KohAI third party notices
Last updated: 4 October 2026
KohAI is closed source, made by its founders. It includes the open source software below. Each part stays under its own licence, and nothing in the KohAI terms limits your rights under those licences. The full licence texts are in the KohAI install folder and in the app under Settings, Open source licences.
KohAI has no runtime npm packages. The app uses the fonts already on your computer and ships no font files.

Mac build: whisper-cli is built from the same whisper.cpp source commit, MIT only, linked to Apple's own Accelerate framework.
FFmpeg notice
KohAI uses libraries from the FFmpeg project under the LGPLv2.1. FFmpeg is a trademark of Fabrice Bellard. The library is the file ffmpeg.dll (Windows) that comes with Electron; KohAI does not change it, and you may replace it with your own build. The source of this copy is at chromium.googlesource.com/chromium/third_party/ffmpeg, and Electron's build of it is published with each Electron release at github.com/electron/electron/releases/tag/v44.5.1. The text of the LGPL 2.1 is at gnu.org/licenses/old-licenses/lgpl-2.1.html.
MPL 2.0 notice (Pyodide, hiwire)

Not part of KohAI
The AI tools KohAI starts (Claude Code by Anthropic, Codex by OpenAI, Gemini CLI by Google) are installed by you, separately, and come under their makers' own licences and terms. KohAI does not include or distribute them.
The build tools (electron-builder and its download chain) are used only to make the installer and are not inside the app, apart from the installer parts listed above.
