One of the most tangible ways that Ziflow helps you deliver your marketing projects faster is by providing a streamlined way to review new and old versions of creative content, side by side.  Ziflow’s Compare mode lets you review any two proof versions side-by-side or as an overlay, with synchronized navigation and automatic change detection. Instead of manually scanning for updates, reviewers can instantly verify whether feedback has been applied before adding comments or approving a proof.

For creative teams, version comparison isn’t just a convenience—it’s how you prevent bad approvals, missed changes, and endless revision cycles. Without a clear way to see exactly what changed between versions, feedback gets duplicated, details slip through, and projects slow down at the worst possible stage.

How to Compare Proof Versions in the Ziflow Proof Viewer:


  1. Open a proof that has multiple versions
  1. Click the Compare icon in the Proof Viewer
  2. Select the two versions you want to review
  3. Choose your preferred view (side-by-side or overlay)

From there, you can zoom, pan, navigate pages, and review both versions in sync..  

Key Compare Mode Features

Auto Compare (Highlight Changes)

Automatically highlights differences between versions so you can quickly spot updates—even subtle ones like text edits, alignment shifts, or color changes.

Side-by-Side and Overlay Views

Switch between structured comparison and layered visual inspection depending on the type of feedback you’re reviewing.

Synchronized Navigation

Zoom, pan, and move between pages in both versions at the same time. You can also unsync views when you need to inspect areas independently.

Comment and Markup Controls

Toggle comments and annotations on or off, and view feedback tied to specific versions without clutter.

Make Decisions in Compare Mode

Approve or reject proofs directly while comparing versions with no need to switch contexts.

Re-sync and Alignment Tools

If your views drift, quickly re-align both versions to stay focused on the same area.

Copy Feedback Across Versions

Reuse comments and markups from previous versions to avoid duplicate work and keep feedback consistent.

Why Compare Mode Matters for Creative Workflows

Without structured version comparison, teams rely on memory and manual scanning to validate changes. That’s where mistakes happen.

Compare mode replaces that guesswork with a clear, visual way to confirm what’s changed—so reviewers can focus on making decisions, not hunting for differences.

What’s Next: AI-Assisted Comparison

Manual comparison is only part of the picture. As creative workflows scale, teams need a faster way to validate changes across large volumes of content.

With ReviewAI, Ziflow is moving toward automated verification—helping teams confirm that required changes have been made without manually reviewing every version. The goal is simple: reduce effort, eliminate human error, and speed up approvals.
