Claude is known for its accuracy, nuance, and ability to understand complex technical material. Unlike basic summarizers that just pull random sentences, Claude actually understands the content and structures it into a format optimized for studying: definitions first, then formulas, then application, then examples. It's the difference between a highlight reel and a real study guide. --- 🔒 PRIVACY & SECURITY Your data is yours. Always. - Video transcripts are sent directly to Anthropic's API - we never see or store them - Your cheatsheets are saved locally in your browser — never uploaded anywhere - We do not track your browsing history - We do not sell your data to advertisers or data brokers - Payments are handled entirely by Stripe — we never see your card details Full privacy policy available in the extension's Settings page. --- ⚡ FREE VS PRO Free (no account needed): - 3 cheatsheets to try the extension - Full feature access - All export and sharing options Pro ($10/month): - Unlimited cheatsheets - Full history access - All features included - Cancel anytime --- 🛠️ SETUP IN 2 MINUTES 1.

Just install, and go. --- ❓ FREQUENTLY ASKED QUESTIONS Does it work on all YouTube videos? It works on any YouTube video that has transcripts, captions, or auto-generated subtitles. Most educational videos have these. If a video has no captions at all, the extension won't be able to generate a cheatsheet. How much does it cost to use? The extension itself is free for 3 cheatsheets, then $10/month for unlimited. Does it work with non-English videos? The extension works best with English-language videos. It may work with other languages depending on caption availability, but results will vary. Can I edit my cheatsheet after it's generated? Yes — click the Edit button in the action bar to edit your cheatsheet directly. Your edits are saved automatically. What if I don't like the cheatsheet? You can regenerate it by clicking the button again, or edit it manually to add or remove content. --- No more pausing videos or scrubbing through lengthy lectures to capture important details. Save it. Study it. Share it. Get started today and make studying easier with YouTube Summarizer!
