TandemLoop

Get Things Done with AI Agents

Free · In‑App Purchases

A to-do app for you and your AI agent. Plan, organize, and get everything on your plate done—together with your AI agents. TandemLoop is the shared to-do app for people who work with AI agents: You plan and steer, your agent works alongside you—in the same projects and tasks. Organize your tasks in areas and projects, and use your own views to build exactly the overview you want to work with—GTD style, as a kanban board, or your own way. HOW IT WORKS TandemLoop gives you and your AI agents—for example, Claude Code, Cursor, or Codex—a shared foundation for your tasks. All data in TandemLoop—tasks, projects, views, and settings—is stored as Markdown text files in a folder in your iCloud Drive, not in a closed database. That’s why any AI agent can work with it, with no plug-in and no API. TandemLoop gives agents a manual that explains how the system is structured and what they’re allowed to do. No account, no server of our own, no data collection. Your data belongs to you. HOW YOU AND YOUR AGENT WORK WITH TANDEMLOOP You give your agent instructions, and the two of you work together in the same to-do app: • Ask it to complete its tasks. It works through them and attaches the result to each task. • Ask it to process your Inbox. It files the items into your projects and suggests priorities. • Ask it to review your projects, for example for your weekly review. • Ask it to add every open item from your session as tasks in your project. • Ask it to create new views, projects, or areas for you. • Anything only you can do—a sign-up, an approval, a decision—it adds as a task for you. • You decide how independently it works: do the task, prepare a draft first, or ask before acting. • For bigger jobs, you describe the goal, requirements, and acceptance criteria right on the task. • If you want more control at first, turn on proposals: The agent proposes changes, and you approve them. EVERYTHING A GOOD TO-DO APP NEEDS • Areas, folders, projects, milestones, and tasks—sequential or parallel • Inbox, nested tags of any depth, and custom fields • Due dates with times, do dates, defer dates, Waiting For, and reminders • Recurring tasks: daily, weekdays, weekly, monthly, yearly—on a schedule or after completion • Only Next Action for projects and milestones • Views as List, Table, Board, Agenda, Calendar, Multi-View, and Dashboard—with filters, groups, and sorting • Quick Search, undo, drag and drop, and customizable keyboard shortcuts • Themes with your own color scheme CAPTURE ANYWHERE • Mac: system-wide keyboard shortcut, menu bar, and the Add as Task in TandemLoop service • iPhone and iPad: Share menu, Control Center, and Quick Entry • Shortcuts and Siri • Widgets for the Home Screen, Lock Screen, and Mac desktop—check off tasks right in the widget • Notifications with Complete, Later, and Tomorrow actions • Open tasks in Spotlight search ON MAC, IPAD, AND IPHONE Capture on your iPhone on the go, plan and hand off on your iPad, work on your Mac—where your agent works too.
