Ejentum

Inject engineered cognitive abilities into AI agents at inference time to prevent reasoning decay.
Visit

Ejentum is a reasoning harness for agentic AI that injects structured cognitive abilities into LLM agents at inference time. With 679 abilities across four harnesses—Reasoning, Code, Anti-Deception, and Memory—it prevents reasoning decay in multi-step chains. Agents call Ejentum as a tool mid-task and receive a cognitive operation matched to their problem, improving reliability, auditability, and cost-efficiency. Compatible with any LLM and major frameworks like LangChain, CrewAI, and n8n via API or MCP.

How to use Ejentum?

Integrate Ejentum as a tool in your AI agent's loop. Sign up for a free API key, then call the Ejentum API from your agent's code using the provided endpoint. The API returns a cognitive operation (JSON) containing a failure guard, step-by-step approach, reasoning structure, target pattern, shortcuts to suppress, and falsification check. Inject this into your agent's context before task execution. For no-code setups, wire Ejentum as a tool node in n8n or Make.com. For MCP clients, connect to api.ejentum.com/mcp. Use the dynamic mode for speed or adaptive mode for tailored reasoning.
