The Deterministic Knowledge Engine
Memory your LLM can prove.
DKE is the deterministic engine your assistant connects to for memory and reasoning it can trace. Your LLM writes DKE Python; DKE runs it and hands back answers grounded in the facts they rest on — not guesses. Three ways in: attach it over MCP, try it free in DKE Studio, or read the published docs.
What we ship
One engine, three ways in.
DKE is the engine LangSyn sells: deterministic memory and reasoning your LLM can prove. You reach it three ways — connect an agent over MCP, try it live in DKE Studio, or read the language it speaks.
DKE MCP — attach the engine to your LLM
Engine live · opening for NorwayDKE runs as a service your assistant connects to over MCP. Hand it your access key and it can store what it learns, recall it later, and answer from it — every result grounded in the facts it rested on, traceable, and the same every time you ask.
Live at dke.langsyn.net. DKE access is opening for Norway, verified with BankID; key issuance is paused until the gate is live.
DKE Studio — try it in your browser
The fastest way to see DKE work. Open DKE Studio, run a real DKE Python program, and watch the answer come back grounded — free, no signup, nothing stored. Each run gets a fresh, disposable workspace.
DKE docs — the published language
Your LLM programs DKE in DKE Python, an open, published language. The specification is MIT: read it, build your own tooling against it, and know exactly what the engine will and won't do before you attach it.
Why it matters
Why memory and reasoning, not more LLM.
LLMs are powerful and forgetful. Every session forgets, every answer drifts, every claim is unauditable. The cloud-RAG fix puts your data in someone else's vector store and bills per token. Traceability has been traded for convenience.
DKE takes the memory and reasoning out of the LLM and into a deterministic engine your LLM holds a key to. Your LLM writes DKE Python; DKE runs it and returns grounded answers you can trace back to what you taught it. Same conversation, same answer, every time.
DKE Studio is the on-ramp: open it, run a DKE Python program, watch an answer come back grounded — no signup, nothing stored. If it changes how your work flows, create an account and keep the engine attached with your own key.
