AI memory that gets fact-checked before it gets trusted.
AxiomSeal runs every memory through 18 validation tests, grades it gold, silver or bronze, and seals it in a tamper-evident SHA-512 chain — so yesterday's hallucination doesn't become tomorrow's “fact”.
Every write sealed — each hash includes the one before
01 — Works with your stack
02 — Capabilities
Everything an AI needs to be trustworthy.
Bi-temporal memory
Knows when it learned a fact and when that fact was true in the world. No silent retroactive rewrites.
MCP Native
Plug-and-play with Claude Code, Cursor, Windsurf.
Swiss-hosted
St. Gallen. GDPR + Swiss DPA. Your data, your law.
Millisecond semantic search
Vector + lexical hybrid. Your AI gets context instantly.
Conflict detection
Surfaces contradictions before users see them.
EU AI Act traceability
Every memory provenanced + signed. Built for the traceability Art. 12 expects — binding for high-risk systems from 2 Dec 2027.
03 — Formal foundation
Built on mathematical axioms.
Most AI safety claims are policies. AxiomSeal's validation pipeline is grounded in formal axioms — every storage decision traces back to a rule: L→X, R→L, ¬X→¬L. Memories that violate the axioms are rejected before storage.
Formal axiom set — AxiomSeal v2
A5: L → X
Every memory entering the system must demonstrate logical alignment with the core value axis X (truth + coherence). If a candidate memory cannot be shown to be logically consistent, it is rejected at ingestion — not after deployment.
Axioms derived from Patrick Müller's Traktat X, used under license. The full mathematics remains private — by design. millerlab.io

05 — Where It Matters
Built for industries where wrong answers cost.

Compliance always depends on the overall system — AxiomSeal covers the memory layer (tamper-evident records, provenance, signed exports). No legal advice.
06 — Before / After
Same AI. Different outcome.
Without AxiomSeal
- Hallucinated facts get stored
- Contradictions surface in front of users
- No audit trail when the model drifts
- Compliance teams ask: prove it
With AxiomSeal
- Memories pass 18 tests before storage
- Contradictions caught and flagged at write-time
- Every memory is signed (Sigma hash) + timestamped
- Export-ready provenance for EU AI Act traceability

07 — Architecture
Sits beside your stack. Not on top of it.
Memory flows in both directions. AxiomSeal validates everything before it returns to your LLM and before it is stored.
08 — Connect

“I built AxiomSeal because I needed an AI assistant that wouldn't quietly drift. The world is choosing AI for decisions that hurt when AI is wrong. I refuse to ship one more system that cannot prove its own coherence.”
— Martin, founder. St. Gallen, Switzerland.
10 — Why this exists
Built by an operator, not a research lab.
AxiomSeal grew out of 9 months of running a persistent AI system in production. Every contradiction the system tried to commit became a test case. Every hallucination became a validation rule.
The result is not theoretical. It is a working coherence layer with 4,500+ validated memories in production. Every memory carries a SHA-512 seal — silent edits break the chain and get caught.
Every memory gets tested before it gets trusted. What fails validation is flagged or quarantined — not silently stored. That is the whole product.
11 — Questions
Questions you probably have.
No. It is a coherence layer that sits beside your AI assistant. It connects over the Model Context Protocol (MCP) — today via Claude Code, Cursor and Windsurf. GPT, Gemini and local-model setup guides are on the roadmap. AxiomSeal validates what goes in and what comes back.
