Comparison

How mantle compares.

Memory layers remember conversations. Search tools retrieve documents. Mantle builds a typed, permissioned graph of your business, the kind of ontology you'd get from a Palantir engagement, self-serve, in minutes, readable by any agent over MCP.

Comparison reflects publicly documented features as of 2026. “Partial” denotes in-progress or limited availability. Glean is built for people searching; Mantle is built for agents reasoning. Memory layers are per-agent; Mantle is the shared graph every agent reads. Get in touch if anything is out of date.

The shortest version: agent memory remembers what your agent saw. Mantle knows what your organization knows.
