Key Takeaways
- AI podcast tools make it easy to repurpose written content, helping you reach audiences who prefer listening over reading, ideal for busy, on-the-go listeners.
- Wondercraft AI, Google NotebookLM, and Podcastle lead the 2025 lineup, each with their unique strengths: advanced editing, natural conversational audio, and all-in-one production tools.
- Converting articles into podcasts expands your visibility across major platforms like Spotify, YouTube, and Apple Podcasts, turning one piece of content into multiple traffic sources.
- While these AI tools help you convert one article into one podcast, AmpiFire’s AmpCast automatically transforms your content into seven different formats (including podcasts) and distributes everything across 300+ platforms, turning hours of manual work into a single automated process.
Why Convert Articles to Podcasts
Reach Audio-First Audiences
Not everyone likes reading. Some people would rather listen while they drive, exercise, or do chores. When you turn your articles into podcasts, you reach these audio-first audiences who might never visit your website.
Your article might get a few hundred readers. But that same content as a podcast could reach thousands more people who prefer listening over reading.
Repurpose Existing Content Easily
You already spent time writing great articles. Why not get more value from that work? Converting articles to podcasts means you’re creating two pieces of content from one effort.
The same article can live as a blog post on your website and as a podcast episode on Spotify, Apple Podcasts, and YouTube. Double the reach with minimal extra work.
Make Content Accessible On-the-Go
Reading requires your full attention and both hands. Listening doesn’t. People can consume podcast content while commuting, working out, cooking dinner, or walking the dog.
By offering your content as audio, you make it available during times when reading isn’t possible. This convenience means more people actually consume your content instead of bookmarking it for later and forgetting about it.

Best Article-to-Podcast AI Tools
1. Wondercraft AI
What It Does
Wondercraft is a complete AI audio studio that turns your written content into professional podcasts with realistic voices, background music, and sound effects. You can create podcasts from articles, blog posts, PDFs, or even just ideas.
Best For
Content creators and businesses who want full creative control over their podcast’s sound. If you care about voice customization, music mixing, and professional production quality, Wondercraft gives you studio-level results.
Key Features
Wondercraft stands out with its voice customization options. You can edit existing AI voices to adjust accent, tone, and emotion. Or describe the exact voice you want, and Wondercraft generates it for you.
The platform includes Director Mode, which lets you control exactly how each line should sound. You can also use Parrot Mode; speak your line out loud, and the AI voice will match your delivery.
Alongside voices, Wondercraft has a full timeline editor where you drag and drop voice clips, music, and sound effects. The platform gives you access to royalty-free music and an AI sound effects generator.
Wondercraft supports content creation in over thirty languages, making it easy to reach global audiences.
How It Works
Start by uploading your article, PDF, or notes to Wondercraft. You can also just describe what you want in a prompt. The AI generates a script based on your content.
Choose from thousands of AI voices or create a custom voice. Use the timeline editor to arrange your audio, add music, and include sound effects. When you’re happy with the result, export your podcast as an audio file.
Wondercraft offers a free starter plan with six credits per month (six minutes of audio generation). Paid plans provide more credits and advanced features.
2. Google NotebookLM
What It Does
NotebookLM is Google’s free AI research assistant that can turn your documents into podcast-style audio conversations. Two AI hosts discuss your content in a natural, conversational format called Audio Overviews.
Best For
Students, researchers, and educators who want to transform dense documents or research papers into easy-to-understand audio summaries. NotebookLM excels at making complex information accessible.
Key Features
NotebookLM creates engaging conversations between two AI hosts who discuss your content. These Audio Overviews sound remarkably natural, with hosts asking each other questions and building on each other’s points.
You can upload PDFs, Google Docs, websites, YouTube videos (with transcripts), and Google Slides. NotebookLM analyzes all your sources together and creates a cohesive audio discussion.
The tool includes automatic transcription in multiple languages and generates study guides, summaries, and FAQs from your sources. Everything NotebookLM creates is grounded in your uploaded content; it doesn’t pull information from elsewhere on the internet.
NotebookLM is completely free for personal Google accounts, with a Plus version available for power users who need higher limits.
How It Works
Create a notebook in NotebookLM and upload your sources: articles, documents, or links. Once your sources are uploaded, click the Audio Overview button.
NotebookLM generates a podcast-style conversation discussing your content. The two AI hosts will naturally explain key concepts, highlight important points, and make your material easier to understand.
You can listen directly in NotebookLM or download the audio file. The tool automatically provides timestamps, and you can review the transcript alongside the audio.
3. Podcastle
What It Does
Podcastle is an all-in-one podcasting platform that includes text-to-speech capabilities alongside traditional recording and editing tools. You can create podcasts entirely with AI voices or mix AI-generated audio with your own recordings.
Best For
Podcasters who want flexibility. If you sometimes want to record yourself and other times use AI voices, Podcastle handles both seamlessly in one platform.
Key Features
Podcastle’s text-to-speech feature lets you type your article and have realistic AI voices read it. You can choose from different AI voices and adjust the delivery style.
The platform includes professional audio editing tools like Magic Dust, which removes background noise with one click, and automatic filler word removal that cuts out “umms” and “ahhs.”
Podcastle offers remote recording, letting you interview guests from anywhere with studio-quality sound. The platform also provides video recording and editing if you want to create video podcasts.
Text-based editing is available, so you can edit your podcast by editing the transcript, and the audio changes automatically. Podcastle also handles transcription and can generate captions for video content.
How It Works
Sign up for Podcastle and create a new project. Choose if you want to use text-to-speech, record yourself, or combine both approaches.
For text-to-speech, paste your article into Podcastle and select an AI voice. The platform generates the audio. You can then edit using Podcastle’s audio tools, like trim sections, remove background noise, add music, or adjust volume levels.
When finished, export your podcast or use Podcastle’s built-in hosting to publish directly to major podcast platforms.
Podcastle offers a free plan with limited features and paid plans for creators who need more recording time and advanced tools.
How to Choose the Right Tool for You
Consider Your Budget
NotebookLM is completely free, making it perfect if you’re just starting or want to test the waters. Wondercraft, and Podcastle all offer free plans with limited features, so you can try before committing to paid options.
If you need professional features regularly, compare the paid plans. Think about how many minutes of audio you’ll create each month and what features matter most to you.
Think About Customization Needs
If voice quality and customization are priorities, Wondercraft offers the most control with Director Mode and custom voice creation. For straightforward conversions without much tweaking, NotebookLM and Podcastle work well with minimal setup.
Look at Distribution Options
Wondercraft and NotebookLM focus on creating the audio; you’ll need to handle distribution separately or use a podcast hosting service. Meanwhile, Podcastle includes hosting and distribution features.
Scale Your Content Distribution with AmpiFire
Turning your articles into podcasts is great, but what if you could automate everything about content repurposing?
That’s exactly what AmpiFire’s AmpCast platform does. It takes your original piece and automatically converts it into seven optimized formats, including podcasts. You don’t just get an audio version; you also get blog posts, news articles, social media snippets, slideshows, infographics, and short videos, each fine-tuned for different platforms.
Then comes the best part: AmpCast distributes everything across a network of 300+ top-tier platforms. Your content lands on major news sites, podcast directories, and social channels, all without you lifting a finger.
Forget juggling multiple tools or spending hours republishing your work. With AmpCast, you write once, and your content goes everywhere, automatically.
Frequently Asked Questions (FAQ)
Do I need any recording equipment to use these tools?
No recording equipment needed. All four tools create podcasts using AI voices, so you never touch a microphone. Just provide your written content and the AI generates the audio. Podcastle does offer recording features if you want to use your own voice, but it’s completely optional.
Can I edit the podcast after the AI creates it?
Yes. Wondercraft and Podcastle all include editing tools. You can adjust the script, change voice delivery, add music, or trim sections. NotebookLM doesn’t offer editing; what it generates is final, but you can create multiple versions from the same sources.
How long does it take to create a podcast from an article?
Very fast. NotebookLM generates Audio Overviews in just a few minutes. Wondercraft and Podcastle also work quickly; expect anywhere from five to fifteen minutes, depending on your article length and how much customization you want. The actual AI generation happens in minutes; most time goes into reviewing and tweaking the result.
How does AmpiFire’s automated podcast creation compare to using these individual tools?
Individual tools require you to manually upload your article, generate the podcast, edit it, and then distribute it yourself to each platform. AmpiFire’s AmpCast automates this entire workflow; it takes your content and creates podcast episodes along with six other content formats, then automatically distributes everything across hundreds of platforms simultaneously. Instead of spending several hours converting and distributing one article across multiple tools and platforms, AmpCast does it all in minutes while you focus on creating more content.
