How to Use NotebookLM to Create a Podcast in Under 10 Minutes

Go to notebooklm.google.com and sign in with your Google account u2014 it's free. Create a new notebook, then click 'Add Source.' You can upload PDFs, paste in a YouTube link, add a Google Doc, or even paste raw text. I recommend starting with one solid source: a training document, a recorded webinar transcript, or a detailed blog post you've already written. Once your source is uploaded, scroll down to the Audio Overview section on the right panel and click 'Generate.' NotebookLM will take 2-5 minutes to produce a roughly 10-15 minute two-host audio discussion of your content. You can then download the MP3 file directly. One tip I always share with my students: add a brief instruction in the notebook's custom instructions box telling the AI who the target audience is. Something like 'This is for Dubai real estate agents new to AI tools' will make the conversation tone much more relevant and practical.

What Types of Content Work Best as Sources

Not all source material produces equally good results. In my testing, the best inputs are documents with clear structure u2014 headings, bullet points, defined sections. A GoHighLevel setup guide or a real estate marketing checklist will generate a much tighter audio overview than a raw stream-of-consciousness transcript. That said, YouTube video links work surprisingly well because NotebookLM pulls from the auto-generated captions. I've used this with my own YouTube videos to create podcast-style summaries that I then share as bonus content for course students. For my clients in real estate, I recommend uploading property brochures plus one market report. The AI will synthesize both into a single conversation u2014 something like a host saying 'So given what this report shows about off-plan supply in Dubai, how does this project actually stand out?' It's that synthesis capability that makes it genuinely more useful than a transcript reader. Avoid uploading scanned image PDFs u2014 NotebookLM needs actual text, not images of text.

Turning NotebookLM Podcasts Into a Content Distribution Strategy

One audio file is just the start. What I recommend to my course students is a simple three-step distribution flow. First, download the MP3 and upload it to Spotify for Podcasters (free) u2014 this alone gives you a published podcast episode with a shareable link. Second, run the audio through a transcription tool like Otter.ai or even Whisper to get a written transcript, then clean it up into a blog post or newsletter. Third, pull 3-4 of the best quotes or insights from the podcast conversation and turn those into short-form social posts or Reels scripts. One document becomes a podcast, a blog post, and five social captions. I've seen clients in Dubai build an entire content calendar for a month using just four of their existing sales training documents. The specific action you can take today: open NotebookLM, upload one PDF you already have u2014 a course module, a brochure, a client guide u2014 and generate your first Audio Overview. It costs nothing and takes less time than writing a single email.

📚 Article Summary

Most people are sitting on a goldmine of content they’ve never thought to use. PDFs, training videos, recorded Zoom calls, course notes, sales scripts — and all of it just collects digital dust. I started experimenting with Google’s NotebookLM about a year ago, and it completely changed how I repurpose content for my students and clients. What used to take a video editor and a podcast producer can now happen in under 10 minutes, for free.NotebookLM is a research and content tool from Google that can ingest your documents, videos, and notes — and turn them into a natural-sounding, two-host audio podcast called an Audio Overview. It’s not a robotic text-to-speech reader. The two AI voices actually discuss your content, ask each other questions, and summarize key ideas in a way that sounds like a real conversation. The first time I fed it one of my GoHighLevel training PDFs and heard it explained back to me like a podcast episode, I knew this was something worth teaching.In my experience training agents in Dubai, the biggest content bottleneck isn’t ideas — it’s production time. A real estate agent might have 30 client call recordings full of objection-handling gold, but no time to turn them into YouTube videos or blog posts. NotebookLM solves this. You upload the recording (or a transcript), and within minutes you have an audio file you can post on Spotify, embed on your website, or share in a WhatsApp group. I’ve seen clients go from zero podcast presence to 10 episodes published in a single afternoon.What makes this genuinely useful — not just a novelty — is that it pulls from YOUR source material. It doesn’t hallucinate or add generic fluff. If you upload a 40-page PDF about Dubai off-plan properties, the podcast it generates will talk about Dubai off-plan properties. That specificity is what makes the output actually valuable for your audience. This isn’t a tool for content farms. It’s a tool for people who already have expertise and knowledge locked in documents they haven’t fully used yet.

❓ Frequently Asked Questions

Yes, NotebookLM is free to use with a Google account at notebooklm.google.com. There is a paid tier called NotebookLM Plus, available through Google One AI Premium at around $19.99/month, which offers more notebooks, longer audio generation, and priority access. For most individuals and small business owners getting started, the free tier is more than sufficient u2014 you can generate multiple Audio Overviews per day and upload up to 50 sources per notebook.
NotebookLM accepts PDFs, Google Docs, Google Slides, plain text files, and copied text. You can also add YouTube video links (it pulls from the video's captions), website URLs, and audio files. The main limitation is that scanned image PDFs won't work because there's no machine-readable text in them. For best results, use text-based PDFs, Word documents saved as PDFs, or directly pasted content. Each source can be up to 500,000 words.
Audio Overviews typically run between 8 and 20 minutes depending on the volume and complexity of your source material. A single 10-page PDF might produce an 8-minute episode; a 60-page report or multiple sources combined could generate a 20-minute conversation. You cannot set a specific target length, but uploading more sources generally produces longer output. If you want a shorter episode, use fewer or shorter source documents.
As of early 2026, you cannot change the two AI voices or directly edit the generated script before the audio is produced. However, you can influence the content by writing custom instructions in your notebook u2014 for example, specifying the audience, the tone (more formal vs. casual), or topics to emphasize. You can also ask NotebookLM to regenerate the Audio Overview after updating your instructions. The voices are fixed English-language speakers, and the tool currently does not support other languages for Audio Overviews.
Yes, in two ways. If your video is on YouTube (even unlisted), paste the URL directly into NotebookLM as a source. If it's a local video file, first transcribe it using a tool like Otter.ai, Descript, or Whisper, then paste or upload the transcript text into NotebookLM. I use this exact workflow for my course lesson recordings u2014 I run the transcript through NotebookLM and get a podcast-style summary my students can listen to while commuting. It's a fast way to make your video content accessible in a different format without re-recording anything.
The audio quality is clear and broadcast-ready u2014 there's no background noise, the pacing is natural, and the two-host format sounds genuinely conversational. Most listeners cannot immediately tell it's AI-generated. That said, if your brand requires a specific human voice or you have a strong personal presence your audience expects, NotebookLM audio won't replace a real recording. For repurposed content, supplementary episodes, or content summaries, the quality is absolutely publishable. Several of my students have launched entire Spotify podcasts using only NotebookLM-generated episodes.
ChatGPT will summarize or rewrite your document as text; NotebookLM generates an actual downloadable audio file with two hosts having a conversation. NotebookLM also stays strictly within your uploaded sources u2014 it doesn't pull in outside information or hallucinate context the way a general-purpose chatbot might. For audio content creation specifically, there's no direct equivalent at this quality level that's also free. Think of ChatGPT as a writing assistant and NotebookLM as a podcast production tool u2014 they serve different purposes.
