Trust you can check.

Most products ask you to trust a privacy policy. MyPenny posts a public, tamper-evident record of every time your memory is unlocked — so trust isn't something we ask for. It's something you can verify.

Why each of you cares: Engineers — read the Merkle-log proofs, not the marketing. Professionals — client context encrypted, every access logged with a reason. Parents — every read of your family's data is on a record you can check. Students — real encryption, and a 30-day undo on every deletion.

Encrypted at rest, with a key unique to you

Every memory is sealed with AES-256-GCM under a 256-bit key unique to you — and the keys live in a separate, hardware-backed cloud account from the database that holds your data. A breach yields ciphertext and nothing else.

No cross-account leaks

Each record is cryptographically bound to your account and its exact location. It can't be moved into anyone else's memory — the math simply fails.

A public, tamper-evident access log

Every decryption of your memory writes a record to an append-only public log, hosted on a different cloud than your data. See every access in your dashboard, each with a reference you can verify yourself.

No private back-channel

Any non-routine access requires two founders to cryptographically sign the request and post it publicly before it can run — and a watchdog re-checks every ten minutes that the log hasn't been rewritten.

Nothing is ever silently gone

Delete a memory and it moves to a 30-day recoverable trash. No agent — even a malfunctioning one — can erase what matters before you can undo it.

Secrets never make it in

If a password, API key, or token slips into a conversation, MyPenny strips it out before anything is stored. An accidental paste never becomes a permanent memory.

No raw chat logs

Once the facts worth keeping are distilled, the raw conversation is discarded. What remains is a short, deliberate record you can read — not a transcript of everything you said.

Nothing is captured behind your back

MyPenny saves memories from the conversations and tools you've connected - never by watching your screen or recording in the background. What goes in is what you chose to connect, and every read of it is on the public log.
02 · Simple

Set it up in one conversation. Then forget it's there.

No dashboards to configure, no prompt engineering, no manual. The first time you use MyPenny, your AI offers to set it up — a handful of questions, one short snippet to paste into your AI app, done.

From then on it keeps notes for you, silently. You never say "remember this" — it captures the decisions and preferences worth keeping as you work, and recall happens on its own. Set a preference once and every connected tool inherits it.

The a-ha most people report: you tell one AI something, open a completely different one, and it already knows.

Why each of you cares: Professionals — your role and active projects captured once, carried into every session. Engineers — standards-based connect, approve once, no config files. Parents — setup is a conversation, and you decide exactly what goes in. Students — paste one snippet and never re-brief your AI again.

Up and running in four steps

1

Connect once

Authorize MyPenny in your AI tool with a single sign-in over MCP. No keys to paste, no install to babysit.
2

Just talk

Use your AI normally. Key moments become durable memories automatically — no "save this" required.
3

Recall everywhere

Open any other connected tool and it already knows you. Your memory follows you, not your model.
4

It gets sharper

A background pass consolidates what matters and refines your profile, so recall keeps improving the longer it knows you.

One memory. Every tool.
Already there when you open the next one.

Open your coding tool tomorrow morning and it already knows what you were building yesterday, or switch tools mid-project and the full context is just there. Like magic.

MyPenny doesn't live inside one chatbot. It lives at the connection layer between you and all of them — so the same memory rides along everywhere, and you stop copy-pasting context between tools for good.

Your coding subconscious. The Claude Code, Cursor and Codex plugins inject your preferences and the project's accumulated memory at the start of every session — the project recognized automatically from your repo, zero configuration. Yesterday's decisions are simply present before you type a word.

Why each of you cares: Engineers — one standard endpoint, project memory keyed off your git remote. Professionals — how you work is present in every tool without rebuilding it. Students — context built in one app follows you to the next, even when your school changes platforms. Parents — one account, any AI the family uses.

One connection, every AI

MyPenny speaks an open standard — the Model Context Protocol — so it works across Claude, ChatGPT, Perplexity, Cursor, Codex, and Claude Code, and any tool that adopts MCP next. No per-app plug-ins.

Richer while you're away

When a session ends, its secret-scrubbed transcript feeds background processing that distills what was learned into that projects living memory for next time.

Disconnect or leave when you want

Cut off any tools access from one dashboard. Your memory lives in your account, not inside your AI tools. Read, edit, delete when you want, and export is just a click away.

Import isn't a one-way-street

Plenty of products can pull your memory in (easy in but hard to get out). Yours leaves as easily as it arrives: read, edit, and delete from your dashboard, and even export. Leaving is a feature.

Memory that thinks before it answers.

An AI is only as good as what it can find. MyPenny's whole job is to surface the right thing at the right moment — even when you ask imperfectly. It searches by meaning and by exact words at once, follows a knowledge graph built from how you actually work, and consolidates everything in the background so your memory gets cleaner over time, not noisier.

The a-ha: it finds the note even though you phrased the question completely differently — and it reviewed last night's conversation while you slept, keeping only what was actually new.

Why each of you cares: Engineers — a documented, ablation-tested retrieval stack; every decision is in the source. Professionals — never re-introduce yourself to your own assistant. Parents — the essentials stay present, never buried under months of history. Students — duplicate insights merge into one clean record instead of noise.

Your AI now finds the right memory even if you phrase a question completely differently. Penny reviewed last nights conversation while you slept, keep only what was actually new.

Two Kinds of memory, just like yours

A short, always-on set of core memories rides in every conversation; everything else lives in a deep notes archive, pulled in only when relevant. the essentials make it feel like it already knows you. The archive means nothing useful is ever out of reach.

Find by meaning or exact match

Every query runs semantic and keyword search at once, then fuses the results — so you never lose a note because you phrased the question differently than you wrote it.

Consolidates while you sleep

After you work, background processing decides what's genuinely new versus already known, writes only what matters, then merges duplicates and resolves contradictions so memory stays clean.

An honest ranking, not a black box

Results are scored by a single transparent, ablation-tested formula — relevance, graph proximity, recency, and the importance you've signaled — so the right note wins even when it isn't the newest.

Memories you can measure

Structured trackers (habits, metrics, goals) and recurring rhythms (check-ins, reviews) add accountability over time — not just notes and memories. Penny can even manage your to-do list.

Honest answers

Is my memory end-to-end encrypted?
No — and we're precise about that. Your AI tools need to read your memory in plain text to use it, so end-to-end encryption isn't compatible with how a memory layer works. What we lock down instead is everything around that moment: your content is encrypted at rest with a 256-bit key unique to you, encrypted in transit, and every decryption is written to a public, tamper-evident log. We don't claim we can't read your memory; we commit that we won't — and the log means you would know if anyone ever did.
Which AI tools does it work with?
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 export or delete my data?
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.
Do you use my memory to train models?
No. Your memory exists to serve you across your own tools. The intelligence is whatever LLM you connect — MyPenny is the memory layer, not a model.
Does MyPenny store my passwords or API keys?
No. Before anything is saved, MyPenny scans for secrets — passwords, API keys, access tokens — and strips them out. If one slips into a conversation, it never becomes a memory and never shows up in search.
Do you keep my chat logs?
No. Once MyPenny has distilled the facts worth remembering, the raw text is discarded. What's kept is a short, deliberate record you can read, edit, and delete — not a transcript.
Is MyPenny open source?
No — the memory engine is proprietary. What we make verifiable instead is your access to your own data: a public, tamper-evident log of every time your memory is unlocked, plus full read, edit, and delete from your dashboard. You don't have to take our word for it.
