I created an interactive digital avatar of myself — and you can talk to it
Source: TechCrunch ↗
Synthesia, the video‑generation startup valued at $4 billion, created an interactive digital avatar of journalist Alex Karp, training it solely on his story about venture‑backed startup fraud. The avatar, built using Synthesia’s own video and voice models alongside third‑party speech‑to‑text, language, and text‑to‑speech engines, can answer only questions related to that specific article, redirecting any other queries back to the story. Karp’s experience began when Synthesia’s head of corporate affairs, Alexandru Voica, sent him a link to his own AI avatar, prompting Karp to request a personal twin during a visit to the company’s new New York office. Within a few days the team produced both a “personal” avatar that could recite a generic script and an “interactive” version that engages in deterministic dialogue about the venture fraud piece.
The demonstration highlighted Synthesia’s three‑pronged product strategy: a classic video‑creation platform where users script avatar speech, an agentic “Sessions” platform enabling interactive role‑play and surveys, and an API that lets enterprises combine Synthesia’s video and voice models with external cloud services. The interactive avatar leverages a pipeline that converts spoken input to text, processes it with a language model to determine a response, synthesizes audio, and animates the avatar in real time. Karp noted the voice sounded close to his own, though not identical, and that the visual likeness was “somewhat creepy” to friends, while his parents were impressed despite the avatar’s refusal to answer personal questions. The deterministic nature of the model—restricting answers to the trained content—illustrates both the technical possibilities and the current limits of AI‑driven digital twins.
Karp’s experiment raises broader questions about the future role of AI avatars in journalism and corporate communication. While some investors immediately dismissed the idea of news delivered by synthetic presenters, others see potential for avatars to augment or even replace human journalists, especially in repetitive briefing or training contexts. The technology also prompts ethical considerations about authenticity, consent, and the uncanny valley effect, as illustrated by Karp’s family’s mixed reactions. As Synthesia expands its offerings and invites more clients to create personalized avatars, the industry will need to grapple with how such tools reshape storytelling, audience trust, and the balance between human nuance and AI efficiency.
