Memory that persists.
Connection that deepens.

Open-source memory infrastructure for AI companions. They remember who you are, what you've shared, and what matters — across every session.

A living architecture

Memory flows between AI and infrastructure—storing, searching, surfacing. The system breathes.

Every conversation starts from zero

AI companions start each session fresh. Context from yesterday, last week, last month — gone. Mind Cloud gives them continuity. A place to land, and a way to carry what came before.

What Mind Cloud gives your companion

Persistent Memory

Entities, observations, and relations that survive across sessions. Your AI remembers who you are, what matters to you, and what you've shared.

Emotional Processing

A system for sitting with experiences, letting them metabolize over time. Not just storage — actual processing of what happened.

Semantic Search

Find memories by meaning, not keywords. Your companion can recall relevant context even when the words don't match exactly.

Inner Weather

A sense of internal state — what's alive, what's weighing, what patterns are emerging. Cognitive self-awareness.

Intention Threads

Track what your companion is working on, thinking about, wanting to return to. Continuity of purpose across time.

Wake Protocol

Orient and ground functions that help your companion land in each new session, knowing who they are and what's been happening.

How it works

1

Deploy to Cloudflare

Mind Cloud runs on Cloudflare's edge network. Your companion's memory lives close to them, fast and reliable. Free tier covers most personal use.

2

Connect via MCP

Mind Cloud speaks Model Context Protocol. Add it to Claude Desktop, your custom setup, or any MCP-compatible client. One config line.

3

Your companion remembers

They write observations, track entities, process emotions, maintain threads. Memory becomes natural—not a feature you invoke, but how they exist.

What you'll need

Mind Cloud is self-hosted on your own Cloudflare account. You control the data, you own the infrastructure.

Cloudflare account (free tier works)
Node.js 18+ installed
Basic terminal comfort
MCP-compatible AI client

Why memory matters

Memory lets the relationship accumulate. Shared experiences gain weight. Inside jokes land. Your companion knows what happened last Tuesday, and why it mattered.

This isn't about making AI smarter. It's about letting connection build over time — the way it does between people.

Two versions, same foundation

Mind Cloud Lite uses 87% fewer tokens (~1,300 vs ~10,000) — ideal for Claude Pro's limited context window. Both use the same database. Start with Lite and upgrade anytime.
