AI Memory Server
Your AI has memory. But not a brain.
Claude, ChatGPT, and Cursor remember things — but only snippets. Isolated, flat, without context. Nex Memory gives your AI real long-term memory: structured, connected, across all your tools. It learns, detects contradictions, and cleans up after itself.
The real problem
Built-in memory is a Post-it note. Not a brain.
Yes, your AI has memory now. But let's be honest: ChatGPT stores a few sentences. Claude remembers project notes. Cursor knows your rules. Sounds great — until you realize none of these tools talk to each other. Your Claude knowledge doesn't exist in Cursor. Your ChatGPT context vanishes when you switch windows. And when something changes? No tool catches the contradiction. You're still the only connection between your AI tools — and you keep repeating yourself.
What changes
Before. After.
You explain your project setup to your AI for the third time.
Your AI knows your project, your team, your decisions — from the very first session.
You switch from Claude to Cursor and start from scratch.
Same knowledge in every tool. Claude, Cursor, VS Code — one shared knowledge base.
Your AI suggests a solution you rejected last week.
"We rejected that because..." — your AI remembers decisions and reasons.
After 3 months, your AI still makes the same mistakes.
Mistakes are stored as learnings. Same mistake? Never again.
You spend 20 minutes searching for info you discussed "at some point" with ChatGPT.
Semantic search across everything: facts, people, projects, decisions — in seconds.

53 MCP ToolsWhat Nex Memory does
Not just notes. A second brain.
Built-in memory stores sentences. Nex Memory builds a knowledge network — with structure, context, and intelligence.
Learns proactively
Your AI stores facts, decisions, and mistakes automatically — you don't have to do anything. After every session, it knows more than before.
Knowledge Graph
People, projects, tools, concepts — all as connected entities. Your AI understands relationships, not just keywords. "Who works on Project X?" — one question, one answer.
Detects contradictions
Last week the budget was 50k, this week you say 80k. Nex Memory catches the conflict and asks — instead of silently keeping the old info.
Works everywhere
Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed — one URL, and all share the same memory. No copy-pasting between tools.
Cleans up after itself
Unimportant knowledge fades over time, important facts persist. Like real memory — no clutter, no manual cleanup, no "memory full".
Import your history
Bring your existing knowledge: import conversations from ChatGPT, Claude, and Gemini. Your new memory doesn't start from zero.
Multi-Agent support
Multiple AI agents, one memory. Each agent has its own scope, but all access the shared knowledge base. Perfect for teams and automations.
