UniJump

UniJump is a browser extension that gives you quick access to ChatGPT from any website you're browsing. Instead of switching tabs or windows to open ChatGPT, you can summon it with a keyboard shortcut or a widget right where you are. The extension is free, open source, and requires no signup — you just need an OpenAI account.

The extension works with a simple shortcut (⌘ Cmd + J on Mac) or by clicking the UniJump widget. It includes a Paraphraser tool and a Quick Chat feature, so you can rewrite sentences, ask questions, or get writing suggestions without leaving the page. UniJump is fully open source on GitHub, and the developers emphasize transparency — they don't store any of your personal data, browsing history, or inputs. You can verify this by reviewing the code yourself.

UniJump is ideal for anyone who uses ChatGPT frequently throughout the day — writers, students, researchers, or professionals who want to improve their writing or get quick answers without context switching. It's especially handy for tasks like paraphrasing a sentence, brainstorming ideas, or summarizing text while reading an article. Since it's free and doesn't require an account, it's a low-friction way to integrate ChatGPT into your daily browsing.
