Kaltura vs Synthesia (2026): Competitors or complementary?

Most discussions about Kaltura and Synthesia start with the wrong assumption: that they solve the same problem. They don’t.

Synthesia helps organizations create avatar videos. Kaltura helps organizations deliver, manage, govern, measure, and increasingly interact through those videos at enterprise scale.

That’s why the two companies partner.

The real question isn’t “Kaltura vs Synthesia.” It’s which layer of the experience you’re trying to solve: content creation, enterprise delivery, or both. This guide breaks down what each does, where they overlap, and how to choose.

Kaltura vs Synthesia at a glance

Synthesia owns the creation layer; Kaltura owns the platform and interaction layer. They meet in the middle, which is exactly why they partner.

What is Synthesia?

Synthesia, founded in 2017, is one of the most established enterprise AI avatar video tools. Its strength is turning a written script into a polished, hyper-realistic presenter video in minutes, with strong lip-sync, natural delivery, and 140+ languages.

It’s widely used for corporate training, onboarding, compliance, and multilingual internal communications, and is known for enterprise-ready collaboration, review, and governance features. Pricing starts around $22/user/month and scales to enterprise. In 2026, it also added interactive video capabilities.

If your goal is to turn scripts into professional avatar videos quickly, Synthesia is one of the strongest products in the category.

What is Kaltura?

Most organizations don’t struggle to create video. They struggle to manage everything that happens after the video is published: distribution, governance, engagement, analytics, personalization, and interaction.

Kaltura (Nasdaq: KLTR) is the Agentic Digital Experience company. It’s an enterprise platform that spans video management, webinars, virtual events, video portals, and learning, with deep analytics and enterprise governance underneath.

On top of that platform, Kaltura added real-time Agentic Avatars: two-way conversational AI video agents that understand intent, are grounded in your organization’s knowledge, can see a user’s screen and camera, and respond live. It also offers an Avatar Video Production Studio for turning enterprise knowledge into avatar-led videos.

Where Synthesia focuses on creating the avatar video, Kaltura focuses on the surrounding experience: distributing it at scale, managing it, measuring engagement, and extending it into interactive, agentic conversations. Pricing is custom and enterprise, sales-led.

The key point: They partner

Kaltura and Synthesia announced a partnership in 2025, and it remains active in 2026.

The partnership exists because the two platforms solve different parts of the same workflow. Synthesia helps teams create avatar content. Kaltura helps them operationalize that content across learning, communications, events, customer engagement, and video experiences.

Through this partnership, organizations using Kaltura’s video platform can distribute Synthesia’s avatar-based, AI-generated video content at scale. In practice, that means Synthesia handles hyper-realistic avatar video creation, and Kaltura handles management, distribution, engagement analytics, and interactive delivery.

Early use spans healthcare, pharmaceuticals, technology, telecoms, and higher education, for enterprise training, onboarding, multilingual e-learning, and personalized marketing. The two products are designed to work together, not to replace each other.

Where they overlap

The overlap is avatar video. The difference is everything around it. Kaltura has its own avatar video production and real-time agentic avatars, and Synthesia added interactive video in 2026. So both touch “avatars” and both serve enterprise training and communications.

The distinction that still holds: Synthesia is creation-first (script to polished video), while Kaltura is platform-first (manage, distribute, govern, and make interactive across your entire video estate).

How Kaltura helps

If your goal is simply to produce avatar videos, Synthesia does that exceptionally well, and Kaltura partners with it for exactly that reason. Where Kaltura adds its own value is in everything that happens around and after creation.

Kaltura’s platform manages and distributes video at scale, measures engagement, and adds real-time, agentic avatars that turn one-way content into two-way conversations grounded in your organization’s knowledge, all with enterprise security, compliance, and analytics. For organizations that want avatar video creation and a full enterprise experience platform, Kaltura is the layer that ties it together, and it works with Synthesia to do it.

Most avatar videos are still monologues. They deliver information, but they can’t respond when a viewer has a question. Kaltura’s Agentic avatars change that dynamic. Instead of ending the interaction when the video finishes, they keep the conversation going, answering questions, providing guidance, and adapting to user intent in real time.
