Apple Notes.
Which has better AI?
NotebookLM has the stronger underlying model (Gemini) and produces more accurate document Q&A. Tana AI is well-integrated for capture and structuring but less sophisticated on raw answering.
