Summary Box
Summary Box is a Chrome extension that reads your logged-in feeds across YouTube, Reddit, X, LinkedIn, Hacker News, and Substack, then returns a digest of what is actually worth your time.
Instead of skimming every platform separately, an agent browses in a visible window on your machine using your existing sessions. Each card in the digest includes a one-line reason, and you can skip, save, or research anything with receipts tied back to the source.
It targets people whose feeds outgrew manual reading: newsletter writers, researchers, and heavy social media users who want compressed understanding without giving up logged-in sources cloud tools cannot reach.

How is Summary Box different from browser-built AI?
Summary Box reads your actual logged-in feeds in a browser window on your machine, including sources behind login walls that cloud AIs cannot access. It returns a ranked digest with reasons rather than a generic page summary.
Does Summary Box access my bank or brokerage accounts?
No. Summary Box permanently blocks financial sites such as banks and brokerages. The agent only reads the content feeds and platforms you configure.
How much does Summary Box cost?
Summary Box offers one paid plan at $9 per month when billed annually ($108 per year), or monthly billing at a higher rate. A 5-day free trial includes the full product with a card on file but $0 charged today.
Do I need an account to try Summary Box?
You can add the Chrome extension and build your first feed free without an account. The paid trial requires signing up through the website.
Which platforms does Summary Box support?
Summary Box works on YouTube, X, Reddit, LinkedIn, Hacker News, Substack, ChatGPT, and Claude, plus general page and PDF summarization from the extension.
