Summary Box

A Chrome agent that reads your feeds and condenses them to what actually matters

Single consolidated feed

Instead of checking a dozen separate feeds, the agent brings the best items from each source into one consolidated view.

Reads beyond headlines

Summary Box opens the underlying articles, videos and threads and reads the actual content, not just the headline.

Condenses to what matters

Content is condensed down to the few things worth your time, filtered against what it has learned about your interests.

Flags new versus known

The agent tells you what is genuinely new and cuts items you have effectively already seen, so you are not reading the same story twice.

Strengths & Pros

+Consolidates many feeds into a single view instead of requiring tab-by-tab checking
+Reads full article, video and thread content rather than relying on headlines
+Flags new items and suppresses material you have already seen
+Learns your interests from normal browsing with no setup forms
