NotebookLM or Liminary

Choose between document-QA in a tab (NotebookLM) or connected knowledge across your workflow (Liminary).

Choose Liminary if you want a persistent knowledge base that grows with your career, rather than temporary notebooks that end with the tab.

Google's NotebookLM lets you upload documents, ask questions about them, and get cited answers. For quick document analysis, it's useful and free. Many professionals have started using it to make sense of research papers, reports, and interview transcripts.

But NotebookLM is session-based. You upload files, work with them, and when you close the tab, the workflow ends. Nothing persists. Nothing connects to the next session, the next client, or the next project. And it doesn't follow you into the tools where you actually produce your work.

Where NotebookLM stops

NotebookLM is a document QA tool. You upload sources, you ask questions, you get answers. That's valuable for a focused research session. But it has architectural limits that matter for ongoing professional work.

Each notebook is isolated. There is no cross-notebook search, no way to query across projects, and no persistent knowledge base that grows over time. Every new notebook starts from scratch. Your insights from last quarter's project don't carry into this quarter's work.

NotebookLM also lives entirely inside its own interface. It doesn't surface insights while you write in Google Docs, it doesn't capture your meetings, and it doesn't monitor your market. It answers questions when you ask them, inside a single tab.

Where Liminary goes further

Liminary is built for the knowledge that accumulates across your career, not just a single research session. Save articles, upload documents, capture meetings, and build collections by client or topic. Everything is queryable, everything persists, and everything connects.

The critical difference: Liminary follows you into your writing environment. Recall (Our Tiny Core Superpower) surfaces relevant knowledge in the Google Docs sidebar while you draft a proposal, a report, or a client email. You don't leave your document to search. The knowledge finds you.

What Liminary adds that NotebookLM doesn't

Persistence across sessions. Your knowledge base grows over time. Research from six months ago is as accessible as research from this morning.

Chrome extension. Save web pages, articles, PDFs, and videos to your knowledge base with one click while you browse. NotebookLM requires manual file uploads.

Recall in Google Docs. Liminary surfaces relevant context from your entire knowledge base while you write. NotebookLM can't reach outside its own interface.

Google Meet integration. Meeting transcripts flow directly into your collections and become part of your queryable knowledge. NotebookLM has no meeting capture.

Competitive intelligence agents. Agents monitor topics, companies, and competitors on a schedule and surface findings into your collections. NotebookLM is entirely manual.

Shareable collections. Build a public collection that anyone can query, or share a collection with colleagues. NotebookLM sharing is limited to individual notebooks.

1.7x more accurate on hard questions than Ask Gemini. In our own benchmarking, Liminary scored 88.9% accuracy on multi-document questions versus 72.7% for Ask Gemini (the same engine powering NotebookLM). On hard questions where the answer is not in the file name or needs to be inferred, Liminary was 1.7x better than Ask Gemini while being more than 50% faster.

Who should use what

NotebookLM is a good starting point for one-off document analysis and research sessions. It's free and simple.

Liminary is for professionals who need their knowledge to persist, connect, and surface while they work. If you've tried NotebookLM and wished it remembered what you uploaded last week, followed you into Google Docs, or connected your meeting notes to your research, Liminary is the next step.
