Syntheo is a desktop app for Linux and Windows. It captures your microphone and your computer’s audio without joining the call as a bot. Each meeting becomes a living note: you prepare it, Syntheo listens, then it turns your notes into a summary (備 Prepare · 聴 Listen · 結 Synthesis). Why tea? Transcription and summaries go only through the servers you configure (vLLM, Ollama, speaches, NVIDIA NIM…). Syntheo has no account, no subscription, no telemetry, and never keeps the audio.

At a glance

  1. Configure your transcription server and your summary server in Settings → My servers (see Set up transcription and AI).
  2. On the home screen, click “Start a meeting”, then “Begin listening”.
  3. Take quick notes while Syntheo listens: the transcript scrolls in the margin.
  4. Click “Finish”: Syntheo writes the summary from the transcript and your notes.
  5. File the note in a folder to follow the project from one meeting to the next, and find it again with Ctrl + K, by its title or its content.
Your notes are stored locally, in a SQLite database on your computer. The audio lives in memory long enough to be sent to your transcription server, then disappears. See Data and privacy.
