Send articles and PDFs to your Kindle to read later

Quick answer

Long articles are easier on an e-ink screen than a laptop full of tabs. Amazon has several ways to get them there.

What 125x is: 125x is a web app at 125x.app. You connect your YouTube subscriptions, and it gives you a feed of the latest videos from the channels you follow, each with a summary: a verdict, the 5 key takeaways, and the spoiler, plus Actionable and Lessons tabs with more tips. You read that and decide what's actually worth opening.
