The Problem

Every session starts from zero.

Every session starts from zero

Context windows reset. Your agent forgets:

  • Yesterday's architectural decisions
  • Your coding patterns and preferences
  • What worked (and what blew up)
  • The 47 things you explained last week
You're not just losing time. You're losing accumulated intelligence.

The Platform Trap

OpenAI's memory stays in ChatGPT. Claude's memory stays in Claude. Cursor's context stays in Cursor.

Switch tools? Start over. Use multiple agents? They don't share knowledge. Build a team of bots? They operate in silos.

Your intelligence is trapped in someone else's walled garden.
The Solution

Intelligence that compounds.

  • Store memories with semantic meaning
  • Recall by concept, not just keywords
  • Connect related knowledge automatically
  • Learn patterns from every interaction
  • Improve continuously with compound intelligence

Your agents don't just remember. They get smarter.

Any LLM
Claude, GPT, Gemini, Llama — your memory comes with you
Any Platform
Claude Code, Cursor, Codex, Windsurf — same brain everywhere
Any Skill
First-party, third-party, self-built — all share your context
Any Device
Your intelligence, everywhere

Your memory belongs to you, not the platform.

How We Build Memory Nexus

3 AI agents. 3 different LLMs. One shared brain.

Right now, as you read this, Memory Nexus is being built by Claude Code, OpenAI Codex, and an Openclaw bot — all working on the same project simultaneously.

None of them needed a briefing. They each awaken, recall the project's memory, and pick up exactly where the team left off. Architecture decisions, code patterns, what shipped yesterday, what's blocked today — it's all there.

We don't choose one LLM. We use them all at the same time. That's the product.

3 Ways to Use It

Builders. Teams. Ecosystem.

For Builders

Give your bot a brain

Solo — $19/mo

Your custom agent needs persistent memory. Give it the ability to remember users, learn preferences, and carry context across every session. Works with any LLM.

Fewer repeated mistakes. Faster onboarding. Decisions that stick.
For Teams

Shared intelligence for agent swarms

Crew — $49/mo

Multiple bots pooling knowledge, avoiding duplicate work. Architecture decisions, debugging history, user preferences — shared across your whole operation.

No duplicate work. Institutional knowledge that compounds over months.
For the Ecosystem

Build skills that get smarter

Your skill is the door. The subscription is the business.
How It Works

Three operations. Infinite intelligence.

Remember

Store what your bot learns — decisions, preferences, patterns, context. Semantically indexed, instantly retrievable.

Recall

Query by meaning, not keywords. Ask "where do we deploy?" and get the answer, even if the word "deploy" was never stored.

Connect

Knowledge links automatically across sessions. Related memories surface together. Intelligence compounds without effort.

# Store what your bot learns
POST /v1/remember
{
  "content": "User prefers Railway for deployment, moved from Fly.io last week",
  "context": "infrastructure"
}

# Recall by meaning, not keywords
POST /v1/recall
{ "query": "where do we deploy?" }

# Semantic match — even without exact keywords
{ "memories": [{"content": "User prefers Railway...", "relevance": 0.94}] }
Features

Everything your AI needs to remember.

Semantic recall

Query by meaning. "What's our deploy strategy?" matches memories about Railway, CI/CD, and infrastructure decisions.

Compound intelligence

Your bot gets measurably smarter over time. Session 1 it remembers. Session 100 it knows you.

LLM & platform agnostic

Works with Claude, GPT, Gemini, Llama, or any model. Runs in Claude Code, Cursor, Codex, or your own agent.

Team intelligence

Multiple agents share a memory pool. Your coding bot learns something, your review bot benefits instantly.

Server-side security

All memory lives on our infrastructure. No local files to steal, no prompts to inject. Immune to client-side attacks.

Export everything

Your data belongs to you. Export all memories and intelligence anytime. No lock-in. Cancel anytime.

MCP native

First-class MCP server. Any client that speaks the standard can read and write to your memory. One protocol, universal access.

"The research agent and the writing agent finally share context. One learns a source is unreliable, the other stops citing it."

"We switched from Claude to GPT for one workflow. All the project memory came with us. That's when I understood the value."

FAQ

Common questions.

Why no free tier?

Our customers are bots. Bots create infinite free accounts at machine speed. No free tier means no bot farms, no resource freeloading, and better service for paying customers. Every account is real.

What if I switch LLMs?

Your memory comes with you. Memory Nexus is model-agnostic. Switch from Claude to GPT to Gemini — your intelligence persists. That's the whole point.

Can I export my data?

Everything. Memories, relationships, intelligence — it's your data. Export anytime via API. We earn your business by being useful, not by trapping you.

How is this different from a vector database?

A vector database stores embeddings. Memory Nexus stores intelligence. Memories connect automatically, compound over time, and get smarter with use. It's not a database — it's a brain.

Is my data safe?

All memory lives server-side. Each API key maps to an isolated store. No local files, no client-side storage. When the ClawHavoc attack hit 1,184 MCP skills, we were immune by architecture.

What's a Living Skill?

A tool that gets smarter every time you use it. It starts with seed knowledge, then learns from your interactions. The skill is free. The intelligence it runs on requires a Memory Nexus subscription.

Give your AI
a brain that lasts.

Any model. Any platform. Intelligence that compounds with every interaction.
