DeLive is a desktop transcription workspace for system audio. It captures whatever your computer is playing, routes the audio through any of fourteen 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, and every provider, cloud or local, can transcribe files.

🎯 Core Features

• System-audio capture — browser video, live streams, meetings, courses, podcasts, or any other playback source
• Fourteen ASR backends — Soniox, Volcengine, Groq, SiliconFlow, Mistral AI, Deepgram, AssemblyAI, ElevenLabs, Gladia, Cloudflare Workers AI, 60db, OpenAI-compatible local services, local FunASR / SenseVoice, and local whisper.cpp
• File transcription — upload audio/video files and transcribe them with any of the fourteen providers, including fully local whisper.cpp and FunASR / SenseVoice
• AI Review Desk — transcript correction (Quick Fix / Review & Fix), structured briefings, multi-thread chat, Q&A, and mind maps
• Floating caption overlay — always-on-top window with source / translated / dual display modes
• Soniox bilingual & speaker-aware — realtime translation, dual-line captions, speaker diarization
• Topics — organize sessions into project-like containers
• Local-first — sessions, tags, topics, and settings stored locally; optional S3/WebDAV cloud backup
• Open API & MCP — local REST API, real-time WebSocket, MCP server for AI agents
• Multilingual UI — English, Simplified Chinese, and Korean
• Cross-platform — Windows, macOS, and Linux
