What Hacker News says
2 sourcesShow HN: Topcast – Open-Source Alternative to Google NotebookLM Podcast Feature
Google recently introduced a feature in NotebookLM that generates podcast-like audio from documents using AI. I’ve developed an open-source alternative called Topcast. It provides similar functionality but offers full control and customization.
Topcast is a Python package that converts text into audio using Text-to-Speech (TTS) and AI-generated themes like interviews and summaries. You can layer audio tracks, add background sounds, and integrate various TTS providers (Google Cloud, Elevenlabs, or Google Translate).
Key Features:
• Fully open-source and customizable
• Support for multiple TTS providers
• AI-generated content structures (e.g., interviews, summaries)
• Flexible audio layering with fades and crossfades
Usage:
1. Input your text.
2. Select a TTS provider and an AI theme.
3. Generate audio with a few lines of code.
4. Exp

ort the result to an audio file.
