Persistent memory for AI coding agents

Your AI coding agent,
finally remembers.

MemoryOS gives Claude Code, Cursor, and any AI coding assistant a real memory of your codebase — so it stops re-reading everything from scratch every time you ask it something.

MemoryOS — persistent memory for AI coding agents

The problem

Every AI coding tool today is amnesiac.

Cursor, Claude Code, Copilot, Devin — each new session starts from zero. Your agent has no memory of the decisions it made yesterday, no sense of what matters in your codebase, and no way to work alongside teammates or other agents without stepping on each other.

— You re-explain the same architecture and conventions over and over

— You can't tell why your agent made a decision, or what it noticed but ignored

— Multiple agents (or you and an agent) working on the same repo collide

— Your agent burns tokens reading whole files instead of the few lines that matter

What you get

A memory that gets smarter every session.

Instant context

Your agent gets exactly the code it needs for the task at hand — not your whole repo. Faster answers, lower bills.

Remembers what matters

The core parts of your codebase stay front-of-mind. Recent changes surface automatically when they're relevant.

Learns your codebase over time

The more you use it, the better it gets at knowing what to bring up for a given task.

Works with your tools

Claude Code, Cursor, Windsurf, Zed, or anything that speaks MCP — no lock-in, no rewrites.

Built for teams

Multiple agents (and people) can work on the same project without overwriting each other's context.

Private by default

Only the structure of your code — not your actual source — ever leaves your machine, unless you choose otherwise.

Why it matters

Less waiting. Fewer tokens. Better answers.
