## for OpenAI Codex
Give Codex a Memory
Persistent context for your OpenAI coding agent, across every session.
Every session starts from zero
Without memory, OpenAI Codex forgets everything between sessions.
- —Codex starts fresh every time — no memory of your codebase or past decisions.
- —You spend time re-establishing context instead of shipping code.
- —Project knowledge lives in your head, not somewhere Codex can access it.
- —Long-running projects lose continuity because there's no shared knowledge layer.
Basic Memory changes that
Give OpenAI Codex a persistent, searchable knowledge base it can read and write to.
Persistent context
Codex reads and writes to a knowledge base that carries over between sessions. Decisions, patterns, and project context are always available.
Searchable knowledge
Every conversation builds a searchable knowledge graph. Codex can find relevant context from past sessions in milliseconds.
Plain text you own
Everything is stored as Markdown files on your machine. Read them, edit them, version them with git. No lock-in, no cloud dependency.
Native MCP integration
Codex supports MCP servers natively. Basic Memory connects directly — no wrappers or middleware required.

What users are saying
“Basic memory is the missing 'wow' factor in AI chatbots—now I can't imagine Claude or Claude Code without it.”

“Basic Memory turned my scattered notes and half-finished ideas into something coherent. It remembers what matters and builds on it — so I don't have to start from scratch every time I sit down to work.”

View on GitHubFrequently asked questions
- How do I give Codex persistent memory?
- Connect Basic Memory as an MCP server in your Codex configuration. Codex can then search and update your knowledge base — architecture decisions, conventions, project context — in every session instead of starting cold.
- How is Basic Memory different from AGENTS.md?
- AGENTS.md is a static instruction file; Basic Memory is a living knowledge base. Codex retrieves relevant notes on demand via MCP search rather than loading one fixed file, and it can write new knowledge back. Use AGENTS.md for standing instructions and Basic Memory for everything you learn along the way.
- Can Codex and Claude share the same memory?
- Yes — that is the point of building on MCP. Codex, Claude Code, Cursor, and ChatGPT can all read and write the same Basic Memory knowledge base, so switching tools never means losing context.
