LookStuffUp

Tired of opening a new tab for every little question? LookStuffUp is a lightweight Chrome extension that gives you instant answers, summaries, and translations right where you are, keeping you in the flow.

Why it's different:

LookStuffUp was built to be the tool I always wanted. It's 100% free, with no ads, no sign-ups, and no paywalls. It's also completely private—I don't track or collect any of your data.

Key Features:

💡 Instant Context: Highlight any word or phrase to get a concise definition or summary from multiple sources, including Wikipedia, Wiktionary, and the dictionary.

🤖 On-Device AI: Use Chrome's built-in AI to summarize long articles or translate text between 20 different languages, all on your device. This means it's private and works offline!

🎨 Customizable: Make it your own! You can drag the lookup window anywhere, switch to dark mode, adjust the font size, and even set a custom background color.

🌎 Multi-Language Ready: The extension automatically detects the language of the highlighted text and provides results from the appropriate sources.

? Lightweight and Fast: A smart cache gives you near-instant results for recent searches, and the extension is optimized to be light on your computer's resources.

🔒 Privacy First: Your privacy is a top priority. There are no ads, no analytics, and no tracking. Your lookup history and API key (if you choose to add one) are stored locally on your device.

Who is it for?

LookStuffUp is perfect for students, researchers, writers, and anyone who wants to be more productive and stay focused while browsing the web.

Notes:

Currently available for desktop versions of Chrome. This extension is completely free, with no upsells or hidden costs.
