A free NotebookLM alternative that keeps your sources on-device An on-device Google NotebookLM, Notion AI & ChatGPT alternative.
NotebookLM grounds answers in sources you upload — but those sources go to Google's cloud. Feyard does the same grounding in your browser: chunk, embed and retrieve locally, then generate an answer tied to your exact passages, with no Google account and no upload.
Comparison reflects publicly documented free-tier behaviour as of 22 October 2026. Confirm specifics against each vendor's own page before making a decision.
Sources stay on your device
Indexing and retrieval run locally on WebAssembly / WebGPU. Your notes, papers and reports never leave the browser, so there is nothing to delete afterwards.
Answers are tied to your passages
Every response cites the source document and the specific passage, so you can check a claim against the original instead of trusting a summary.
Mix PDFs and DOCX in one corpus
Build one research corpus from many files and ask across all of them — useful for literature reviews, due diligence and meeting prep.
No Google account, no upload
Start asking immediately. There is no sign-up and no cloud round trip, which also means no retention policy to read.
