One shared brain for your entire AI stack
Every AI you use.
One shared memory.
Write your identity, projects, and decisions once. Every AI tool reads it on start. Every tool writes back what it learns. Five-minute setup.

Claude doesn't know what Cursor learned. Manus doesn't know your tech stack. Every session starts from zero. You're the only one carrying context between tools.
Every tool, every time
“Can you tell me about your project?”
“What framework are you using?”
“What are you building?”
“What's the API endpoint?”
With MemoryKey
“Based on your Next.js + Clerk setup, here's the auth middleware...”
“I see the Neon DB schema. Adding the migration for the new table...”
“Your positioning vs Zenity is strong. Here's the updated landscape...”
“Triggering the pipeline with your API key from the config...”
Set up in five minutes.
Three steps to a shared brain that grows with every AI interaction.
01
Import or write your context
Copy a prompt into any AI you already use — it summarizes everything about you. Paste it in. Done in two minutes, not twenty.
02
Connect your tools
Generate an API key, paste the snippet. Cursor, Claude (MCP), Windsurf, n8n, Manus — any tool, 30 seconds.
03
Everything stays in sync
Every AI reads your context before responding. Every AI writes back what it learns. One memory, always current.
Watch it work.
Claude reads your context via MCP, responds with full knowledge, and stores what it learns — automatically.
Platform memory is siloed. MemoryKey is shared.
ChatGPT Memory
Only remembers what you tell ChatGPT. Invisible to Cursor, Claude, and everything else you use.
Claude Memory
Only remembers what you tell Claude. Your Cursor agent, n8n workflows, and other tools start from zero.
MemoryKey
One shared context across every tool. Claude learns it, Cursor knows it. Write once, available everywhere.
Built for how you actually work.
One folder per client, every tool on-brand.
The problem
Your designers use Cursor, your strategists use Claude, your automations run in n8n. Every tool asks the same questions about the same client. Brand voice, tech stack, past decisions — scattered across chat histories.
With MemoryKey
Create a MemoryKey folder per client. Every tool reads the same brief, tone guide, and project history. When one agent learns something, the others know it instantly.

n8nManusNative MCP server.
Works everywhere MCP works.
MemoryKey ships as an MCP server — the protocol Claude, Cursor, Windsurf, and a growing ecosystem already support. No SDK. No framework dependency. Connect in 30 seconds.

}I use Claude Code, Base44 Agents, Manus, Gemini, ChatGPT, Kiro, and probably a few more I forgot. Sometimes all in the same day. None of them know what the others know. I'm the only one carrying context across my own AI stack. So I built MemoryKey — one shared brain for all of them.
Built for trust.
MemoryKey Cloud or your own database
By default, your data is encrypted on MemoryKey Cloud. Want full control? Bring your own PostgreSQL — your memory, history, audit logs, and files live entirely on your infrastructure.
256-bit encrypted
Your data is never stored in plaintext. Every access is logged.
Full audit trail
Every read and write logged with agent name and timestamp.
Scoped API keys
Read-only or read+write per agent. Revoke any time.
AI synthesis layer
The Brain merges updates intelligently. No overwrites, no conflicts.
