## ShipRadar verdict

Handy for a single PDF Q&A with citations. Skip Plus if NotebookLM already covers your stack of files for free.

- Best for: Dropping one PDF in the browser and asking a few questions with page citations, without a Google account.
- Not great for: Working across many sources at once. NotebookLM is free for that.
- Watch out: Free allows 2 documents a day. Plus is about $19.99 a month in independent checks, which is steep next to free NotebookLM for multi-file work.
- Consider instead: https://shipradarai.com/tool/notebooklm, https://shipradarai.com/tool/claude
