What Is Context Nest?

Context Nest is an open-source CLI that structures your knowledge into versionable vaults. Your AI reads a CLAUDE.md file and instantly understands your project. Think GitHub for knowledge.

Version Control

Git-like history, hash chains, checkpoints for your knowledge

AI-Native

CLAUDE.md bridges your vault to any AI tool — Claude Code, Claude Desktop, Cursor

Inject Anywhere

ctx inject pulls the right context from your vault into any AI conversation

Get Started in 30 Seconds

# Install Context Nest
npm install -g contextnest-cli
# Initialize with a starter
ctx init --starter developer
# Your AI already knows your vault

Works with Claude Code, Claude Desktop (MCP), Cursor, and any AI that reads markdown.

Free forever for local use. No account required.
