Highlight any text on a news article for instant historical context, implications, and related reading. Preface — context for every headline, term, and ticker. News moves fast and assumes you already know the backstory. A term you've heard but can't define, an executive you don't recognize, a deal referenced like it's common knowledge, a ticker symbol buried in a sentence — Preface fills that gap instantly, without leaving the article. Built for finance students, market watchers, and anyone trying to actually understand what they're reading, not just skim past it. Highlight any text in a news article, and Preface shows you: Historical Context — Why it matters to this story Implications — What it means going forward Connections — Forces driving the story, in the article, and the bigger picture Market Data — Live prices and context for companies and financial terms Further Reading — Real articles to go deeper Why install it: Built for financial literacy, not generic lookups. Preface doesn't just define a term — it explains why it's in this article, right now. No new tabs, no breaking your reading flow. Context appears right where you're already reading. Fast. Return in seconds — keep up with the pace of the news cycle. Private by design. Preface only ever sends the text you highlight and the page's title — never your browsing history, never the full article, never anything else on the page. Stop pausing mid-article to Google a term or look up a ticker. Highlight, understand, keep reading.
