GAIA vs Things 3
Things 3 is a beautifully crafted GTD task manager exclusive to the Apple ecosystem. GAIA goes further by adding proactive AI intelligence, cross-platform access, and deep integration across your entire digital workflow.
Things 3 from Cultured Code is widely regarded as the gold standard of Apple-native task managers. Its clean design, thoughtful GTD structure with Areas and Projects, and tight OS integration have earned it a dedicated following. But Things 3 is a task manager, not an AI assistant. It requires you to do all the thinking: capturing tasks, setting deadlines, and deciding what to act on. GAIA takes a fundamentally different approach. Rather than giving you a beautiful place to store your todos, GAIA actively creates them from your emails, connects them to your calendar, and executes multi-step workflows on your behalf, on every platform you use.
