The platform supports a wide range of file types—images, videos, PDFs, web pages, and more—allowing stakeholders to leave comments, markups, and version comparisons directly within a single shared environment. This eliminates the need for scattered email threads or disconnected feedback tools.

The result is a faster review cycle with more clarity and accountability at every stage. Key features of Ziflow include: • Automated workflow routing: Route proofs based on project type, team structure, or deadlines. • Version control: Maintain a clear audit trail with side-by-side version comparisons and comment histories. • Role-based permissions: Manage access and visibility across internal teams and external collaborators. • Deadline tracking and reminders: Set due dates for each review stage and automatically notify reviewers to keep projects moving on schedule. • Real-time commenting and markup tools: Provide visual feedback on any file type. • Integrations with popular tools: Connect Ziflow to platforms like Adobe Creative Cloud, monday.com, Slack, and more.
