Checkget is a browser extension that puts ChatGPT inside any website or web app, triggered by a Cmd/Alt+K keyboard shortcut so you can write, summarize, translate, fix grammar and explain code without copy-pasting between tabs.
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.
