Monodesk (https://www.monodesk.com/) offers three project management tools linked in a single interface: calendar, Kanban board and contact/customer database. These three tools can be automated via a chatbot.

The chatbot allows you to define the project, proposes its declination into tasks and subtasks in the Kanban board, declines it in the agenda and creates the contact/customer file or even invoicing. It can help with the writing of emails.
Each conversation is assigned to a project and can be reopened as needed.

A timer assigned to each task is available.
For web and/or creative projects, design or site analysis, proposals for new design, colors, etc.

Free and unlimited beta.
