Trello is a visual work management platform that helps individuals and teams organize tasks, projects, and workflows using a flexible board-based system. The platform uses cards, lists, and boards to provide an intuitive way to track work progress and collaborate with team members.

The platform features three core components: Inbox for capturing tasks from various sources including email and messaging apps, Boards for organizing work visually from to-do to completion, and Planner for scheduling tasks on a calendar. Trello includes automation capabilities through Butler, allowing teams to automate repetitive tasks and workflows without coding. The platform integrates with numerous productivity tools through Power-Ups, enabling teams to connect their existing software ecosystem.

Trello supports various team types including marketing teams for campaign management, product managers for roadmap planning, engineering teams for agile development, design teams for creative workflows, and remote teams for distributed collaboration. The platform offers multiple views including board, timeline, calendar, and dashboard perspectives to visualize work in different ways.

Teams can customize boards with custom fields, advanced checklists, and labels to match their specific workflows. Card mirroring allows users to view tasks from multiple boards in a single location. The platform provides templates from industry leaders and the Trello community to help teams get started quickly.
