Imagine having a digital clone that can speak 140 languages while your real self is limited to just three. That’s the reality Maria Garib faced when she encountered her own AI avatar created by Synthesia, a moment that perfectly encapsulates the surreal and practical advancements in synthetic media. In this conversation with Synthesia’s CEO Victor Rappavalli, the discussion moves beyond simple digital twins to explore how AI is fundamentally reshaping communication, learning, and business workflows by making video as easy to produce as a PowerPoint slide.

The core thesis is that AI is driving the marginal cost of video production—in terms of money, time, and skill—toward zero, much like how personal computers democratized writing. This isn’t just about creating marketing clips; it’s about replacing entire layers of internal business communication. Rappavalli envisions a future where static documents, training manuals, and internal memos are replaced by dynamic, personalized video. More than that, video itself is evolving from a passive broadcast medium into an interactive “agent” you can converse with, such as a training module that turns into a role-playing sales coach or a tutorial that answers your follow-up questions in real time.

For businesses today, the most immediate impact is in the “middle layer” of communication. Synthesia sees its technology not yet for Hollywood-grade ads, but for the vast quantity of internal training, product explainers, and customer onboarding that currently exists as forgettable slides or text. Companies like UBS and Heineken are already using avatar videos to communicate complex analyses and training more effectively, seeing significant gains in engagement and speed. The guiding principle is “utility over novelty,” focusing on real ROI in cost reduction, faster content creation, and better information retention rather than flashy, experimental projects.

Surprising Insights

• The Most Niche Use Case: One of the earliest adopters was a barbershop in Brazil that used the platform to create videos showcasing different haircut styles for its Facebook page, demonstrating the technology’s reach far beyond corporate use cases.
• The Critical Role of Accent: A major barrier to avatar adoption isn’t just visual uncanny valley, but vocal dissonance. People are highly sensitive to their digital clone having the wrong regional accent, which is why Synthesia built its own voice model specifically designed to preserve vocal nuances.
• A Defense of Shorter Attention Spans: Rappavalli challenges the narrative that shorter attention spans are solely due to “brain rot.” He suggests it might be a rational response to an abundance of content, where audiences naturally gravitate toward the most efficient and engaging format—like a well-made video over a dense 250-page book—forcing content to be better.
• Licensed Data as a Differentiator: Unlike many generative AI companies, Synthesia proactively licenses training data (e.g., from Shutterstock), betting that high-quality, legally-sourced input leads to superior output and provides a foundation of trust for enterprise clients.
• The Future of Hiring: Interactive AI video agents could make hiring fairer by allowing candidates to demonstrate skills through a live case study with an AI, moving beyond resume-screening biases and giving a more equitable chance to applicants from non-traditional backgrounds.

Practical Takeaways

• Start by Replacing Internal Documents: For fast wins, look at the PowerPoint decks, wiki pages, and text-based training materials in your organization. Converting these to avatar-led videos can boost asynchronous engagement and retention.
• Avoid the “Super Bowl Ad” Mistake: The rookie error is being overly ambitious and trying to create flagship advertising campaigns with current avatar tech. Focus instead on practical, high-volume communication where authenticity is valued but production budgets are low.
• Prioritize Vocal Authenticity: If creating a personal avatar, ensure you provide high-quality voice samples. The realism of the avatar hinges as much on it sounding like you—down to your specific accent—as it does on visual fidelity.
• Use AI to Expand, Not Replace, Human Interaction: Consider using personalized avatar videos for scalable, one-to-one touchpoints (like welcoming new newsletter subscribers), freeing up your actual time for deeper, real human connections where they matter most.
• Cultivate Creativity and Critical Thinking: As AI handles more execution, the most future-proof skills will be the human abilities to conceive original ideas, ask the right questions, and critically evaluate information—skills that define what’s worth building in the first place.
