Char transcribes and summarizes your meetings locally, keeping all data on your device with no bots joining your calls.
Char is a privacy-first, open-source AI notepad for meetings. It captures audio directly from your system instead of sending a bot into your calls. While you take notes, Char listens and transcribes everything in real time. After the meeting ends, it combines your notes with the transcript to produce a structured summary saved as plain markdown files on your device. You pick your AI stack: run fully offline with local models, bring your own API keys, or use Char's managed cloud. It works with Zoom, Teams, Google Meet, Slack, and in-person meetings.
Char is an open-source AI notepad for meetings. It transcribes your meetings in real time and generates structured summaries by combining your notes with the transcript. It runs locally on your device, keeping your data private.
Char captures audio directly from your system's microphone input and speaker output. It listens at the operating system level rather than joining your meeting as a participant. This means no bot appears in your call, and no meeting permissions are needed.
Char works with any application that produces audio on your computer, including Zoom, Microsoft Teams, Google Meet, Slack, and phone calls. It also works for in-person meetings by capturing microphone audio.
Yes. You can run Char fully offline by using local AI models through LM Studio or Ollama. Both speech-to-text and summarization happen on your machine with zero internet connection required.
Char supports 90+ languages for transcription, including English, Spanish, French, German, Japanese, Korean, Chinese, and many more.
All notes, transcripts, and summaries are saved as plain markdown files on your local filesystem. You can open them with any text editor, Obsidian, Notion, or VS Code. Char never stores your data on its servers unless you opt into cloud features.
Char currently supports macOS (both Apple Silicon and Intel). Linux support is available via AppImage and .deb packages. Windows and iOS versions are in development.
