How It Works in 3 Simple Steps

From selection to understanding in seconds. Contextify integrates seamlessly into your browsing workflow.

1

Select & Activate

Highlight any text on any webpage. A small, unobtrusive Contextify icon will appear right beside your selection.

2

Choose Your Depth

Click the icon to open a compact popup. Choose a "Quick Explain" for a concise summary or preview the "Full Story" for a deeper dive.

3

Explore the Narrative

The "Full Story" opens in a dedicated page, complete with keyword extraction, image suggestions, and simple visualizations for a rich learning experience.

Powerful Features, Effortless Interface

Contextify is more than a translator; it's a complete sense-making tool powered by cutting-edge AI.

Dual-Mode Explanations

Not every query needs a novel. Get a lightning-fast summary for quick lookups, or a comprehensive 2-3 paragraph explanation when you need to truly understand a topic. The choice is yours, every time.

Rich "Full Story" Page

Go beyond plain text. Our full-page view renders longer narratives beautifully, automatically extracts key terms, and even suggests image queries to help you visualize complex subjects. It's your personal, on-demand research assistant.

Smart & Efficient

Our background service worker intelligently communicates with remote APIs, processes text, and manages state without slowing down your browser. Everything is optimized for a smooth and responsive experience.

Completely Open Source

We believe in transparency and community collaboration. Contextify is 100% open source. You can inspect the code, contribute to its development, and be part of its journey.
