Tired of breaking your focus by opening a new tab for every little thing you need to look up? Me too.
That's why I built LookStuffUp, a powerful and 100% free extension that puts knowledge right at your fingertips.
My philosophy is simple: this is a tool I wanted for myself, and I'm sharing it FOR FREE. No ads✅, no in-app purchases✅, no paywalls✅. All the features you see are yours to use, right out of the box.
Key Features 🚀
-💡Instant Context, Anywhere: Just highlight any word or phrase. A clean, non-intrusive tooltip instantly appears with the information you need. Click the source link to dive deeper.
-🧠Intelligent & Multi-Source Search: I've designed the search to be smart. It understands variations in text (like "Da Vinci's") and pulls the best information from multiple sources like Wikipedia, Wiktionary, and the dictionary to give you a well-rounded definition or summary.
-🤖On-Device AI for Summaries & Translation: Go beyond simple lookups. With Chrome's experimental AI features enabled, you can instantly summarize long articles or translate text between 20 languages. Because this all happens on your device, it's completely private and even works offline!
- 🎨Fully Customizable Experience: Make the tooltip your own:
-🖐️Drag it anywhere on the screen.
-🌙Toggle Dark Mode.
- Adjust the font size.
- Set a custom background color (the text color adjusts automatically for readability!).
-⛔Blacklist websites where you don't want the extension to run.
- 🌎Multi-Language Ready: The extension automatically detects the language of the text you highlight and provides results from the appropriate sources.
-⚡Performance-Optimized: A smart cache provides near-instant results for recent searches, and the extension is designed to be lightweight, saving you RAM compared to opening a new tab for every query.
- Google-Powered (Optional): For power users, you can add your own free Google API key to get the highest quality results, using the full power of Google Search without leaving your current page.
Your Privacy Comes First 🔒
I don't collect any of your data. Period. Your API keys are stored securely in your browser, your lookup history stays on your computer, and the AI features run locally. Your business is your own ;)
