ChatGPT on any website with a single Cmd/Alt+K shortcut
Press Cmd+K on macOS or Alt+K on Windows to summon the assistant on virtually any site or compatible desktop app, with no copy-pasting into a separate chat window.
The extension detects context automatically, so selecting an email and pressing the shortcut offers a reply-style action, while selecting code offers explanation or optimization actions.
Summarize pages, translate text, correct spelling and grammar, expand or shorten passages, rephrase sentences and switch tone of voice from a quick menu.
Dedicated actions for explaining snippets and optimizing code, useful for developers reading unfamiliar source in a browser.

Select any text in an app, email or message and correct all grammar and spelling errors in one tap instead of reviewing word by word.

Sliders and filters adjust formality, friendliness, length, rephrasing and emoji so output matches your personal voice.
