Team members and clients can reply in threads and attach supporting files, keeping all discussion centralized and clear.

Multi-Breakpoint Testing

Proofapp automatically captures and presents screenshots of your website at both desktop and mobile breakpoints. This allows for comprehensive review across different device views in one place, ensuring design and functionality issues are caught no matter how a user accesses the site.

Real-time Collaboration & Dashboard

See comments from your team and clients as they are posted, in real-time. A central dashboard organizes all feedback across projects, allowing you to track, reply to, and resolve comments efficiently. This ensures everyone is aligned and prevents feedback from getting lost in scattered communication channels.

Art teachers can leverage CBE to design educational coloring books and resources that enhance student creativity. The tool’s local processing ensures that all materials are easily accessible and customizable.
