Memory that holds. Limits that hold.

HyperMind remembers useful context across conversations—and you can read, edit, or remove any detail. Consequential actions pause at an approval gate until you decide.

HyperMind & CortexContinuous Temporal Memory

Sensitive writes, outbound messages, and spending actions pause with their plan and reasoning in view. Capability never grants itself permission.

Every completed run produces a signed, replayable receipt: inputs, outputs, tool activity, and provenance attached to the finished artifact.

Archive: Centra's July 2026 operator preview.

A dated account of the early operator preview, kept as originally published. Neo has since been retired and replaced by Gideon; current availability lives on the pricing page.

Receipts, not screenshots.

The difference between an agent telling you what it did and proving it. Anatomy of a Centra receipt, and why replayability is the property everything else stands on.

Archive: the silent voice inside early Neo supervision.

A historical design note about in-loop supervision. The separate verifier described here is no longer a public agent or a terminal completion gate.
