Next Steps

Looking ahead, there are two promising directions for expanding the YouTube Chapter Generator:

  1. Open-Source Version
    • Allow users to choose their own ASR system for transcription (AWS Transcribe, Whisper, etc.).
    • Let them pair that with their preferred LLM (Gemini, OpenAI, local models, etc.) for chapter generation.
    • Distribute with simple CLI or Docker setup so it's easy to run locally.
  2. Native macOS App
    • Build a desktop app that runs the two-step process (ASR → LLM) directly on the machine.
    • Integrate chapter generation into the YouTube upload workflow, so chapters attach automatically.
    • Simplify the publishing process for creators who upload frequently from their Macs.
