Unpack

Unpack adds clear, precise inline annotations to any text you select (or to the whole page). Whether you're reading a research paper, a financial report, or a classic novel, Jargon surfaces what terms mean, where they come from, and what they reference. Five annotation types: • Definitions — technical and domain-specific terms explained in plain language • Etymology — word origins and how meanings have evolved over time • References — cultural, literary, and historical allusions unpacked Three detail levels: • Simple — plain language, short sentences, everyday analogies • Standard — clear and precise, aimed at an educated non-specialist • Expert — dense, rigorous definitions with formal notation and canonical references Language support: Annotate in English, French, Spanish, German, Italian, Portuguese, Dutch, Polish, Russian, Chinese, Japanese, Arabic — or let the extension auto-detect the language of the page. How it works: 1. Choose annotation type(s), detail level, and language 2. Select text on any webpage and click the tooltip — or click Annotate to process the whole page 3. Annotations appear inline, right where you need them Privacy: Selected text is sent to our API solely to generate annotations. It is never stored, logged, or linked to your identity. See our privacy policy for full details. Free tier: 10 annotations per day — no sign-up required. Pro: Unlimited annotations for $1/month via Stripe. Built by More & Different.
