One memory across every tool. Readable, auditable, exportable.

MyPenny is a memory layer exposed over MCP: one endpoint, any MCP-capable client, no per-app glue. You can read the audit trail instead of the marketing.

What we won't tell you

It is not end-to-end encrypted. AI tools need plaintext to use memory, so E2EE isn't compatible with a memory layer that works. We lock down storage and transport instead, hold the keys, and say so. We don't claim we can't read your memory; we commit that we won't - and the public log means you'd know if anyone ever did.

It is not open source. The engine is proprietary. What's verifiable instead is every access to your own data, plus full read, edit, delete - and export on request today, one-click export on the way.

Embeddings are a disclosed limitation. Vectors are stored readable because search requires it, and published research shows embeddings can be partially inverted. We disclose it rather than imply otherwise. Full privacy and security detail.

The system, plainly

Transport

Standard MCP. OAuth authorization-code flow with PKCE; tokens scoped per account; revoke any client from the dashboard, effective immediately.

Storage

AES-256-GCM per record under a per-user key, envelope-wrapped by keys in a separate AWS KMS account from the database. A leaked database is ciphertext.

Access accountability

Every decryption writes to an append-only, tamper-evident log on a different cloud than the data. Non-routine admin access requires two founders' cryptographic signatures, posted publicly before it runs.

Retrieval

Hybrid semantic + lexical search fused per query, a typed memory graph over your tags and note links, and a transparent scoring formula: relevance, graph proximity, recency, signaled importance.

Hygiene

Secrets are stripped before storage. Raw transcripts are discarded after distillation. Deletion is real, with a 30-day trash.

Coding subconscious

The Claude Code plugin injects your preferences and the current project's accumulated memory at session start. Cursor and Codex plugins are available today.

Questions engineers ask

Why not build it yourself?
You could. Most of us have, at least twice. The product parts are the consolidation pipeline, tamper-evident logging, per-user key isolation, and maintained plugins across clients. $99/year; first 250 accounts are $49/year, locked for life.
Which clients work today?
Any tool that speaks the Model Context Protocol. Today that includes Claude on desktop and web, ChatGPT, Perplexity, Cursor, and Codex - with more arriving as MCP adoption grows.
Can I leave?
You can read, edit, and delete your memories and notes from your dashboard today, and request a full export anytime - we fulfill export requests on request. One-click export in a portable format is on the way. Your memory is yours; we just hold it.
Pricing
