I built an AI memory engine in 10 days, then needed a project to prove it works
Parametric Memory launches a verifiable AI memory engine based on cryptographic proofs, offering persistent, tamper-evident storage with Merkle trees, Markov prediction for pre-fetching, and sub-millisecond recall. Compatible with Claude, GPT, and MCP agents, starting at $5/month.
Your AI's second brain. Ready in minutes.
Persistent, Verifiable Memory for AI
Built for developers using Claude, GPT, and any MCP-compatible agent.

Capabilities
Built on verifiable mathematics.
Not approximations or fuzzy similarity search. Every claim is provable, every number is measured in production.
Merkle Proofs
Every atom is cryptographically committed.
RFC 6962-compliant SHA-256 Merkle tree. Tamper with one atom — the root hash changes. AI clients verify integrity without trusting the server.
37% token savings vs raw proofs
Markov Prediction
Your next memory is already warm.
Variable-order Markov chain predicts which atoms you'll access next. Pre-fetches context before the query arrives. Weights decay at 0.5^(days/7) — recency matters.
64% hit rate in production
Sub-ms Recall
0.045ms p50. Not a typo.
LevelDB with JumpHash sharding across 4 independent Merkle trees. Dedicated instance means zero contention. No shared cluster, no noisy neighbours.
0.045ms p50 · 1.2ms p99
MCP-Native
25+ tools. Plug in, don't integrate.
Streamable HTTP MCP transport. Works with Claude, Cowork, and any MCP-compatible client. OAuth2 + Bearer auth. The client your AI already speaks.

Architecture
From atom to proof in four steps.
No black boxes. Every stage is deterministic, measurable, and verifiable.
01
Atom arrives
API call or MCP tool deposits a memory atom. Immediately hashed and committed to the Merkle tree.
02
JumpHash routes to shard
The atom key is deterministically routed to one of 4 LevelDB shards via JumpHash — O(1), no coordination.
03
Markov arc fires
The transition is recorded. The Markov predictor updates its weight table and schedules predictive prefetch.
04
Proof returned
On read, the atom comes with a Merkle audit path. Client verifies root hash. Tamper-evident, always.

Built on our own product
We don't just sell you a second brain. We trust it with ours.
Every billing event, health check, customer signup, and architecture decision at Parametric Memory is a Merkle-sealed atom in our own MMPM substrate. The same proofs that protect your data protect our audit trail.
If we trust it to run our company, you can trust it with your AI's memory.
