Visual Feedback
With Assentia's visual feedback feature, clients can click anywhere on your live site to pin comments. This eliminates the need for lengthy email threads or Slack messages filled with vague references. Each feedback item is captured with automatic screenshots and context, making it crystal clear what changes are being requested. This streamlined process reduces confusion and enhances collaboration between clients and creators.
One-Click Scope Approval
The one-click scope approval feature allows you to send a clean approval link to your clients before commencing work. Clients can quickly approve the project scope with a single click, ensuring that both parties are aligned on what is included in the project. This professional sign-off process not only boosts transparency but also minimizes potential disputes regarding project deliverables.

Scope Protection Mechanism
The scope protection mechanism ensures that every piece of feedback is checked against the approved project scope.
