CRUX: Enhance Your Web Reading Experience
CRUX is a browser extension that uses advanced AI to automatically extract, classify, and summarize online content into clear, structured highlights. Stay informed, streamline your research, and focus on what truly matters.
How It Works
Intelligent Content Extraction
CRUX scans webpages to extract meaningful text, ensuring you always get a coherent summary without unnecessary clutter.
Smart Classification
Using AI-driven text classification, CRUX identifies the type of content to tailor the summarization process specifically to the material at hand.
Tailored Summaries
The extension builds a structured prompt for the AI, resulting in a concise summary with clearly defined sections such as headlines, key points, quotes, and takeaways.
Interactive Overlay
The summarization is displayed in an unobtrusive, easy-to-use overlay on your current webpage, with intuitive controls for minimizing, copying, or retrieving full content.
Customization and Flexibility
User Control
Through the options page, you can enter your own OpenAI API key, manage usage limits, and set up URL exemptions—ensuring CRUX works exactly how you need it to.
Transparent Plans
You always know exactly how many summaries you have generated and how many more you can generate within the basic plan. We do not charge cancellation fees. You can seamlessly upgrade to a higher plan at any time.
Language
Choose your preferred language for summarization output, making content accessible and understandable in your native language.
Simplicity
Get started instantly - once signed up, the extension works automatically without any configuration needed, while still offering advanced customization options for power users.
