Ounie vs Google NotebookLM
Ounie and NotebookLM share the same core promise: answers grounded only in your own sources, cited back to where they came from. The difference is what happens around the answer. NotebookLM is built around a single notebook of documents. Ounie is built to be a permanent second brain — it synthesizes every source into an interlinked wiki, builds a knowledge graph for you, and is reachable from your other tools through an API and MCP.

Ounie vs Google NotebookLM: common questions
Is Ounie a good NotebookLM alternative?+
Yes. Like NotebookLM, Ounie answers only from the sources you add and cites them. Ounie goes further by synthesizing each source into an interlinked wiki, building a knowledge graph, and letting you share, embed, or sell a brain — plus API and MCP access so other AI tools can use it.
Does Ounie cite its sources the way NotebookLM does?+
Yes. Every answer links back to the exact pages it drew from, and when your sources don't cover a question Ounie says so instead of guessing. Citations are resolved against the pages actually retrieved, so they're never fabricated.
Can Ounie read the same file types as NotebookLM?+
Ounie reads PDFs, Word documents, images (via OCR), audio and video (via transcription), web links, and plain notes. You can mix all of them in one brain.
Does Ounie make audio overviews like NotebookLM?+
Not today — Audio Overviews are a genuine NotebookLM strength. Ounie focuses on a persistent, cited, interlinked brain you can ask, share, and connect to your other tools.
