Cognitive memory
for AI agents.

A persistent-memory substrate that lets your coding assistant, support bot, or research agent remember context and recall what matters — across sessions, workspaces, and restarts.

$ pip install cogitent
$ cogitent-mcp serve --transport stdio
# your agent now has long-term memory.

LLMs are powerful but amnesiac. Their context window forgets everything the moment a session ends. Cogitent is the missing substrate: episodic storage, salience-weighted recall, and consolidation cycles inspired by how cognition actually works. It works across MCP-compatible AI hosts and major providers, so your agent keeps its memory whichever model you run.

What's in the box

Persistent recall

Episodes survive across sessions, workspaces, and host restarts. Cache-hit recalls return in <1 ms; semantic recalls in <50 ms p50. Retrieval quality measures 65.0 % LongMemEval-S, fully local (retrieval-quality measurement).

Salience-weighted

Five-axis salience (importance, urgency, novelty, confidence, affect) ranks what surfaces. Background sleep cycles consolidate, decay, and settle revisions — a unique cognition architecture among surveyed memory platforms. Predictive recall was measured against a pre-registered bar and did not clear it; see the roadmap.

Open core, EU-built

AGPL-3.0-or-later Community Edition — free and self-hostable forever. Memory is stored and processed locally; recalled context is shared only with the AI host you choose. French-hosted federated learning is on the roadmap. Plus for AI-intensive individuals & small teams, Pro for enterprises; full self-host always supported.

Governed memory

A memory is evidence by default — it only becomes something your agent treats as an instruction after an explicit human confirmation. Per-memory use-class, sensitivity, and sharing rules are enforced by a single fail-closed gate on every read. The gate ships off by default with a shadow mode, so you can measure its blast radius before it ever denies anything. Sensitivity & retention enforcement is a Pro feature.

Editions

CE is the individual layer, free forever. Organisations buy governance and accountability — never access to their own memory.
