Penny coin

Penny for your thoughts.

Your AI memory, secured in a vault, crazy smart, and simple to use seamlessly with all your tools.

You're a stranger to every new AI. Never to me.

I'm Penny. I carry your memory across every AI you use - ChatGPT, Claude, Perplexity, Cursor, Codex, whatever comes next. They learn you, then keep it to themselves. I'm where it lives instead. Tools come and go. I stay.

Walk out anytime.
No permission needed.

One command, and every note, every preference, every project comes with you. Portability isn't a favor here. It's the point.

Yours - and sealed.

Your memory, notes and other data are encrypted, and every time it's unlocked, that goes on a public record you can check.

You're the customer,
not the product.

You pay for me, so I answer to you. Your data is yours to keep and it's only used when you give permission.

Private, portable, and protected.

For most AI, import is a one-way street. Easy in, no way out. Your memory should leave as easily as it arrives - one command, everything, yours.

Works with every AI tool.
Even the ones not invented yet

MyPenny speaks the Model Context Protocol - the open standard used by Claude, ChatGPT, Perplexity, Cursor, and Codex today. One connection, no per-app integration, no lock-in. Stop using one AI and start using another with no gaps.

Encrypted & Private
With receipts to prove it

Every memory is sealed with AES-256-GCM under a 256-bit key unique to you, stored apart from your data — so a leaked database is unreadable. We publish a public, tamper-evident log so you'll know if anyone ever accessed your notes and information without your permission.

We built Penny for ourselves, and security and privacy matter to us.

Better than human memory

Every search runs by meaning and by exact words at once, then fuses the results — so the note surfaces even when you ask the question differently than you wrote it.

Leaving is a feature.

Read, edit, and delete your memories and notes anytime. Export on request today; one-click export on the way. Your memory belongs to you - leaving proves it.

Memory that improves over time

Just like human sleep, background consolidation weighs recency and importance, keeps what's durable, and lets the rest fade — the way memory is supposed to work. And it all happens safely and securely.

Skills that work everywhere

Tired of trying to copy skills between AIs? Not only can Penny make skills universal, but can also have timing instructions that can run on a schedule.

Skills that work everywhere

Penny makes your AI tools work like they are supposed to.

I almost forget that I'm using Penny until Claude reminded me of something I had done weeks ago that was already complete. I had forgotten!

Francisco

I work in several different coding tools, and the cool thing is that I can jump between them and not skip a beat because Penny remembers everything.

Matt

Seriously, I almost can't believe how little I have to remind GPT of something. It used to happen multiple times a day, now it just knows me.

Carly

This is the best AI memory system I've ever used. It's so incredibly easy to get started and it has way more powerful memory and note capture than anything I've tried.

PROOF

Don't take our word for it,
read the nerdy details for yourself.

The log is public

Every time your memory is decrypted, a record is written to an append-only, tamper-evident log - on a different cloud than your data. You can see every access in your dashboard.

  • • A public tamper-evident log shows access
  • • You have your own private key, stored in a separate vault

Encrypted at rest and in-transit

AES-256-GCM, a 256-bit key unique to you, keys stored in a separate hardware-backed account from your data. A leaked database is unreadable.

  • • Only decrypted when you need it
  • • Memory encoding and indexing never leave our servers.

Your memory belongs to you. Not to an AI company.

Questions.

Where is my memory stored?
On infrastructure we run for you, encrypted at rest with a 256-bit key unique to you — so a leaked database is unreadable. We don't claim we can't read your memory; we commit that we won't, and every decryption is written to a public, tamper-evident log you can audit. The AI tools you connect see only what they ask for, when you ask.
Which AI tools work with MyPenny?
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 everything?
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.
Can I delete a memory?
Yes — one memory, a tag, or all of it. Deleted memories sit in a 30-day recoverable trash, then they're gone for real. Deletion is deletion, not a soft flag.
Do you train on my data?
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.
What if I stop paying?
You get an export window. After that we delete what we hold, because it's yours.

Ready when you are.
