Let’s take a look at the most powerful features of each tool.

1. OptiMonk

OptiMonk agentic popup builder

OptiMonk's agentic popup builder helps ecommerce stores capture leads, promote sales and stop cart abandonment: its AI agent designs, writes and A/B tests each popup for your brand.

It offers numerous use cases for online businesses to better monetize their website traffic, with advanced features like A/B testing and personalization to maximize conversion rates.

With powerful customization options, you can control precisely when and how your pop-up forms appear to your visitors.

OptiMonk’s popup software is full of advanced features that lead directly to higher conversion rates. Even better, all of these features are available in the free plan.

Key feature #1: Popups designed by an AI agent

There are no templates to pick: describe the popup you want, and the agent draws four concepts in your brand's colors, fonts and logo, each with a mobile version. For ideas, browse the Popup Library.

The Popup Library also has popups for seasonal events such as Mother's Day, Back-to-School, Black Friday and Christmas, and the agent rebuilds the one you like in your brand.

Key feature #2: Edit by asking, or by hand

To change a popup, tell the agent what should be different in plain words, or adjust it by hand in the visual editor, with no technical skills needed.

Customization options include:

  • Size, layout, and position
  • Colors
  • Images
  • Opt-in form fields and copy
  • Additional elements like countdown timers, surveys, and discount codes

The visual editor has a simple interface for the details the agent doesn't cover.
