ChatGPT Extension is a free Chrome add-on developed by chensihai that allows users to enhance their ChatGPT experience. With this flexible extension, users can easily send selected text to the ChatGPT API for processing.

To get started, simply highlight the text you want to process with ChatGPT on any Chrome or Edge webpage. Then, click on the Taichi (black/white) logo located to the right of the browser's address bar. Choose a prompt from the options and click "Submit."

One of the key features of this extension is the ability to customize prompts. In the extension options, users can add custom prompts, each on a separate line. This allows for a variety of interactions with ChatGPT, such as friendly chats, translations between Chinese and English, content summarization, providing more detailed information, assisting in writing response emails, and even displaying images.

It's worth noting that while the extension interface is available only in English, users can write prompts in other languages, although the ":" symbol must be in English.

With ChatGPT Extension, users can easily leverage the power of ChatGPT API to enhance their browsing experience and make interactions with ChatGPT more seamless.
