JargonLens: YouTube Jargon Explainer

Understand technical, financial, and industry terms in YouTube videos with timely, plain-English definitions.

JargonLens is a YouTube jargon explainer that identifies technical, financial, business, and industry terms in captioned videos and shows plain-English definitions when they are spoken. Stay focused on the video instead of opening new tabs every time a speaker uses unfamiliar terminology. Features: • Timely definition overlays appear about one second before a term is spoken. • Click an overlay to pause its timer; click again to continue. • Double-click a definition to request a longer plain-English explanation. • Open a searchable glossary containing terms for the current video only. • Click a glossary term to jump to the exact moment it appears. • Choose whether repeated terms appear once or again when occurrences are at least 30 seconds apart. • Mark familiar terms as known so JargonLens stops showing them. • Revisit up to 20 recent video glossaries stored locally in Chrome. • Clear locally cached analyses at any time. JargonLens supports public English YouTube videos that have existing captions. Transcript availability depends on the caption provider. JargonLens is intended only for users aged 18 or older.
