Overview

UniJump is a browser extension that brings ChatGPT access directly onto any webpage: a keyboard shortcut (Cmd+J) or widget opens quick chat access for summarizing text, rewriting or paraphrasing content, suggesting sentence completions, and changing languages, without navigating away from the current page.

Being open source, with the code publicly available on GitHub, and explicit that it stores no personal data, is a meaningful transparency choice for a browser extension that by nature sees whatever page a user is reading – anyone can verify the no-data-collection claim directly rather than trusting a privacy policy alone. Requiring only a free OpenAI account, with no separate UniJump registration, also keeps the setup friction minimal.

UniJump targets anyone wanting quick AI assistance while browsing, writers wanting in-context improvement suggestions, and privacy-conscious users. It’s completely free with no signup required beyond a free OpenAI account, currently available for Chrome only.
