About Acumen: Context-First Summariser and Reading Tool
Acumen turns any webpage into something you can actually understand at a glance. Select text on a news article, research paper, legal document, or technical guide, and Acumen instantly gives you a context-aware AI summary plus vocabulary tooltips for unfamiliar terms — right where you're reading, with no tab-switching or copy-pasting into another app.
WHY ACUMEN
Most summarizers give you a generic TL;DR that ignores what the article is actually about. Acumen reads the surrounding context first, so its summaries and definitions are tailored to the specific piece you're reading — a legal clause is explained differently than a tech spec or a news paragraph.
KEY FEATURES
- Instant AI Summaries — Select any passage and get a clear, context-aware summary in seconds
- Smart Vocabulary Tooltips — Hover over unfamiliar words or jargon to get plain-language definitions without leaving the page
- Works Everywhere — News sites, academic papers, legal documents, and technical articles are all supported out of the box
- Lightweight & Fast — Built for speed so it never slows down your browsing
- Privacy-Conscious — Only the text you select is processed; Acumen doesn't track your browsing
WHO IT'S FOR
Students digesting dense academic papers, professionals parsing legal or technical documents, and everyday readers who want to understand the news faster — Acumen adapts to whatever you're reading.

1. Install the extension
2. Highlight any text on a webpage
3. Click the Acumen icon that appears
