A few apps, made carefully.
We'd rather ship a small number of focused tools we use every day than a catalogue of things we don't. Here's what's out now.
MaiD
A focused, native Markdown editor — side-by-side live preview, an outline built from your headings, native Mermaid diagrams drawn in pure Swift, and one-click HTML & PDF export. Sandboxed and offline by design.
- ✓Side-by-side editor and live preview, light or dark
- ✓Mermaid diagrams rendered natively — no web view, no JS engine, no network
- ✓Outline sidebar from your headings; real macOS documents with auto-save & version history
- ✓Export to clean, self-contained HTML and PDF
ChessLLM
Play chess against the large language model of your choice — frontier cloud models via OpenRouter, or entirely offline with LMStudio, llama.cpp, or Ollama. A pure-Swift engine enforces every rule; the model plays the moves, with streaming commentary in the tone you pick.
Columnar
Trello, in your menu bar. View, create, update, and archive boards, lists, and cards without leaving whatever you're working on — real kanban columns with drag-and-drop, checklists, comments, and reactions, behind one global hotkey.
- ✓Boards as kanban columns — drag cards between lists, reorder lists by dragging
- ✓Checklists, comments with emoji reactions, members & real avatars
- ✓⌃⌥T from anywhere; your API key and token live in the macOS Keychain
- ✓Native SwiftUI & AppKit, sandboxed — talks only to the Trello API
swift-mermaid
A pure-Swift Mermaid renderer for Apple platforms. No JavaScript engine, no WKWebView, no network entitlement — for sandboxed apps that need Markdown previews with diagrams. It's what powers MaiD's diagrams.
.package(url: "github.com/australware/swift-mermaid"),
// then render — no web view
let view = MermaidView(
source: "graph LR; A-->B"
