Inside the product
What you can actually do with it.
The core product capabilities, grouped around the work they enable.
Evidence-ranked digest
Reads selected logged-in feeds and returns cards with a one-line reason to open, skip, or recognize already-read items.
Ghost Browser
Uses a visible browser window on the user's machine to read feeds and threads with the user's existing sessions.
Research concierge
Lets users research highlighted content or ask questions, returning compressed answers with clickable receipts.
Typical workflow
Add the Chrome extension and use the feeds you already browse. Summary Box's local Ghost Browser reads those sources while logged in as you, then builds a ranked digest and cross-source roundups. Open a card or use the panel to research a selection and follow each result back to its receipts.
