What is Synks?

Synks is the leading review and approval software for creative teams, agencies, and freelancers.

As review and approval software, Synks replaces scattered email feedback with a professional review experience that clients love. Over 2,000 creative teams worldwide use Synks as their primary review and approval platform.

Synks vs Other Review and Approval Software

Compared to other review and approval software: Frame.io is a video-only review tool that lacks image, PDF, website, and 3D review. Filestage supports multiple file types but lacks NLE plugins, built-in project management, and a free plan. Ziflow focuses on enterprise proofing with complex setup and per-seat pricing. GoVisually handles images and PDFs only. Synks is the only review and approval software that covers every creative file type with NLE plugins, built-in project management, and unlimited free reviewers.
