Your Knowledge,
Never Lost
External context management for AI coding assistants. A two-tier documentation system that persists your knowledge across every session.

AI assistants forget
everything between sessions.
Every new conversation starts from zero. Your architecture decisions, bug fixes, project patterns — all gone. You repeat yourself endlessly.
Constant Repetition
You explain the same project structure, patterns, and decisions in every session. Time wasted, context lost.
Knowledge Vanishes
Bug fixes, architectural decisions, gotchas discovered — none of it carries over. The next session is a blank slate.
No Continuity
Multi-session projects lose coherence. Each AI session makes different assumptions with no shared memory.
Two-tier vault.
Infinite memory.
ContextVault organizes knowledge into two layers — global patterns that follow you everywhere, and project-specific docs that stay where they belong.
Global Vault
- Cross-project knowledge
- Reusable patterns & best practices
- Tool configurations & preferences
- Available in ALL your projects
Project Vault
- Project-specific architecture
- Local configs & decisions
- Codebase-specific patterns
- Stays with THIS project only
Built for developers
who ship fast.
Smart Hooks
Automatic reminders when you've done significant work without documenting. Configurable: light, balanced, or strict.
Auto-Bootstrap
Run /ctx-bootstrap on any new project. Scans your codebase and generates architecture + feature docs instantly.
Session Handoffs
End every session with /ctx-handoff. The next session picks up exactly where you left off.
Smart Dedup
Never create duplicate docs. ContextVault searches by exact terms, synonyms, and related concepts before creating.
23 Commands
Purpose-built commands for every workflow: documenting bugs, decisions, plans, code snippets, and explorations. Slash commands or MCP tools.
MCP Protocol
Works with any MCP-compatible AI tool: Cursor, Windsurf, OpenCode, Cline, Continue, Copilot CLI & more.
Size Guards
Hard limits built in: 100 lines per doc, 50 entries per index, 15-word summaries. Lean context, always.
Unified Documentation
One command does it all: /ctx-doc type=learning|intel|snippet. Learnings, exploration findings, code snippets — streamlined.
Curation Review
Run /ctx-review weekly. Finds stale docs, suggests merges, identifies archive candidates. Keep your vault lean.
Code-Drift Detection
/ctx-health detects when docs reference files or lines that no longer exist. Stay synced with your codebase.
Three steps to
permanent context.
Install
One command. Bash installer for Claude Code, or npx contextvault-mcp for any AI tool. macOS, Linux, Windows.
Work
Use your AI coding tool normally. Smart reminders nudge you to document at natural milestones — not mid-thought.
Remember
Next session loads your vault index automatically. Architecture, decisions, gotchas — all there. Zero repetition.
A command for every moment.
