Podcast post-production
What the AI that makes podcasts is called (and what it is really for)
Updated October 7, 2026
The best known is NotebookLM, by Google: you upload documents or links and it creates an audio conversation between two artificial voices, in many languages. There are others, such as ElevenLabs' GenFM feature or Wondercraft. They are useful for summarising and studying; for a podcast that builds a brand, the voice and the face have to be yours.
NotebookLM, the Google one
It is the one most people have in mind when they ask about the AI that makes podcasts. You upload notes, a PDF, a website or a video, and its audio overview feature generates a chat between two artificial hosts who explain the content in a very natural tone. It works in more than fifty languages and runs on a Google account. It is useful for reviewing a topic or getting through a long document while you drive.
Other AIs that generate podcasts
ElevenLabs, known for its synthetic voices, has a similar feature called GenFM that turns texts and links into a two-voice show. Wondercraft lets you build episodes with artificial voices, music and ads from a script. And some tools do not invent the podcast but help make it: cleaning up a voice, transcribing, creating captions or suggesting titles. They change fast, so test them with your own text before deciding.
What they are for, and what they are not
An AI-made podcast summarises what already exists well, but it does not bring what makes someone come back every week: a person with judgement, their experience, their opinions and the way they tell things. People follow people. If the goal is for your brand or company to build trust, artificial voices reading your documents will not get you there. For studying, internal use or testing an idea, they can work.
Where AI does help in a real podcast
In the part nobody sees. Transcribing the conversation to find the best moments, preparing captions, brainstorming titles or cleaning noisy audio are jobs where AI saves hours. What a person still decides is which moment deserves a clip, how it is cut so it has pace and which thumbnail makes someone click. That judgement is what separates a podcast that grows from one stuck at a hundred views. To see how to get the most out of each episode on social, read how to turn your podcast into clips.
If what you want is a brand podcast
Then AI is a tool for the team, not the show. At Bostak Films we produce video podcasts where the star is the person talking, and we use technology to get faster to what matters: good episodes, good clips and consistency. You can see how we work on our podcast production page or book the free podcast audit so we can look at your idea.
FAQ
What is the AI that makes podcasts called?
The best known is NotebookLM, by Google, which turns documents and links into a conversation between two artificial voices. Other options are ElevenLabs' GenFM and Wondercraft.
Can NotebookLM make podcasts in other languages?
Yes. Its audio overviews work in more than fifty languages, including Spanish. You choose the output language in the settings and it builds the conversation from whatever you upload.
Is an AI-made podcast good for my brand?
For internal use or to summarise content, it can work. To build trust with clients, no: people follow real people with their own judgement. What does work is using AI to speed up the production of a podcast made by people.
Will AI replace podcasts made by people?
It will fill the internet with automatic audio, and that makes human-made shows worth more. People who listen to a whole episode do it for whoever is speaking. AI changes how podcasts are produced, not why people listen.
