Read less, know more. An agent that reads the web for you and condenses it to what matters. Read less. Know more.
More is published every day than anyone could ever read. Summary Box is a compression layer for the web: an agent that does the reading for you, condenses it to what actually matters, and gives you the signal without the scroll.
Here is how it works. Summary Box runs on the feeds, sites, and pages you already visit, like YouTube, X, Reddit, and the news you read. It learns what you care about right away, with no forms or setup. Then the agent goes through those feeds for you: it opens the articles, videos, and threads, reads the actual content, weighs it against what you already know, and pulls out the handful of things worth your time.
Everything it finds lands in one place. Instead of checking a dozen feeds, you get a single view with only the best of each, condensed to the point. It even tells you what is genuinely new, so you are never reading the same story twice.
The more it reads for you, the less you have to read yourself. That is the whole idea: read less, know more.
