Nothing worth keeping gets forgotten.

Tell it once. Cyphra keeps it — not as a transcript to replay, but as structured memory it can reason over. This is the mechanism underneath the promise.

The mechanics

Retain

OP · 01

Everything you tell Cyphra is stored as structured memory — facts, preferences, decisions — not a transcript to replay.

Recall

OP · 02

Relevant memory is surfaced automatically before each response, ranked by meaning rather than keywords.

Reflect

OP · 03

Cyphra can reason across everything it has stored — synthesizing an answer from your whole history, not just the nearest chunks.

Isolated banks

OP · 04

Memory is organized into banks with per-bank access control. Your bank is yours — isolated, exportable, and deletable.

Underneath

Hindsight

Cyphra's memory runs on Hindsight, an open-source agent memory system that ranked state-of-the-art on the LongMemEval benchmark. It is integrated through Hindsight's official Hermes integration — the same memory engine, hosted and managed for your instance.

Your bank is yours

Memory is structured — facts, preferences, and decisions, not raw transcripts. Each client's memory lives in an isolated bank, and it is exportable and deletable on request. Retaining context for you is not the same as owning it.
