Trello is a project management tool that uses a visual approach to keep you organized. Imagine a digital bulletin board where you can create boards for different projects. Each board has lists, which could be stages like To Do, In Progress, and Done. You can then add cards to represent individual tasks and move them between lists as you work on them. Trello also allows you to assign tasks to team members, set deadlines, attach files, and create checklists within cards. This makes it a great tool for both individuals and teams to collaborate and stay on track with their projects.
