About Use your OpenAI subscription to create audiobooks
Key Strengths
- Connects to Codex or Claude over MCP, so your existing AI subscription handles document processing
- Exports a full MP3 plus one per chapter, with iPhone and Android apps for listening
- Can narrate in a different language than the source, with 11 languages supported
Limitations to Consider
- Despite the name, you still need an OpenAI or Gemini API key for speech, billed per use; Hacker News commenters called the title misleading
- Asks you to paste an API key into the site, which several HN commenters warned against unless it has a spend cap
- One tester on HN said the word highlighting drifted out of sync with the audio, and the maker said tables haven't been tested much
Best For
People with a Codex or Claude subscription who want to listen to papers and long PDFs on the go.
Skip it if: You don't want to hand an API key to a third party; local, offline audiobook generators exist.
