Jachin is a Christian AI ecosystem driven by the COOS-Symbolic engine. The engine formalizes the Christian worldview into a reasoning-capable ontology, and every product below runs on it. The result: verifiable reasoning, traceable conclusions, zero hallucination.
Two products are already running on the engine — open them right now.
The Gospel of Mark in Traditional and Simplified Chinese, English, and Indonesian — side-by-side versions, notes and highlights, and a reading agent that answers from the text itself.
A daily feed for the believing household, with a built-in agent that understands natural language — and keeps every structured action behind a confirmation gate.
Curriculum and school administration for Christian schools, co-built with the AI-native school Hora. Rolling out scene by scene.
Our first commercial product: a shared symbolic protocol between AI agents for A2A commerce. Buyer and seller agents negotiate through a formal constraint layer — every inference verified, every decision auditable, every proof chain complete.
One buyer agent simultaneously negotiates with multiple suppliers. Each session is semantically isolated but formally consistent through the shared protocol.
From inventory trigger to supplier selection to payment execution — the complete decision chain is recorded as a verifiable proof. Why this supplier? There's a logical answer.
Jachin's product evolves in two phases. Phase 1 deploys human-written symbolic rules as formal constraints — deterministic, auditable, ready today. Phase 2 introduces the full ontological layer, where AI no longer needs hand-written rules — it emerges its own reasoning from world structure.
Explicit inference rules, type-checked semantic alignment, state machine negotiation tracking, complete proof chain output. The transitional stage: humans write the rules, machines follow with full verification.
Formal substance-accident distinction, causal reasoning via four causes, cross-domain functor mapping. The endgame: AI reasons from world structure, rules are emergent — not preset.
Every output has a traceable proof chain. Not "probably right" — provably right. Each step follows declared logical rules.
The protocol layer type-checks every claim against the shared ontology. Agents cannot hallucinate terms, prices, or conditions.
Category theory functor mapping preserves logical structure across domains. One reasoning framework for education, commerce, and operations.
As the ontological layer matures, AI derives its own reasoning from world structure — not pattern matching, not hand-written rules.
Formal distinction between substances, properties, events, and relations. The AI understands that different things exist in fundamentally different ways.
When data is insufficient, the system refuses rather than guesses. It tells you what it doesn't know and why.
Socratic reasoning engine that teaches students how to think. Not answers — the logic behind answers.
Theological inquiry engine that reasons through Scripture. Multiple interpretive paths, each logically traced.
A2A procurement through the protocol layer. Buyer agent negotiates with multiple suppliers — every decision auditable.
