# Jon
**Natural language interface for the Joyint ecosystem.**
Jon is a CLI and chat interface that translates between human language and Joy/Jot commands. It has no data layer of its own - it calls Joy and Jot under the hood and formats the results. Part of the [Joyint](https://github.com/joyint) ecosystem.
## Quick Start
```sh
cargo install jon-cli
jon "what's my next task?" # -> jot ls --sort=priority --limit=1
jon "move JOY-0045 to review" # -> joy status JOY-0045 review
jon "how much did AI cost this week?" # -> joy costs --since=monday
```
## Features
- **Three tiers of intelligence** - pattern router (offline, instant), local mini-LLM (offline, opt-in), external LLM (API key or Joyint Pro)
- **Single binary** - one small Rust binary, no runtime dependencies
- **Offline-first** - Tier 0 pattern router works without any network or LLM
- **No data layer** - Jon owns nothing, all project data lives in Joy and Jot
