remem: Local-first memory for Claude Code and OpenAI Codex

Stop re-explaining your project every new coding-agent session.

Language: English | 简体中文

remem automatically captures, distills, searches, and injects engineering memory across Claude Code and OpenAI Codex CLI sessions. Decisions, bug-fix rationale, project patterns, and preferences stay available through hooks, MCP, CLI, and a localhost REST API.

A new Claude Code session recalls the earlier root cause, commit, and open TODO with memory citations and no re-explaining.

What remem gives you

• Automatic session capture and background LLM distillation.
• Project-scoped recall across Claude Code and Codex using one local store.
• Searchable decisions, bug fixes, architecture notes, preferences, and raw session evidence.
• Source attribution, staleness labels, suppression, review queues, and injection audits.
• SQLite with SQLCipher encryption by default for fresh installs.
• MCP, CLI, and authenticated localhost REST access from one Rust runtime.

remem prioritizes memory quality. Automatic capture is the primary path; manual save_memory calls supplement it when a decision needs to be recorded immediately.

Install in five minutes

Homebrew

brew install majiayu000/tap/remem
"$(brew --prefix remem)/bin/remem" install --target codex

Use --target claude for Claude Code. --target all configures every known host, including Cursor where its v1 renderer is supported.

Standalone installer

curl -fsSL https://raw.githubusercontent.com/majiayu000/remem/main/install.sh | env REMEM_NO_CONFIG=1 sh
~/.local/bin/remem install --target codex

npm or Cargo

npm install -g @remem-ai/remem
# or
cargo install remem-ai --bin remem

remem install --target codex

Codex installation, detection, doctor, uninstall, transcript scanning and default native-memory import all honor CODEX_HOME; the default is ~/.codex. Set it to an absolute directory before running these commands to select another Codex profile. Empty or relative overrides fail visibly before installation writes. Unrelated profile files stay untouched.

GitHub Releases: prebuilt binaries for macOS and Linux on x64/arm64, with published checksums. Use one canonical remem executable on PATH; remem doctor warns when hooks and terminals resolve different copies.

For channel-specific upgrades, platform boundaries, PATH drift, and manual install notes, read the installation and upgrade guide. The broader documentation guide links plugin and operational material.

Verify the installation

Restart the selected coding agent, then run:

remem doctor
remem status
remem search "last decision"

A healthy Claude Code or Codex installation injects relevant project memory at SessionStart and queues durable session distillation at Stop. Codex also uses UserPromptSubmit to capture each prompt and surface compact optional memory candidates. remem doctor checks the schema, encryption key, database, hooks, MCP registration, worker, and common install-path drift. Its diagnostics do not create the data directory or write or rotate log files; findings and stderr warnings remain visible, and existing log health is inspected.

Repository contributors can verify duplicate SessionStart suppression with the isolated executable smoke fixture.
