If you’re an author, you’re probably drowning in material. Drafts, notes, interviews, research PDFs, blog posts, launch plans – all scattered across folders, inboxes and apps. NotebookLM, Google’s “AI over your own sources” tool, is one of the first assistants that actually helps you manage that mess rather than add to it.
In the last year or so, NotebookLM has quietly grown from “interesting experiment” to a serious research‑to‑content engine. It can now run deeper research on your topic, turn your sources into slide decks, infographics, flashcards, quizzes and briefing docs, and even create audio overviews you can listen to like a private podcast.
For authors, this is gold – especially if you write non‑fiction, complex series fiction, or you’re running a business around your books.
What exactly is NotebookLM?
NotebookLM is a free Google tool that lets you upload your own material (docs, PDFs, web pages, transcripts) into a “notebook” and then talk to an AI that only works from those sources plus any outside research you explicitly allow.
You can ask it to:
- Summarise and compare multiple documents, with citations back to each source.
- Pull out themes, timelines, character lists, terminology and contradictions.
- Generate ready‑to‑use outputs: study guides, quizzes, flashcards, slide decks, infographics and more.
Think of it as a private, citation‑backed research assistant that lives on top of your own library.
Why it matters specifically for authors
Here are some practical author use‑cases I’ve tested and seen others use:
- Research notebooks: upload articles, papers and interviews for a book, then ask for chapter‑by‑chapter research summaries, arguments for/against a position, or gaps you still need to fill.
- Series bibles: feed in past books, notes and world‑building docs, then query continuity details (“When did X first meet Y?”, “What was Z’s injury in book two?”).
- Marketing assets: take one long‑form piece (your book, a keynote, a long blog post) and spin out launch emails, social posts, sales pages and podcast talking points – all grounded in the original text.
- Teaching and training: if you run courses, you can turn your material into flashcards, quizzes, slide decks and study guides in a few clicks.
For many authors this is the difference between “I’ll get to that someday” and “I can ship this this week”.
But what about British English?
One legitimate annoyance for UK authors is that AI tools default to US spelling and phrasing. NotebookLM is improving here, but the controls are still a bit hidden.
A few key points:
- NotebookLM takes a default language from your Google account settings, and also offers an “Output language” option inside its own settings.
- Audio Overviews and text answers follow that output language, and Google now supports 50+ languages for audio – English included – with more refinement over time.
- The interface doesn’t yet list a neat “English (UK)” toggle everywhere, so you need to guide it.
What works in practice:
- Set expectations in the very first message in each notebook. For example: “Use British English spelling and punctuation throughout (colour, organisation, programme). Match the tone and style of my uploaded documents.”
- Seed the notebook with documents that use consistent UK spelling – your existing blog posts, a chapter of your book, or a style sheet. The model tends to mirror the spelling it sees in sources.
- When you create Studio outputs (slides, infographics, flashcards, study guides), add a line to your prompt: “Ensure all on‑screen text uses British English spelling.”
It’s not perfect yet, but it’s now good enough that the odd stray “organize” is the exception, not the rule.
A simple NotebookLM workflow for your next book
Here’s a straightforward way to try NotebookLM on a real project:
- Create one notebook per project
- For example: “Book – Working Title”, “Author Platform”, or “Course – X Topic”.
- Upload your manuscript draft, outline, research PDFs, key blog posts, and any launch plans you already have.
- Set your “house rules” in the first prompt
- Tell it who you are, who the book is for, and the tone you want.
- Add: “Use British English spelling, and answer like a professional editor talking to an experienced author.”
- Use question prompts to stress‑test the book
- “What are the three strongest arguments in this book, and where do they feel weakest or thinly supported?”
- “List any repeated stories or examples that could be cut or combined.”
- “Where might a new reader feel lost or overwhelmed?”
- Turn the same sources into marketing assets
- “Using only my uploaded sources, draft a back‑cover blurb in 120 words, British English, aimed at [target reader].”
- “Turn this book into: a five‑email launch sequence, five LinkedIn posts, five short YouTube scripts, and a 1‑page sales letter.”
- Create teaching and “extras” with Studio
- Use Studio to generate flashcards, quizzes and study guides if your book lends itself to learning material.
- Spin up slide decks and infographics you can use in talks, webinars, or course modules.
You do the quality control and final editing; NotebookLM does the first 80% of the legwork.
Where NotebookLM fits in AI for Authors Circle
Inside AI for Authors Circle, NotebookLM sits next to tools like Perplexity, Gemini and ChatGPT as part of your “author tech stack”.
My recommendation for Circle members:
- Use NotebookLM any time you’re working from your own heavy material (books, research, courses, archives).
- Use general chat models when you want fresh ideas, market research, or “blank page” brainstorming, then feed the best of that output back into NotebookLM as part of your project notebook.
The real win is making your past work searchable, reusable and sellable – and NotebookLM is one of the cleanest ways to do that right now.
