A persistent, biologically-inspired memory system for AI agents. Hebbian learning. Energy decay. Semantic retrieval. One SQLite file. No cloud. No vendor lock-in.

Every memory weighs the same forever. No relevance, no decay, no learning. Just an ever-growing pile of embeddings.
Memories have energy that decays over time. Unused memories sink into deep storage. Important memories stay active through natural recall patterns.
Search returns results. That's it. No association, no reinforcement, no emergent structure.
Memories recalled together form associations automatically. Your knowledge graph builds itself through use — neurons that fire together wire together.
Your memories live on someone else's server. Latency, vendor lock-in, privacy concerns, monthly API bills.
One file. Your disk. Zero network calls for memory operations. Back it up, move it, own it. The SQLite of AI memory.
Persona, traits, values, preferences, relationships, instructions. Always loaded, always available. The bedrock that everything else is built on.
Authoritative external knowledge — indexed, searchable, citable. Immutable source documents with a personal annotation layer on top. Full-text FTS5 search with APA 7 citations.
Episodic and semantic memories with energy-based lifecycle. Hebbian association, vector similarity search, and four decay states. Memories never delete — they sink, and can always be resurrected.
Memoryco runs as an MCP server. Add it to Claude Desktop, Cursor, your custom agent — anything that speaks the Model Context Protocol gets persistent memory in one config line.
Your AI stores what it learns, recalls what's relevant, and builds associations through natural conversation. No code changes to your agent. Just memory.
Supports stdio and network transports. SQLite for personal use, Postgres for teams. Same API, same cognitive model.
Create, search, recall, delete, associate. Semantic vector search finds memories by meaning, not just keywords. Batch operations for efficiency.
Persistent persona, traits, values, preferences, relationships. Always loaded, never decays. The foundation every response builds on.
Index authoritative documents with full-text search. APA 7 citations. Immutable sources with personal annotation layers. Pro & Business tiers.
Task-specific context guides loaded whole into working memory. Style guides, review checklists, documentation standards. Apply consistently across sessions.
Lightweight multi-step task tracking. Create plans, add steps, mark completion. Transient working documents that keep complex tasks on track.
Adjust decay rate, Hebbian learning rate, recall strength, propagation damping. Every cognitive parameter is a knob you can turn.
We believe your AI's memory should live on your hardware, decay like biological memory, and learn through the same associative patterns that make human cognition powerful.
No cloud. No API bills. No data harvesting. Just a single SQLite file that gets smarter every time you use it.
Your brain.db lives on your disk. Back it up with cp. Move it with scp. It's a file, not a service.
Unused memories fade naturally. What remains is what matters. This is how real memory works — and it's how AI memory should too.
Hebbian learning means your knowledge graph emerges from actual usage patterns. No manual tagging, no taxonomy design. Just recall.
Archived memories aren't deleted. They sink into cold storage and can be resurrected with a single recall. Every experience is recoverable.
Free for personal use. No credit card. No cloud account. Just memory.
