Summary Box

Summary Box reads your feeds in your browser, logged in as you, and ships back a digest of what’s worth your time, with receipts that explain each pick. It operates across YouTube, Reddit, X, LinkedIn, Hacker News, Substack, and more, aggregating what matters from your real feeds and presenting it in a compact form.

The agent runs in a window on the user’s machine, in their browser, reading the feeds and threads as they exist and providing a digest of the few items that are most relevant. It keeps logins, subscriptions, and context in the foreground, with the work shown rather than hidden. It is a concierge-like assistant that can be prompted to investigate topics and return receipts for claimed conclusions.

Core capabilities include reading feeds, generating digests with one-line reasons, providing compressions of long content, and offering receipts linked to sources. It supports article and PDF Summaries, YouTube breakdowns with timestamps, and right-click research that returns results with receipts. It also includes a digest that consolidates across multiple sources to highlight the most useful items.

It implies availability in a browser-based environment with ongoing updates and support.

Use cases
