About JSR — Jargon-to-Substance Ratio
Find out how much of any text is actually saying something.
JSR reads any email, article, LinkedIn post, YouTube video, or
screenshot and tells you exactly how much is substance vs.
jargon. You get:
• A compression stat — "847 words → 94 words. 89% was noise."
• The plain English rewrite — every substantive point in
bullets
• A 0-5 JSR score — proof of how much was filler
• A jargon glossary — what buzzwords actually mean
• YouTube skip-maps — which minutes of a 45-min video are worth
watching
HOW TO USE
• Select text on any page → right-click → "Analyze with JSR"
• Click the floating JSR button on any webpage to open the side
panel
• Paste a YouTube URL to get a skip-map of the substantive
minutes
• Drop a screenshot to analyze text from images
• Keyboard shortcut: Alt+Shift+J (or MacCtrl+Shift+J on Mac)
WHAT IT'S FOR
• Emails you read twice and still don't understand
• 45-minute YouTube videos with 8 minutes of actual content
• LinkedIn posts that sound important but say nothing
• Press releases, pitch decks, earnings calls, academic papers
• Your own writing (be brave)
