Hardin Memory · Hardened Memory for AI Agents

Memory Your AICan't Be TrickedInto Trusting.

Your AI's memory can be fed false information, which it then repeats as if it's true. Hardin Memory catches and throws out the fakes — and lets you prove the memory is clean. One simple API. Three lines of code.

A Notebook Liars
Can't Forge.

Normal AI memory is like a notebook anyone can scribble in — including liars. Hardin Memory is a notebook where every entry is signed and sealed, so a forged page gets spotted and torn out automatically. And you can show anyone — a customer, a regulator — that the whole notebook is genuine.

What It Does

Hardened By Design

01
🔏
Stores Sealed

Every memory is sealed with a cryptographic signature the moment it's stored, so it can't be silently changed later.

02
🛡️
Rejects Fakes

On recall, every memory is checked. Forged, poisoned, or tampered entries are thrown out automatically — your AI never sees them.

03
Proves It's Clean

One call returns a single fingerprint proving the whole memory is intact — evidence you can show your customers or auditors.

04
🔒
Stays Private

Each account has its own isolated store. Your data never mixes with anyone else's. One API call; the hardening runs underneath.

Quickstart

Two Calls To
Hardened Memory.

1 · Store a memory
curl -X POST https://memory.hardinai.co.uk/v1/memory/remember \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"text": "Customer prefers email over phone.", "kind": "fact", "source": "crm"}'
2 · Recall it (only genuine, verified memories return)
curl -X POST https://memory.hardinai.co.uk/v1/memory/recall \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"query": "how does the customer like to be contacted?", "k": 3}'
3 · Prove the whole memory is clean
curl https://memory.hardinai.co.uk/v1/memory/audit \
  -H "Authorization: Bearer YOUR_API_KEY"
# → { "verdict": "INTACT", "valid_signatures": "N/N", ... }

About

Built By Hardin AI

Hardin AI builds hardened trust infrastructure for AI. Hardin Memory is our first product: memory that can't be poisoned and can be proven clean. It's powered by our underlying TBN trust engine, which signs and governs every operation. We already run it on our own products, so it's battle-tested before it reaches you.
