Plutio vs Copilot (Assembly): which fits your business in 2026?

Plutio is a genuine project management tool with Kanban and Gantt views, time tracking, and metered AI, starting at $19/mo. Copilot (now rebranded Assembly) is a client-communication and billing hub starting at $39/mo for a single internal user, with no real project delivery views. Teams that need to manage internal work, not just client messaging, get more from Plutio — and more still from a platform built for both.
