Docling vs NotebookLM
Docling scores 64 to NotebookLM's 19 on public evidence for chat with PDFs & documents, and they rank #3 and #4 there. Both are free to start. Numbers below are the same public signals the ranking uses, recomputed nightly — nothing here is sponsored.
Docling
Turns PDFs, Office files and scans into structured markdown or JSON, layout and tables intact.
+ Reads a table as a table, and does it on your own machine with nothing sent anywhere.
− Heavy scanned documents want a GPU; CPU-only runs are slow on long PDFs.
NotebookLM
A grounded research notebook that answers only from the sources you upload and can turn them into Audio Overview podcasts.
+ Answers are grounded strictly in your uploaded PDFs, Docs, URLs and YouTube videos with citations, and Audio Overviews turn them into a two-host podcast.
− Sources are capped per notebook and the free tier limits daily queries and audio generations.
