pricing

Open Notebook Pricing & Plans

Open Notebook operates on a freemium model, with its core software being open-source under the MIT license. Users can self-host the platform at no direct software cost, leveraging their own infrastructure and chosen AI provider APIs. The 'freemium' aspect typically refers to potential future premium features, hosted services, or enterprise support offerings that may be introduced by the developer or third parties. The primary cost for users comes from the consumption of external AI provider APIs (e.g., Mistral, Deepgram, Google, ElevenLabs) or the hardware required to run local LLMs via platforms like Ollama.

  • 1Open-source core: Free (self-hosted)
  • 2API usage: Variable, based on chosen AI provider rates
  • 3Local LLM usage: Free (requires user-provided hardware)
