Memory layer for Claude Code, Cursor & any MCP client

AI memory that gets fact-checked before it gets trusted.

AxiomSeal runs every memory through 15 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”.

Built on formal axioms

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 the EU AI Act expects (Art. 12, from Aug 2026).

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.

04 — Validation

15 tests. Before storage. Every time.

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 15 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.

“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.

09 — 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 3,000+ 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.

10 — Questions

Questions you probably have.

No. It is a coherence layer that sits beside your existing LLM. You keep Claude, GPT, Gemini, or a local model. AxiomSeal validates what goes in and what comes back.
