THE INSULATED MEMORY LAYER FOR ANY AI
Your AI remembers you — with receipts.
Every memory is a fact with its source attached. Nothing an AI remembers about you goes live until you approve it. Forgetting takes a reason.

SEEN IN THE WILD
This is what remembering looks like
“Since you land at 14:05 on Friday, you’ll probably first get there on Monday.”
A real traveler asked their Claude for the restaurants saved near the Lisbon hotel. Myeline served four approved facts (one coffee, three dinners, with addresses, hours, and walk times) and Claude did the travel math: the weekday-only café is a Monday thing. No re-explaining, no copy-pasting, no guessing.
The math, both sides measured
Building this memory the first time (the searches, maps, and saves) cost ~17,500 tokens of content by Claude’s own in-conversation accounting, plus the hidden tax of re-reading the whole context every step (~600k input tokens processed).
The recall, served by Myeline into a brand-new conversation: 1,433 tokens, measured, off the same ledger that counts the live numbers above. About 12× less content, and the re-read tax never happened.
Real conversation from a real phone (cropped for size). Every place above was a fact with its source, approved by a human before any AI could see it. The first-build figures are the AI’s own itemization; the recall figure is the engine’s ledger row.
WHAT IT IS
One memory for every AI you use
Myeline is a memory layer for AI assistants. It plugs into Claude, ChatGPT, and any client that speaks the Model Context Protocol (MCP), and keeps what your AI learns about you as single facts, each with its source attached. Ask a question later and the answer cites where it came from; if nothing you approved matches, Myeline says so instead of guessing.
The name is from myelin, the sheath that insulates nerve fibers so signals travel fast and arrive intact. Myeline does that for memory: it sits between your AI and what it remembers, and nothing crosses without your approval.
How it works
- Connect. Add Myeline as a custom connector in Claude or any MCP client, then sign in and approve the connection. Setup takes three steps.
- AI clients propose. When your AI learns something durable (a preference, a decision, an open loop) it saves it to Myeline. Every save lands in your review queue, staged.
- You approve. Swipe right to make a memory live, or left to retire it with a reason. Nothing reaches your memory any other way.
- Answers show their source. Every search result carries a Source line, so you can check any fact your AI repeats back to you.
- Forgetting takes a reason. A retracted fact stops appearing in answers; the reason stays in your audit log.

Questions
What is Myeline?
Myeline is a memory layer for AI assistants. It connects to Claude, ChatGPT, and any client that speaks the Model Context Protocol (MCP), and stores what your AI learns about you as single facts, each with its source attached. AI clients can only propose memories; nothing goes live until you approve it.
How is Myeline different from an assistant's built-in memory?
Built-in memory belongs to one assistant. Myeline is one memory you control that any MCP client can use, so what one AI learns another can cite. Every fact carries its source, every new memory waits in your review queue, and a retracted fact keeps its reason in an audit log.
Which AI clients work with Myeline?
Claude, ChatGPT, and any MCP client that supports remote servers. Add a custom connector with the address https://cortex.myeline.si/mcp, sign in with your Myeline account, and approve the connection.
Can an AI save a memory without my approval?
No. Every memory an AI client saves lands in your review queue as a staged card. You swipe right to approve it or left to retire it with a reason. No permission a client can hold lets it approve a memory or change billing.
What does Myeline do with my data?
Myeline only receives what your AI client sends through its tools. It never reads your chat history, your client's own memory, or your files. It refuses to store Social Security numbers, bank account and routing numbers, payment card numbers, and passwords or API keys at every setting.
How much does Myeline cost?
The free plan holds up to 200 live facts. At the limit, new memories are refused with a clear message, never silently dropped, and search keeps working. The personal plan is $20 a month and removes the limit; the team plan is $20 a seat a month with a 2-seat minimum. Every plan is on myeline.si/plans.
Can my team share one Myeline memory?
Yes. A team brain is one shared memory that every member's AI reads from and proposes into, at $20 a seat a month with a 2-seat minimum. It is invite-only, admins decide what goes live or gets retired, and each member's personal brain stays private.
Can Myeline keep prompts I reuse?
Yes. Save a prompt or startup script under a handle and Myeline keeps it word for word. Type #handle in ChatGPT, Claude, or any connected AI and it comes back exactly as saved. A prompt an AI saves waits for your approval like any memory.
How do I make Myeline forget something?
Retract the fact with a written reason. It stops appearing in answers immediately, and the reason stays in your audit log. For a full account deletion, email hello@myeline.si.
