Parametric Memory — Persistent, Verifiable Memory for AI
Parametric Memory · 2026-06-23 · via Hacker News - Newest: "AI"

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.

25 MCP tools · Streamable HTTP

Architecture

From atom to proof in four steps.

No black boxes. Every stage is deterministic, measurable, and verifiable.

  1. 01

    Atom arrives

    API call or MCP tool deposits a memory atom. Immediately hashed and committed to the Merkle tree.

  2. 02

    JumpHash routes to shard

    The atom key is deterministically routed to one of 4 LevelDB shards via JumpHash — O(1), no coordination.

  3. 03

    Markov arc fires

    The transition is recorded. The Markov predictor updates its weight table and schedules predictive prefetch.

  4. 04

    Proof returned

    On read, the atom comes with a Merkle audit path. Client verifies root hash. Tamper-evident, always.
