① App Overview

DeepDo is an unlimited-hierarchy to-do app for task and project management.
Create subtasks within tasks, then add finer tasks inside those to structure complex content freely.

It supports AI-powered structure generation.
Enter ideas, text, or project plans and AI organizes them into hierarchical to-dos—from execution steps to information layout.

Many to-do apps stop at 2–3 levels; DeepDo supports unlimited depth for projects, learning plans, design notes, and checklists in a tree view.

Save, share, and export as PDF. Public, group, and password-protected sharing for personal and team use.
