Chie is a free and open-source cross-platform desktop application for Large Language Models (LLMs) like ChatGPT and Bing Chat. It has been developed in TypeScript and runs on a modified Node.js runtime with a native UI assisted by the Yue library. Chie runs on Windows, macOS and Linux and uses the native UI of the respective platform.

Presently, Chie officially supports the backend of three AI services as follows:

  1. Open AI API key
  2. ChatGPT web backend (requires you to sign in with an OpenAI account)
  3. Bing chat (requires login with a Microsoft account)

Additionally, Chie also allows you to use the backend of other AI services such as Google Bard using Chie extensions.


Apart from the standard and routine features, here are some unique highlights offered by Chie

  1. Multiple backends and multiple assistants: As stated above, Chie currently supports 3 AI services at the backend, but you can add more services using extensions. Chie also allows you to add multiple backends of the same type but with different credentials. This way, each backend can be configured with different parameters to create multiple AI assistants. For example, you can configure one assistant which will help you to edit emails while another to assist you in answering software development queries with the GPT-4 model.
  2. Extensions: Chie offers support for external extensions that are developed in JavaScript. Although there is no extension store but currently you can load them from your local disk. A few sample extensions have been offered free of cost such as chie-extension-browser-tools which can be used by AI assistants to browse and search the Internet, chie-extension-translator that implements translation assistants, along with a new TranslatorView and chie-extension-bard that add the Google Bard backend.
  3. Multiple windows: Chie allows you to open each AI assistant on a separate window. Alternatively, you can also group all assistant in the same default window.
  4. Multiple types of views: Chie offers 2 kinds of views: MultiChatsView that supports multiple conversations and simple ChatView that displays only one conversation and is very useful when users need some quick lookups. You can also add more view using Chie extensions. For example, the chie-translator-extension provides a TranslatorView that specially helps you in translation work.
