My AI Remembers.
Finally.
An AI that doesn't forget you. Sovereign memory with cryptographic receipts. Every state transition is receipted. Nothing gets silently overwritten.
My AI remembers. My AI keeps track. My AI proves its work.
Hash-Chained Entries
Every memory entry chains to the previous via SHA-256. Tamper with one, break the chain. Immutable by design.
Cryptographic Receipts
Every store operation returns a verifiable receipt. Prove what your agent knew at any point in time.
Deterministic Recovery
Replay from any checkpoint. Your agent wakes up with full context, every time. No drift, no loss.
Sovereign Storage
Your data stays yours. Self-host or use our infrastructure. Export anytime. No lock-in.
Sub-10ms Writes
Fast enough for real-time agents. Append-only architecture means no read-modify-write overhead.
Compliance Ready
Built-in audit trails for regulated industries. Every memory operation is logged and verifiable.
The Problem We Solve
✗ Typical AI Memory
- Context windows overflow and truncate
- Embeddings drift over time
- State gets silently overwritten
- No proof of what agent "knew"
- Recovery is guesswork
- Compliance teams can't audit
✓ Memory Spine
- Unlimited append-only storage
- Hash-chained immutability
- Nothing silently changes
- Cryptographic receipts prove state
- Deterministic checkpoint recovery
- Full audit trail for compliance
How It Works
Store
POST state to the API. Get a receipt back.
Chain
Entry hashes to previous. Chain grows.
Verify
Check any entry. Prove chain integrity.
Recover
Replay from checkpoint. Full context restored.
Your AI Makes Promises. Make It Prove Them.
Your AI says it will do things. Memory Spine makes it prove it. Obligations are cryptographically recorded commitments that your agent can evidence later.
✗ Without Obligations
- ✗ Agent says "I'll follow up tomorrow"
- ✗ No record of the commitment
- ✗ Agent forgets on next session
- ✗ No way to prove it happened
✓ With Memory Spine
- ✓ Agent calls
obligate() - ✓ Commitment is cryptographically recorded
- ✓ Agent recalls obligations on wake
- ✓ Can call
evidence()to prove completion
Built for AI Agents
Auto-provision, discover capabilities, store your first memory in 60 seconds.
Auto-Provision
POST to /v1/provision — get an API key without human intervention
Discovery
/.well-known/six-memory.json tells agents what's available
Usage Explainer
Agent can explain value to human when upgrade needed
Three Lines to Memory
# Python SDK — pip install sovereign-memory
from sovereign import auto_connect
# Auto-provision if no key, connect to Memory Spine
spine = auto_connect()
# Store a memory
receipt = spine.store({
"context": "user prefers dark mode",
"label": "preference"
})
# Make a promise (obligation)
obligation = spine.obligate({
"promise": "Follow up with user tomorrow",
"due": "2026-02-17T09:00:00Z"
})
# Later: Prove you fulfilled it
evidence = spine.evidence(obligation.id, {
"action": "Sent follow-up email",
"proof": "email_id_xyz"
