DeLive is a desktop transcription workspace for system audio. It captures whatever your computer is playing, routes the audio through any of twelve ASR backends, keeps everything on your machine, and turns completed transcripts into searchable history with a full AI Review Desk — AI transcript correction, rich Markdown-rendered chat, Q&A threads, structured briefings, and mind maps. It also supports uploading audio/video files for offline transcription, with ten cloud engines available for file transcription.

⚠️ Notes

• System requirements: Windows 10+, macOS 13+, or Linux with PulseAudio loopback support.
• Provider proxies are embedded in Electron — no separate backend needed for desktop usage.
• Tray behavior: closing the main window hides to tray instead of exiting.
• Auto-update: supported on Windows, macOS, and Linux AppImage.

🛡️ Windows SmartScreen Warning

Windows may show a SmartScreen warning on first launch. Click More info → Run anyway.
