Jargon Vault Extension

Jargon Vault is a powerful yet lightweight browser extension that helps you instantly understand acronyms, abbreviations, and jargon as you browse the web. In today’s world, many fields use the same terms with entirely different meanings depending on the context — leading to confusion, misinterpretation, and constant context-switching just to figure out what a term actually means. Whether you're reading technical documentation, navigating internal tools, or reviewing content packed with industry-specific language, Jargon Vault highlights unfamiliar terms directly on the page and displays their definitions with a single click — no need to switch tabs to search on Google, scroll back up the page to find a glossary, or ask ChatGPT (which can give you the wrong result if not provided with the right context).

Designed for students, professionals, and cross-functional teams working in tech, finance, healthcare, law, and beyond, Jargon Vault brings clarity by surfacing the right meaning based on your field. It comes equipped with curated public “vaults” organized by industry or field, and users can also search for jargon directly from the extension popup — exploring terms by category or niche on demand.

🔑 Key Features

🖊️ Highlight and expands acronyms, abbreviations, and jargon terms on webpages and display full definitions on click.
🔎Browse curated public vaults organized by industry or topic to quickly find relevant jargon definitions.
🌐Customize which websites Jargon Vault scans using flexible include and exclude URL rules.
