What is it?

Prismical is an open-source AI note taker for macOS and Windows that transcribes meetings, lectures and voice notes. It captures system audio in the background, so no bot needs to join the call, and works with apps such as Zoom, Google Meet, Microsoft Teams, Slack and WebEx.

Transcription can run on-device with whisper.cpp, or go through cloud or local models: OpenAI, Anthropic, OpenRouter, any OpenAI-compatible endpoint, or Ollama. The AI turns transcripts into structured notes with key decisions and action items, and includes built-in skills such as Enhance, Cleanup and Ask, plus custom skills.

The desktop app is built with Electron, React and TypeScript, with SQLite storage and full-text search across meetings and notes. An optional Prismical cloud adds cross-device sync, sharing and calendar features, and iOS and Android apps are available separately.
