HoloChart vs NotebookLM
NotebookLM analyzes your uploaded documents in the cloud. HoloChart charts any on-screen answer locally.
NotebookLM (2026) is a source-grounded research tool: upload documents and it can run code to analyze the data and produce charts, infographics, mind maps, tables and exportable docs — all grounded in your uploaded sources, in Google's cloud.
HoloChart is a different job: it doesn't ingest a document corpus. It charts the answer that's on your screen right now — from any LLM — locally in the browser, instantly, without uploading your sources anywhere.

When NotebookLM is the better choice

When HoloChart is the better choice
For instantly turning the numbers in an LLM answer into a chart — any model, no source upload, no cloud, no telemetry — HoloChart is the quick, private layer. Different tool, different moment.
