A drop zone for the markdown documents your AI assistant writes. MD Inbox watches a folder in iCloud Drive on your Mac. When Claude, ChatGPT, Cursor, or any other AI tool saves a markdown file there — a plan, spec, code review, design doc, meeting notes — it appears on your iPhone within seconds. Read it on the go, pin the ones that matter, delete the rest. HOW IT WORKS 1. Pick any folder in iCloud Drive as your inbox. 2. Copy a short prompt into your AI agent's system prompt. 3. From now on, finished documents your agent produces show up here. FEATURES • Live iCloud sync — files appear seconds after your agent saves them • Date-grouped sidebar: Pinned, Today, Yesterday, This Week, This Month, Older • Swipe to delete, tap to pin, multi-select for batch cleanup • Auto-delete after a configurable threshold to keep the inbox tidy • Pinned and read state sync between devices via iCloud • Native markdown rendering with code blocks, tables, and images • Share extension — send markdown from any app THREE BUILT-IN AGENT PRESETS • Plans & Specs — agent auto-saves substantial deliverables • On-Demand — agent saves only when you ask • Quick Captures — short, timestamped notes No account, no server — your files live in your own iCloud Drive.
