OpenWhispr

The open-source and free alternative to WisprFlow and Granola.

Privacy-first voice-to-text dictation with AI agents, meeting transcription, and notes. Cross-platform for macOS, Windows, and Linux.

Website · Docs · Download · API · Changelog

OpenWhispr turns your voice into text, notes, and actions from your desktop. Press a hotkey, speak, and your words appear at your cursor. Choose between fully private offline transcription with local speech-to-text engines like Whisper and NVIDIA Parakeet — where your audio never leaves your device — or cloud processing for speed. No data collection, no telemetry, fully open source.

Features

• Voice dictation — global hotkey to dictate into any app with automatic pasting
• AI agent — talk to GPT-5, Claude, Gemini, Groq, or local models with a named voice assistant
• Voice agent hotkey — dedicated hotkey that sends your dictation straight to your AI agent as a command, no wake word needed and no cleanup pass
• Meeting transcription — auto-detect Zoom, Teams, and FaceTime calls with live speaker diarization, voice fingerprinting, and Google Calendar integration
• Local speaker diarization — on-device speaker labelling with voice fingerprint recognition across meetings, no cloud required
• Notes — create, organize, and search notes with folders, semantic search, cloud sync, and AI actions
• Local or cloud — your choice — all core features (transcription, AI reasoning, speaker diarization, semantic search) work with local models or cloud providers
• Public API & MCP — manage notes and transcriptions programmatically or connect your AI assistant via the MCP server
