Marrow

A crawler for AI agents. It crawls, watches, and keeps your data fresh — so your agent doesn't have to.

The layer beneath your agent

Section titled “The layer beneath your agent”

Claude, Codex and Gemini can already search. Marrow is the layer underneath — it gets the data, watches it, and keeps it fresh. The AI stays with your agent; Marrow stays a crawler.

scout → read

Scout a page’s links and structure cheaply, then deep-read only what matters — fewer tokens burned.

Change tracking

Re-read a URL and get a section-level diff — added / modified / moved / removed, with stable ids. The diff rides free.

Flat-rate monitoring

Watch pages on a schedule. Frequency is free — no per-check charge.

Cache as standard

Re-reads are near-free. The second fetch of any URL is fast and cheap.

Section titled “Why not just my agent’s search?”

Search answers questions. Marrow keeps knowledge current. Your agent does the thinking; Marrow feeds it clean, fresh data — and tells it exactly what changed. The AI lives in your agent, not in the crawler.
