the file review part is the actual differentiator - most PM tools bolt file comments on as an afterthought, but here you can review images, video, audio, PDFs and even 3D models/sprite sheets in the same place tasks live, and feedback turns straight into a task linked back to the review. the client-approval portal is also a smart touch for agency work, since it means you're not emailing a client a screen recording and hoping they reply in the right thread.
