Tandem is a task management tool built around a simple idea: you shouldn't have to think about how to organize your tasks — just tell Tandem what you need to get done, and it figures out the rest. ## How it works Instead of filling out forms, you have a conversation. Type what you need to do, and Tandem's AI asks the right questions, builds a plan with subtasks, and saves everything structured and ready to go. Once your tasks are in, Tandem helps you decide what to actually work on today — surfacing must-dos, flagging deadlines, and suggesting what to tackle next based on your priorities. ## Key concepts **Tasks** are the core unit. Every task has a title, priority, optional deadline, category, tags, and subtasks. Most of this gets filled in automatically through conversation. **Projects** group related tasks together. Each project can have its own set of categories to keep things organized. **Today** is Tandem's daily plan — a curated list of what to focus on right now, generated fresh each day. **The CLI** lets you manage everything from your terminal, including a full AI-assisted task creation flow. ## Next steps Create your account and add your first task Install the Tandem CLI and manage tasks from your terminal
