What engineers like:
JSON export to a batch of Markdown files, packed under NotebookLM's 500,000-word per-source cap, never splitting a record across files. Incremental re-runs: point it at the same export later and only the new records go up. YouTube playlists and channels: each video becomes its own source, with transcript and optionally the top comment threads. Link lists: each URL becomes a source; for pages NotebookLM cannot fetch, the text is read from the tab you already have open. Nothing is downloaded to disk - files are built in memory and sent to the notebook page's own origin. No backend and no account: your Google session never touches a server of ours. Unminified code under the PolyForm Noncommercial licence - source-available, not open source. Chrome and Edge. Free plan: 5 bulk uploads a month; Pro is $29 one time, not a subscription.
Best suited for:
Load a large JSON or chat export into a notebook without hand-splitting it into files that fit the per-source cap. Turn a YouTube playlist or channel into a research notebook, one source per video, transcripts included. Feed a reading list of links into NotebookLM in one pass, including pages NotebookLM cannot fetch on its own. Keep a notebook in sync with a growing export: re-run it and only the new records are added. Work with material you would rather not download to disk or route through a third-party server.
