VERIFIABLE INFRASTRUCTURE FOR AI
Can you prove them?
EU AI Act requires tamper-evident logs. SEALISON turns every AI interaction into a cryptographically verifiable record.
HOW IT WORKS
01
Capture
Your AI generates a response to a customer.
02
Hash
SHA-256 creates a unique fingerprint of the interaction.
03
Seal
Hash is signed with Ed25519 and linked in an append-only chain.
04
Verify
Anyone can verify integrity. No server trust required.

INDUSTRIES
AI is making customer-facing decisions. Here’s where cryptographic proof matters most.
LIVE DEMO
Paste an AI interaction, generate a proof, or verify one directly.
Cryptographic proof
SHA-256 sealed in an Ed25519-signed chain.
Tamper evidence
Any change produces a completely different hash.
Independent verification
Verify in your browser. No server trust.
EU AI Act ready
Article 12 compliant tamper-evident logging.
WHEN THIS MATTERS
SEALISON is not for every AI use case. Here’s how to think about it.
▲ SEALISON WINS WHEN
You need to prove what your AI said later
You operate in regulated or high-liability environments
You cannot rely on internal logs alone
You care about integrity and external scrutiny
◌ SEALISON LOSES WHEN
You only need debugging logs
You fully trust your internal infrastructure
You optimize only for speed, not proof
You do not expect disputes, audits, or scrutiny
MARKET EDUCATION
Most teams have logs. Very few have proof.
Internal logs
Fast, cheap, useful for debugging.
Not verifiable externally
Tamper-evident logs
Append-only, audit trails.
Still requires trust in storage
Cryptographic proofs
SEALISON, Certificate Transparency, Sigstore.
Verifiable independently — no trust required
THE INSIGHT
Cryptography has existed for decades. Certificate Transparency, Sigstore, Sigsum — all used append-only signed logs long before AI.
What was missing: a way to expose it for AI outputs specifically. A browser-side verifier. A 6-month retention story. An EU AI Act-ready proof format.
That’s what SEALISON is.
PRICING
SEALISON is not a platform replacement. It is an integrity layer. Pricing should feel small relative to the risk it covers.
