The demand for video content has never been higher, and AI is completely changing the game for content creators.

AI algorithms can now streamline workflows, enhance creativity and improve video content's overall quality and viral potential.

When it comes to video production, AI video generator APIs can automate time-consuming processes like scripting, editing, rendering and captioning, allowing creators to make videos faster than ever before while still maintaining quality.

This is all down to the power of agentic workflows. An AI agentic workflow is a series of tasks managed by multiple autonomous AI agents who can independently make decisions, adapt to changing circumstances and meet goals without constant human oversight.

Thanks to AI, video creators now have a virtual assistant that understands their goals, brand and messaging and can work around the clock to create, repurpose and schedule content.

The global AI video generator market size was valued at USD 534.4 million in 2024 and is projected to grow to USD 2,562.9 million by 2032, driven by a growing demand for scalable content solutions.

If you’re a content creator or marketer who is skeptical about AI, now is the time to drop any preconceived notions and explore how agentic workflows could save you hours of work every day.

In this article, we’ll explore the growth of AI-driven video content in 2025 and highlight the importance of AI video generator APIs for creators, entrepreneurs and marketers who want to save time and money by automating their content workflows.

We’ll also compare Argil to two other AI video generators on the market – Synthesia and HeyGen.

What Are AI Video Generator APIs?

AI video generator APIs are artificial intelligence tools that integrate with existing systems to automate and optimize video production tasks.

API stands for Application Programming Interface and refers to a set of rules that allow software applications to communicate with each other. They are used in many everyday apps and programs, from Uber to Netflix.

The Benefits of Using an AI Video Generator API

Making the shift from manual to AI-driven agentic workflows can cut or drastically reduce the time you spend on laborious tasks like script generation, video editing and audio translation.

In a nutshell, automating your workflows can reduce video production time by up to 70%, allowing you more time to focus on creativity and strategy.

But automation isn’t just about working faster. AI agents can also help you improve the quality and relevance of your video content in the following ways:

• Improved personalization for different audience segments
• Instant multilingual captioning and translation, helping you connect with global audiences
• Enhanced viral potential by examining current trends and highlighting engaging “hooks” in your content
• In-built optimization features to improve discoverability across platforms

How to Choose the Right AI Video Generator API

As we've already mentioned, Argil isn’t the only AI video generator API on the market – far from it. So, how do you know what to look for when it comes to automating your content workflows? Here are some key criteria for choosing an AI video generator API.

Ease of Integration

Whatever kind of content you create, chances are you rely on a suite of tools to create and share your work with the world.

Whether it’s HubSpot for email marketing or Canva for creating social media graphics, APIs should seamlessly integrate with existing tools and platforms to create easy, automated workflows.

Customization

APIs should also be customizable so you can tailor your video outputs to match your brand’s voice and style and maintain consistency across your platforms.

To tell if an API is customizable, look for features such as adjustable parameters, optional fields in data structures and configuration options within API settings.

Scalability

You want your AI video generator API to grow with you, so it’s important to choose a scalable interface. An API is considered scaleable if it can handle a large number of requests without significant performance problems.

When it comes to marketing and content creation, look for APIs that can handle high-volume content production without compromising quality, like Argil.

Affordability

Affordability is a key factor to consider when choosing an AI video generator API, especially if you’re just starting out as a content creator or entrepreneur.

Like you would with any other productivity or optimization tool, it’s important to evaluate different pricing models to make sure they align with your budget and growing usage needs.

User Experience

You shouldn’t need technical experience to use an AI video generator API. Look for applications with intuitive interfaces where there is no learning curve – like Argil, which employs a drag-and-drop interface for ease of use.

2025 Comparison: Argil vs Other AI Video Generator APIs

Other AI video generator APIs include popular tools like Synthesia and HeyGen. However, there are some crucial differences that set Argil apart from other competing platforms.

Avatar Presentation

While Argil’s AI clones appear hyper-realistic and natural, Synthesia’s avatars can appear robotic, making them ill-suited to content creation. HeyGen’s avatars also lack realism.

Multilingual Support

Argil’s API offers seamless translation, voice cloning and captioning in multiple languages. Synthesia supports over 120 different languages, but the quality of voice cloning varies and can – again – sound robotic and unnatural. HeyGen reportedly lacks smooth translation automation.

Ease of Use

Argil’s user-friendly API boasts seamless integration and easy access for non-technical users, while Synthesia requires a more complex setup and may not be accessible for beginners. HeyGen’s interface is intuitive, but some features require manual adjustments, which can be complex and time-consuming.

Cost

Argil offers flexible pricing with API access starting at $39 per month, with 30% off for yearly commits. We also offer pay-as-you-go options for larger businesses.

Synthesia advertises higher costs, starting at $49 per month for API access and 360 video minutes. HeyGen is by far the most expensive, starting at $99 per month for API access and 100 video credits.
