See how AI thinks.
Compare. Decide. Trust.
NotaryOS is an AI Decision Plane. Run your question through multiple AI models in parallel, visualize their reasoning trees, see where they agree and diverge—and seal every decision with cryptographic proof.
PROMPT
“Should we acquire CompanyX at $2.1B?”
Acquire
Cautious
Acquire
Risk Flag
3/4 models favor acquisition. KIMI flags regulatory risk in EU markets. Consensus: 72% — Acquire with regulatory due diligence.
One prompt. Four AIs. One decision.
The Reasoning Forge runs DeepSeek, Gemini, Sonnet, and Kimi in parallel on your prompt, then synthesizes their reasoning into a weighted decision—with full provenance.
Proof of what your AI chose not to do
Two live-signed receipts. One action taken, one deliberately declined. Linked by a tamper-evident hash chain and independently verifiable.
The AI Decision Plane
Multi-model reasoning. Decision tree visualization. Cryptographic trust. All in one platform.
Multi-Model Reasoning
Run your prompt through DeepSeek, Gemini, Sonnet, and Kimi in parallel. See how each AI reasons — not just what it concludes.
Decision Tree Visualization
Every reasoning step extracted and visualized as an interactive tree. Expand branches, explore logic paths, compare depth.
Counterfactual Analysis
Cryptographic proof of what AI considered but chose not to do. Explore the roads not taken in every decision.
Cryptographic Trust Layer
Every reasoning node, every synthesis step, every decision sealed with Ed25519 signatures. Tamper-proof by default.
Not another chatbot.
NotaryOS doesn't give you one AI's opinion. It shows you how multiple AIs reason—and proves it.

How the Decision Plane works
From prompt to provenance-sealed decision in seconds.
You ask a question
Enter any prompt — investment analysis, architecture decision, legal review, strategic planning.
Models reason in parallel
DeepSeek, Gemini, Sonnet, and Kimi analyze your prompt simultaneously with full reasoning chains.
Synthesis reveals consensus
The Master Synthesizer weighs each model's analysis, identifies agreement, divergence, and blind spots.
Decision sealed with proof
Every reasoning node and the final synthesis sealed with Ed25519 signatures. Verifiable, tamper-proof.
Decisions that matter deserve more than one opinion.
Investment analysis
Should you buy, hold, or sell? See consensus across 4 models with confidence scores and risk flags.
Legal & compliance review
Get multi-perspective analysis on contracts, regulations, and risk — with cryptographic proof of the reasoning.
Architecture decisions
Monolith vs microservices? Which database? Let 4 AI models debate the trade-offs before you commit.
Strategic planning
Market entry, pricing strategy, competitive positioning — synthesized intelligence from multiple reasoning engines.
The only decision engine with cryptographic provenance.
Every reasoning step, every model weight, every synthesis node sealed with Ed25519 signatures and chained into a verifiable provenance DAG. Not just transparency—mathematical proof.
