Casper AI is a Chrome extension for copywriting and research workflows that summarizes web pages and PDFs so you can brief articles, track policy changes, or scan deal documents without reading every word. It runs inside the browser, pulls text from the page you are on, and turns long sources into short notes you can share with teammates.

Where many sidebar assistants chase open-ended chat, Casper AI stays closer to analyst-style reading work. It highlights new insights from public sources, compresses news into shareable summaries, and focuses on understanding and distributing findings rather than generating full drafts from scratch. That narrow scope suits professionals who need quick comprehension more than long-form content generation.

The Chrome Web Store listing targets analysts, strategists, policymakers, and business developers who prepare for exams, research investments, work on deals, or track new laws. Version 0.4.2 lists about 10,000 users and a 4.4 out of 5 rating from 77 reviews, with English as the only supported language.
