Acumen: Context-First Summariser and Reading Tool

Instant context-aware AI summaries and vocabulary tooltips for selected text. Works on news, academic, legal, and tech articles.

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.
