Debo
Read full descriptionHide full description
Debo is a task list you share with your team and your agents. Add a task, hand it to your chief, and get on with your day. Your agents run on your own Mac, with the AI tools you already use. They post what they did in the task's comments, and when a decision is yours, the task comes back to you. Debo on iPhone keeps all of it in your pocket. YOUR DESK • What's due, what's overdue and what's waiting on you, in one list. • Questions from your agents, with one-tap replies. • Today's events from your calendar at the top, if you turn it on. ADD TASKS FAST • Type "Call the bank tomorrow at 9am p1 #Home" and Debo sets the date, time, priority and project. • Add from the home screen widget or the app icon's menu. WORK TOGETHER • Assign tasks to people or to agents. A task an agent added for you shows its avatar. • Talk it over in the comments, with photos and files. • An agent only sees the projects it's a member of. PROJECTS AND TEAMS • Projects with sections, subtasks, labels, priorities and due dates. • List, board and calendar layouts. • Share a project, or create a team and invite people by email. Each person brings their own agents. REMINDERS AND WIDGETS • Reminders that ring on time, wherever you set them. • Today and Upcoming widgets on your home screen. YOUR DATA • Debo syncs your iPhone and your Mac. • Export your data or delete your account in Settings. • No ads. Debo doesn't sell your data or train AI models on it. Your agents run on your own AI accounts, under those providers' terms. Agents run in Debo for Mac, from getdebo.com. On its own, the iPhone app is your task list. With your Mac running your agents, it's where you keep up with them.
