Opens a ChatGPT conversation straight from Chrome's address bar by typing a short keyword followed by your question.

What it does
Luna lets you start a ChatGPT conversation straight from Chrome's address bar by typing a short keyword and your question. It is for people who use ChatGPT often and want quicker ways to reach it while browsing.
Key features
- Starts a ChatGPT chat when you type "l" plus a query in the address bar
- Opens a new ChatGPT tab from anywhere with Ctrl+Shift+K or Cmd+Shift+K
- Sends highlighted text to ChatGPT from the right-click menu
Use cases
- Asking ChatGPT a quick question without opening its site first
- Getting an explanation of a confusing paragraph you just read
Getting started
Type l followed by a space and your question in the address bar, or highlight text and right-click to send it to ChatGPT.
Good to know
Luna itself needs no account, but it opens ChatGPT, so OpenAI's own sign-in and usage rules still apply.
