Why use this key points extractor
Ranked, not random
The most important takeaway comes first. You read the list top down and stop when you've got the gist.
A real TL;DR
Short bullets, not prose. Use it when you want the point fast, without reading a summary.
Checklist mode
Tick each point once you can explain it in your own words. The list tracks what you've got and what's left.
Listen, copy, or export
Hear the points read aloud, copy one or all, or download them as Markdown, text, or CSV.
Who it's for
Students
Get the main ideas of a lecture or reading before class, so you follow it instead of scrambling to keep up.
Researchers
Pull the takeaways from a talk or paper to decide fast whether it's relevant to your work.
Content creators
Turn a long source into a punchy bullet list you can build a script or post around.
Questions
What's the difference from a summary?
Key points are a short bullet list of the most important takeaways, ranked. A summary reads more like sectioned prose. Use whichever fits.
Can I use it on a YouTube video?
Yes, if the video has captions. Paste the link and get the takeaways without watching the whole thing.
Is it free?
Yes, no account needed. Sign up free to save your notes and build a full study kit.
