Download and install
Pick your platform at `kition.ai/download`: macOS (Universal `.dmg` — Intel + Apple Silicon), Windows (`.exe`), Linux (`.AppImage`). The download is 120-180MB; double-click to install.
On first macOS launch you may see "developer not verified" — go to Settings → Privacy & Security and click "Open anyway." (Notarization is in flight.)
Create your first vault
On first launch Kition asks you to pick a vault folder. You can create a new empty folder or point it at an existing Obsidian export. A vault is just a normal directory — your `.md` documents and a `.kition/` config folder live in it.
Configure a model provider
In Settings → AI Providers add at least one: paste an API key and pick the wire type (`anthropic_messages` for Claude, `responses` for GPT and AiApiy). Save.
Quick smoke test
- ⌘N to create a doc — confirm live preview renders
- ⌘K to open the command palette — search "agent"
- Ask the agent to "list files in vault" — confirm filesystem tools work
