Overview
Approval Studio
Approval Studio is a dedicated visual review tool that simplifies how you get feedback on creative assets. Instead of chasing approvals through messy email threads, you can invite clients and team members to annotate designs, PDFs, and videos directly in their browser. It eliminates communication gaps by providing four distinct comparison modes to track changes between versions, ensuring no detail is missed during the revision process.
You can manage your entire creative workflow from a centralized dashboard that tracks the status of every project in real-time. Whether you are an independent designer or part of a high-volume creative agency, the platform helps you reduce the number of revision rounds and get final sign-off faster. It focuses on making the review experience professional for your clients while keeping your internal team organized and accountable.

The platform offers a robust free version for small teams and scales into advanced enterprise tiers with sophisticated security and compliance features.
