Prismical

Prismical is a free, open-source AI note-taking companion that captures meetings, lectures, and voice notes with complete privacy. Unlike traditional meeting recorders, it works silently through your system audio—no bot joins your calls, and no one knows you're recording.

Key capabilities include:

• Real-time transcription with speaker identification using local AI models (Whisper, Parakeet) or cloud providers of your choice
• Automatic summaries and action items that extract key decisions and follow-ups from meetings
• Voice notes and brain dumps that get automatically structured and formatted
• AI integrations via MCP server, allowing Claude, ChatGPT, Gemini, and other assistants to read and write your notes
• Works everywhere by capturing system audio from any app—Zoom, Meet, Teams, Slack, WebEx, or anything that plays audio
• Floating window for always-on-top transcripts and action items without switching apps

Privacy is built in. Audio stays on your machine by default with local AI processing. If you choose cloud transcription, you bring your own API keys. The entire codebase is open source and MIT licensed on GitHub with no hidden data collection.

Available as native apps for Mac and Windows, with iOS and Android coming soon. Perfect for teams, students, doctors, lawyers, journalists, creators, and anyone who needs to capture and organize information from conversations.
