Personalize with variables

Personalize videos at scale with Gan.AI variables. Customize names, companies, subtitles, thumbnails, voice lines, and landing pages using dynamic text and Voice AI.

What are variables?

Variables are essential components for adding personalization to your video projects. They serve as placeholders for the dynamic information you want to customize—such as names, company details, or other unique data points.

Instead of creating separate video versions for each prospect, you can define specific elements as variables. These variables are automatically replaced with the personalized values you provide during the rendering process.

By setting up variables, you can efficiently produce multiple versions of the same video—each tailored to individual viewers—without recording or editing new footage every time. Depending on your project setup, these variable values can be updated either manually or through automated data integration.

Different Types of Variables

• Voice AI Variables — These allow you to change spoken content (voice clone & lip-sync) in the video itself.

• Text Variables — These are placeholders for text elements across the project: script lines, landing page headings, thumbnails, subtitles.

Different types of personalization

1. Voice AI & lipsync:

• You can customize the spoken content in your videos by adding Voice AI variables. These variables allow you to modify specific parts of your script using your cloned voice, giving each video a unique and personal touch. To create a voice variable, simply click or select one or more words in your script. The selected words will be marked as variables that can be dynamically replaced during video generation. Please note that videos containing voice personalization may take up to one week to process, as they require additional voice synthesis and review time.

1. Video landing pages:

• Each personalized video copy is hosted on a unique landing page. Use text variables in landing pages to personalize titles, headings, call-to-actions, social links, and even redirection URLs. You can create highly engaging experiences for each viewer by addressing them by their name and including relevant details throughout the page.

1. Personalized Thumbnails:

• Thumbnails provide a quick snapshot of your video and play a key role in capturing viewer attention. You can personalize them to boost engagement by adding text variables—allowing you to dynamically include details such as the viewer’s name or other customized information. Additionally, you can choose between static or animated thumbnails, or upload your own custom thumbnail to best represent your video.

1. Personalized subtitles:

   You can personalize subtitles in your video by using text variables. This allows each version of the video to display unique details—such as the viewer’s name, company, or location—directly within the subtitle text. Personalized subtitles make your content feel more relevant and engaging for each viewer. For example, instead of a generic greeting, the subtitle could read: “Welcome, John from TechCorp!”

1. Automatic Background:

• The Automatic Backgrounds feature enables you to add dynamic, personalized background content behind your video for each recipient. Rather than a static background for all viewers, you can display custom content such as a viewer’s website, LinkedIn profile, a branded image, or a tailored video clip—creating an immersive, personalized experience at scale. As of now, we only support LinkedIn profiles and Facebook profiles as automatic background only.

By combining Voice AI variables, text-based customization, personalized thumbnails, subtitles, and dynamic backgrounds, Gan.AI gives you complete control over how each viewer experiences your video. Variables turn a single recording into a deeply personalized message—one that feels intentionally crafted for every individual. With these tools, you can deliver highly relevant, immersive, and human-centric interactions at scale, all while saving significant time and effort in production. The result is smarter communication, stronger engagement, and a truly custom experience for every recipient.
