ClickUp

ClickUp is an AI-driven project management platform. In 2026, its ClickUp Brain connects projects, documents, conversations, and data, providing a global AI assistant. ClickUp positions itself as "one app to replace them all"—integrating task management, docs, whiteboards, chat, and goal management. Core features include task and project management (multiple views: list, board, Gantt, calendar), ClickUp Docs, Whiteboards, ClickUp Brain (AI assistant that summarizes project status, generates tasks, answers workspace questions), and Automations. Its hierarchy (Space → Folder → List → Task) suits complex project management. The free tier provides 100MB storage; Unlimited is $7/user/mo; Business is $12/user/mo (includes AI). For startup teams needing all-in-one project management, ClickUp is more project-focused than Notion and more comprehensive than Asana. However, the feature abundance creates a steep learning curve.
