Your project, week by week.

Gantt Maker is a weekly planning board for organizing tasks, people and dependencies.

Create projects, group tasks and adjust dates by dragging the bars. If you enable “Respect dependencies”, delaying a task moves the following tasks when necessary.

Work with an agent on the same board

The plugin lets you read, create and edit plans, and display an interactive Gantt in compatible clients. To use it, install and connect the plugin available in your account, then link the browser using “Connect with OpenAI”.

The connection enables all projects saved in that browser. Keep the original tab open and connected while you work from the chat.

Local projects, settings that suit you

Projects are saved in your browser. Export JSON copies to keep them or take them to another device. The AI connection transmits requests and the necessary data; it does not sync projects between computers.

Explore Settings to choose the first day of the week, dependency behavior and display options. Planning uses complete seven-day weeks.
