GAIA vs Lifestack
Lifestack is an energy-aware AI planner that reads sleep and recovery from wearables and schedules tasks, meals and rest around your focus. GAIA is a personal assistant that works across your email, calendar, tasks and other tools.
Lifestack, from DeMind Inc., plans your day around your body. It reads sleep, recovery and activity from Apple Health, Oura, WHOOP, Garmin and Fitbit, predicts when your focus will peak and time-blocks tasks from your calendar and to-do list into those windows, along with meals and rest. It works with Google Calendar, Outlook, Todoist and Trello and is aimed at people who want structure without burnout, including people with ADHD. GAIA does not read wearable data. It handles the work that fills the day: triaging Gmail and Outlook, drafting replies, managing your calendar and tasks, and running workflows triggered by your tools, from chat apps, the web and the desktop.
