Give your AI assistant a persistent memory.
Stop repeating yourself. Start building smarter.
When you use an AI assistant to build things, context gets lost (across days, repos, chats). You end up re-explaining background, repeating decisions, and sometimes the assistant continues with the wrong assumptions.
OpenContext is a lightweight personal context / knowledge store for AI assistants (Agents) and coding tools like Cursor / Claude Code / Codex. Write down important project context as documents, and let your assistant "load history first, then act; ship, then persist".
Skills-first support: oc init generates user-level skills (Cursor/Claude Code/Codex) plus slash commands (Cursor/Claude Code), so agents can load, search, create, and iterate your context with one command.
| Before OpenContext | After OpenContext |
|---|---|
| 📂 Hard to share context across repos/sessions | ✅ Global context library works across all projects |
| 🤷 Your ideas can't be quickly perceived by Agent | ✅ Agent loads your background & decisions automatically |
| 🔒 Existing knowledge can't be operated by Coding Agent | ✅ Agent can directly read/write your knowledge base |
ocCLI — manage a globalcontexts/library (folders/docs, manifests, search)- MCP Server — so Cursor/Claude Code/Codex/Agents can call OpenContext as tools
- Skills + Slash Commands — user-level skills for Cursor/Claude Code/Codex and slash commands for Cursor/Claude Code (generated by
oc init) - Desktop App — manage/search/edit contexts with a native UI
- Web UI — browse/edit contexts locally (no install required)
npm install -g @aicontextlab/cli| Path | Best For | Get Started |
|---|---|---|
| 🖥️ Desktop App | Visual users who want a native UI | Download from Releases |
| ⌨️ CLI + Tools | Developers using Cursor/Claude Code/Codex/AI agents | npm install -g @aicontextlab/cli && oc init |
| 🔧 CLI Only | Power users, automation | npm install -g @aicontextlab/cli |
# 1. Install
npm install -g @aicontextlab/cli
# 2. Initialize (prompts for tool setup; defaults to all)
cd your-project
oc init
# 3. Use slash commands (Cursor + Claude Code)
# /opencontext-context — load background before working
# /opencontext-search — find relevant docs
# /opencontext-create — create a new doc
# /opencontext-iterate — persist what you learned
# Tip: non-interactive installs can use --tools cursor,claude,codex or --no-claude/--no-cursor/--no-codex
#
# Installed by oc init:
# - Cursor: ~/.cursor/commands
# - Claude Code: ~/.claude/commands (or $CLAUDE_CONFIG_DIR/commands)
# Skills (wrapped from slash commands):
# - Cursor: ~/.cursor/skills/opencontext-*/SKILL.md
# - Claude Code: ~/.claude/skills/opencontext-*/SKILL.md (or $CLAUDE_CONFIG_DIR/skills)
# - Codex: ~/.codex/skills/opencontext-*/SKILL.md (or $CODEX_HOME/skills)
#
# 4. MCP config is user-level (Cursor/Claude Code/Codex)
# - Cursor: ~/.cursor/mcp.json
# - Claude Code: ~/.claude/mcp.json (or $CLAUDE_CONFIG_DIR/mcp.json)
# - Codex: ~/.codex/mcp.json (or $CODEX_HOME/mcp.json)📖 For detailed usage guide, search configuration, and FAQ, visit the Website.
