About

Kyle

Read full description

Kyle is a shared notebook for you and your AI. Write notes and manage tasks in a fast, native app — and connect any AI that speaks MCP so it can read, write, search, and organize right alongside you. NEW IN 2.1 — CONNECT YOUR AI IN ONE PASTE Sign in with Apple once. Pick your AI. Paste one URL. Kyle watches for the connection and tells you the moment it's made — no guessing whether it worked. • Claude signs in with your Apple ID; there's no key to copy • Cursor, Windsurf, VS Code, and any MCP client get a private URL — one click on the Mac • Kyle on a second device? Sign in and your notes are already there, even without iCloud Keychain BOARDS AND TASKS Your notes have company: tasks, and both live together on boards. • Boards are places. Swipe between them and the title tracks your finger. Each board has its own tint. Kyle reopens on the board you left. • Tasks take one tap to close. No stages, no ceremony. When something matters more, mark it priority from a long press. • The Priority board gathers your priority tasks from every board into one place — it's always first, so what matters most is one swipe away. • Link a task to the note it came from, so the reasoning and the work stay together. • On iPad and Mac, boards stand side by side in columns. On Mac, notes open in their own windows. YOUR AI WORKS HERE TOO Open Connect to AI, choose Claude, Claude Code, Cursor, Windsurf, VS Code, or any MCP client, and follow three steps written for that client. Your AI can: • Save notes and create tasks while you talk • Search everything you've written • Update meeting notes, complete tasks, tag and file things on the right board • Build HTML dashboards you can open right in the app Ask for a summary at the end of a conversation and it's on your phone before you stand up. THEN TEACH IT TO USE KYLE Connecting lets your AI reach Kyle. Kyle also gives you the standing instruction to paste into your assistant, so it searches your notes before starting work and files what matters without being asked. Copy it from Connect to AI, or any time from Settings. TRULY OFFLINE Boards, notes, and tasks load from a local cache — a cold launch on a plane still shows your work. Create and edit offline; everything syncs when you're back. If an edit collides with a change from another device or your AI, Kyle keeps both versions. Nothing is ever silently overwritten. A REAL MARKDOWN EDITOR Headings, lists, task lists, tables, code blocks, blockquotes — written in plain text, rendered beautifully. Import text, Markdown, and HTML files. Export notes as HTML. BUILT INTO APPLE'S ECOSYSTEM Your notes and tasks are available to Siri, Spotlight, and Apple Intelligence. Create a note by voice, find anything from Spotlight, and use App Shortcuts without opening the app. PRIVATE BY DESIGN Sign in with Apple — Hide My Email works — or skip and start writing; Kyle makes you an account either way, with no password. Your notes sync through your private account and are never used for training. You're asked once, plainly, what connecting an AI shares, and you can delete the account from Settings at any time. FREE TO START The whole app is free: notes, tasks, boards, the markdown editor, sync, offline, Siri and Spotlight, and Read Aloud with the best voice on your device. Kyle Pro adds one thing — the AI connection. Every account starts with a 60-day trial of it. Works with Claude (iPhone, Desktop, Web), Claude Code, Cursor, Windsurf, and any MCP client. KYLE PRO Kyle Pro is an auto-renewable subscription, offered monthly or yearly. Payment is charged to your Apple Account at confirmation of purchase. The subscription renews automatically unless it is cancelled at least 24 hours before the end of the current period. Manage or cancel anytime in your Apple Account settings.
