Show HN: Open-source API alternative to NotebookLM

Could we replicate the NotebookLM's podcast feature as a customizable API?

Live demo: https://huggingface.co/spaces/thatupiso/Podcastfy.ai_demo Open Source Python package: https://github.com/souzatharsis/podcastfy

Apache-2.0 license

Key Features: - Generates conversational content from multiple sources (e.g. URLs, YouTube, and PDFs) and modalities (images+text) - Customizes transcript and audio generation (e.g., style, language, structure, length) - Provides multi-language support for global content creation

Technical Highlights: - Flexible LLM integration with LangChain, supporting both cloud-based and local models - Support for advanced text-to-speech models (OpenAI, ElevenLabs, and Microsoft Edge) - Seamless CLI and Python package integration for automated workflows

NotebookLM's AI-generated voices remain unparalleled in quality (SoundStorm is awesome!). We would love additional contributors to help build this open source alternative!

Thanks. The webapp is new and hopefully with make it easier for users to try it out and share feedback so we can improve the underlying package.

Would love your feedback!
