Introducing AI Podcasts: Transform Your Documents into Dynamic Conversations

The Future of Content Consumption is Here

We're thrilled to announce the launch of our most requested feature: AI-Powered Podcast Generation. With this groundbreaking addition to Synthema, you can now transform any document—whether it's a research paper, study guide, or business report—into a natural, engaging conversation between AI speakers.

Gone are the days of struggling through dense text or boring presentations. Our AI doesn't just read your content; it creates dynamic discussions that make complex topics accessible and entertaining.

What Makes Our Podcast Feature Special?

Multiple AI Speakers

Choose between 1-2 speakers to create natural conversations. Each speaker has distinct characteristics and can take on different perspectives, making your content more engaging than traditional text-to-speech.

30+ Professional Voices

Select from an extensive library of voices including Zephyr (bright, higher pitch), Puck (upbeat, middle pitch), Charon (informative, lower pitch), and 27 more options. Each voice has unique characteristics to match your content's tone.

Universal Document Support

Works with PDFs, Word documents, text files, Markdown, images, and even YouTube videos. Our AI extracts and processes content from virtually any source material.

Customizable Tone

Choose from conversational, professional, warm, educational, or casual tones to match your audience and content style.

How It Works

Creating an AI podcast is incredibly simple:

1. Upload Your Content: Add any document to your Synthema space - PDFs, Word docs, images, or even YouTube video links.
2. Configure Your Podcast: Choose your title, number of speakers, voices, and conversation tone. Our intuitive interface makes customization effortless.
3. AI Magic Happens: Our advanced AI (powered by OpenAI GPT-4o) analyzes your content and creates a natural conversation script, then Google's Gemini TTS generates professional-quality audio.
4. Listen & Share: Your podcast is ready! Stream it directly in Synthema with our built-in player, or download the high-quality WAV file.

Built for Excellence

Behind the scenes, our podcast feature represents a significant technical achievement:

• Advanced Audio Processing: Each podcast is generated as a high-quality WAV file with proper audio metadata and duration tracking
• Smart Content Analysis: Our AI understands context, extracts key points, and creates natural conversation flow
• Seamless Authentication: Secure audio streaming with token-based authentication ensures your content stays private
• Memory Management: Optimized audio players with proper cleanup prevent memory leaks during long listening sessions

Professional Audio Player

We've built a sophisticated audio player that rivals dedicated podcast apps:

• Background audio support for multitasking
• Automatic metadata loading for instant duration display
• Smart memory management for multiple podcast players

How Synthema compares to other podcast tools

Many apps can read text aloud, but Synthema creates actual conversations. Traditional text-to-speech is monotone and boring. AI voice cloners require complex setup. Podcast creation tools are manual and time-consuming. Synthema combines intelligent script generation, natural conversations, and professional audio into one easy-to-use platform.
