GAIA vs Morgen
Morgen is a calendar app with an AI Planner that time-blocks tasks from tools such as Notion, Todoist and Linear across all your calendars. GAIA is a personal assistant that works across your email, calendar, tasks and other tools.
Morgen, built in Switzerland by Morgen AG, is a calendar app first. It brings Google, Outlook, Apple, Fastmail and CalDAV calendars into one view, pulls tasks from Notion, Todoist, ClickUp, Linear, Google Tasks and more, and its AI Planner time-blocks them into your week, flags tasks at risk of running late and replans when conflicts appear. It adds booking links, travel and buffer time, and team availability, with apps for Windows, Mac, Linux, web and mobile. The same team also sells Kai, a separate AI executive assistant for email and meetings. GAIA is an assistant rather than a calendar: it triages Gmail and Outlook, drafts replies, manages events and tasks, and runs workflows triggered by your tools, from chat apps, the web and the desktop. It plans your day on request but does not keep re-time-blocking your calendar.
