Sign every diff your AI writes.

Get a public verify URL. Audit-grade provenance for the AI era.

The Problem

Context Loss

AIs forget between sessions, tools, and teams. Every new conversation starts from zero.

No Provenance

AI artifacts have no verifiable origin. Who wrote what, when, and under which constraints?

Regulatory Pressure

EU AI Act deadline Dec 2027. Organizations need audit trails for AI-generated content now.

Three Pillars

Persistent Memory

Context that travels across sessions, models, and machines. Never explain your project twice.

Cryptographic Provenance

Ed25519-signed artifacts with public Evidence URLs. Every diff has a verifiable author and timestamp.

Auditable Governance

CT-compatible transparency log. Compliance-ready for EU AI Act, SOC 2, and enterprise audit requirements.

How It Works

Sign
Classify
Stamp
Log
Verify

Every artifact gets an Ed25519 signature, SHA-256 hash, OpenTimestamps anchor, and a public Evidence URL.

Simple pricing

Free to self-host forever. Pro from $29/mo when you want managed engine, log retention, and seats — early access $9/mo locked for life.

SEIF is to AI-coding state what Git + GitHub is to source code

An open protocol you run locally, plus optional managed infrastructure at seifprotocol.com — same CT-verifiable evidence URL either way. Self-host forever free; managed SaaS when you need zero ops.
