What Gantter is

Gantter is cloud-based project-management and scheduling software for monitoring progress and sharing project files. Plan Boards let several people move tasks with drag and drop, while the interactive Gantt chart keeps schedule data synchronized in real time. The system supports task dependencies, milestones, critical-path planning, baselines, resource management, and workload views. My Workspace summarizes task status across projects, and analytics reports can use one schedule or multiple schedules. Brena, the AI Planning Assistant, recommends project-plan options. Gantter supports simultaneous editing in Google and cloud versions and connects with Google Drive, Calendar, sharing, comments, and Hangouts. It reads and writes Microsoft Project .mpp files and opens or saves Oracle P6 files; Microsoft Project exports are XML. The service runs on the web and as an extension, supports 23 languages, and offers ongoing real-person support. There is no mobile app, though mobile Chrome access and Google Calendar syncing are available.

Verdict

Gantter combines visual planning, detailed scheduling controls, collaboration, analytics, and broad file compatibility. Its paid model and lack of a dedicated mobile app are the main limits.
