Show HN: Use your OpenAI subscription to create audiobooks

A new tool allows users to convert PDFs into audiobooks using their existing OpenAI or Google API subscriptions, with document processing covered by the subscription and speech generation billed separately by usage. The process involves connecting an AI service like OpenAI or Anthropic's Claude through a plugin, adding a speech API key, and then uploading a PDF to generate audio content. The service aims to provide a low-cost way to create audiobooks by leveraging subscriptions users already pay for.
