Video jargon explainer
Understand the specialist language that carries the idea
Expert speakers often use domain vocabulary without stopping to define it. JargonLens supplies a short explanation at the point where context is strongest, helping you understand the argument rather than merely recognize the words.
AI video glossary
Keep the important terms from each video together
The extension creates a searchable glossary for the current video. Each entry includes the term, a concise definition, its subject area, and the relevant timestamp so you can return to the original explanation.
You can mark familiar terminology as known, adjust how many definitions appear, and clear recent glossaries from the extension.
