What is Sumdown
Experience YouTube summarization on autopilot.
The free tool is for one-off summaries. The full app is for people who learn from YouTube regularly and want new videos and summaries to come to them automatically.
Automatic channel tracking
Connect YouTube once and Sumdown keeps up with new videos from the channels you follow.
Your own reading queue
Save summaries in one place, come back later, and stop losing useful videos in browser tabs.
Built for long-form videos
Especially useful for interviews, lectures, podcasts, and technical explainers that are worth reading before deciding what to watch.

Frequently asked questions
How many free summaries do I get?
You get one free summary per day on this page. That makes the tool easy to try without hiding the limit or surprising you later.
What kind of summary do I get?
The summary is meant to be comprehensive and in-depth, not just a few bullet points. It is designed to help you quickly understand what the video is about before deciding whether you want to watch the full thing.
Where do I read the summary?
The email link signs you in and opens the summary inside the Sumdown app. That means the summary is saved in your account, so you can revisit it later instead of losing it in your inbox.
Do I need to connect YouTube?
No. The free summarizer works from a pasted link only. Connecting YouTube is optional and mainly useful if you want Sumdown to automatically pull videos from the channels you follow.
Why use the full app after this?
The free tool is for one video at a time. The app is for people who regularly learn from YouTube and want automatic channel tracking, a personal queue, and a growing library of summaries they can search and revisit.
How long does it take?
Most summaries are delivered in about two minutes, although longer videos can take more time depending on transcript availability and processing load.
