OpenAI Chat

PopClip extension to send the selected text to OpenAI's GPT-3.5, GPT-4, GPT-4-Turbo or newest GPT-4o Chat API.

The response is pasted after the selected text. The previous messages in the chat are sent along with each new message, allowing an extended dialogue with the AI.

Note: Requires pre-paid API credits on your OpenAI account. API usage is not included in ChatGPT Plus subscripiton.

See also: ChatGPT Website extension, which opens a new chat on the ChatGPT website.


The main action, Chat, sends the selected text to OpenAI and appends the response as a new line.


  • Hold Shift(⇧) to copy just the response to the clipboard.

  • Hold Option(⌥)-Shift(⇧) to paste just the response over the selection.

The Reset action (broom icon) clears the current chat history to start a fresh conversation.

System Message

Optional text to specify the system message. This tells the chatbot how to behave.

Example system message:

  • You are proofreader. I want you to correct the spelling and grammar of my messages. Please reply to each message with a corrected version. After each message, please briely list the errors you corrected.

If you leave the System Message field blank, no system message will be specified.

Reset Timer (minutes)

After this many minutes without any messages, the extension will automatically reset the conversation. Set it blank to never reset, and set it to 0 to always reset. The default value is 15 minutes.
