Summary Box

What is Summary Box?

Summary Box is an AI feed reader and research assistant delivered through a Chrome browser extension. Summary Box reads content from existing logged-in feeds and condenses posts, videos, threads, and comments into a personalized digest. The service is aimed at readers who want to follow their interests and subscriptions without reviewing every item individually.

Summary Box combines feed selection with research assistance rather than providing summaries alone. Digest cards include reasons for their selection, while roundups connect information across sources. A concierge panel also offers research errands drawn from the reader’s profile and feeds, with source references attached to answers.

What Summary Box can do

Summary Box organizes reading around personalized feeds, source-backed answers, and compressed explanations. Supported feed sources include YouTube, Reddit, X, LinkedIn, Hacker News, and Substack. Summary Box also summarizes individual pages and documents, allowing readers to move between a broad digest and a focused question about selected material.

How Summary Box works

Summary Box uses a ghost browser window on the user’s own machine to access feeds through existing sessions. Summary Box can therefore read subscriptions and logged-in threads without requiring accounts to be reconnected. Clicking the extension icon opens a panel containing the digest, cross-source roundups, and concierge research options.

Summary Box personalizes results using what the reader reads, skips, saves, asks, and revisits. Each inferred preference has a supporting source, and the reader can correct profile facts. Those corrections inform the digest, suggested research errands, and chat. Citation highlighting connects an answer back to its source material.

Who Summary Box is for

Summary Box is for Chrome users who follow multiple feeds, investigate topics, or compare information spread across posts and discussions. The website illustrates research into home-office purchases and developments in AI agents. Summary Box supports these tasks by bringing together reviews, comments, and source references rather than presenting isolated summaries.
