SeekFiles AI vs NotebookLM
Both are citation-first AI for your documents. We're built for the same job — but with different opinions on retrieval, scoping, and what “your library” should actually look like.
Google's NotebookLM is excellent for source-grounded research within a single notebook. It pioneered the citations-on-every-reply pattern, which is a feature we wholeheartedly agree with.
SeekFiles AI differs in three places: we use hybrid retrieval (vector + BM25 fused with reciprocal rank fusion) for better recall on exact terms; we let you scope multiple assistants over arbitrarily large libraries; and we let you share public assistants via link.
