OpenWispr

OpenWispr is an open-source application that provides voice-to-text dictation and AI assistance. It operates as a desktop application for macOS, Windows, and Linux, allowing users to convert speech into text, notes, and actions directly at the system cursor via global hotkeys. The software is designed to replace manual typing with voice commands across any installed application.

The software supports both local and cloud-based processing to accommodate different privacy and performance needs. Users can choose offline transcription to keep audio entirely on their device or utilize cloud providers for increased speed. It includes specialized tools for meeting transcription, speaker identification, and a comprehensive system for organizing AI-generated notes and transcripts.

Key features

• Global hotkey for dictation with automatic pasting into any active application
• Local transcription using Whisper and NVIDIA Parakeet engines
• AI agent integration with support for GPT, Claude, Gemini, Groq, and local models
• Meeting transcription with live speaker diarization and voice fingerprinting
• Google Calendar integration for automatic meeting detection
• Note management system with folders and semantic search
• Public API and MCP server for programmatic management of notes and transcripts
• Cross-platform support via Electron for macOS, Windows, and Linux

Built with React 19, TypeScript, and Electron, the application uses whisper.cpp and sherpa-onnx for high-performance local inference. It is designed for users who require privacy-first dictation and those who want to integrate voice commands with large language models without relying on a single proprietary ecosystem. The architecture allows for a flexible choice between on-device processing and cloud APIs for reasoning and transcription, ensuring that sensitive audio data does not have to leave the local machine. For those using the cloud version, Neon provides the serverless Postgres infrastructure.

OpenWispr is a privacy-centric utility for voice-driven productivity and automated meeting documentation.
