The School of AI is an educational platform founded by Vivian Aranha, a technologist with over 20 years of experience in web, mobile, and emerging technologies. Launched earlier this year, the School of AI was created to help students navigate a challenging job market by building practical skills in artificial intelligence, including generative AI, agent-based systems, and fast-evolving tools.
What began as small, live internship-style sessions quickly revealed a larger opportunity: reaching more learners, more efficiently, through video-based education. However, creating high-quality video content at the speed at which AI evolves turned out to be a major challenge, until Vivian discovered HeyGen.
Scaling education without increasing workload
Right from the beginning, video was central to how Vivian teaches. “I’m not someone who learns from books,” he explained. “I need to see things in action, like hands-on labs and videos that show how things work.”
Initially, the School of AI depended on live online sessions. Very soon, students asked Vivian to record the lessons so they could learn according to their own schedule. While this made sense from a teaching perspective, it created a major production burden.
Before HeyGen, creating courses was slow, exhausting, and rigid. Vivian described building a flagship AI course in 2024 that totalled around 60 hours of content.
“I recorded the entire course myself,” Vivian said. “It took me three months, working nearly 40 hours a week.”
Even worse, AI tools evolve very quickly. Vivian often realised that content recorded on one day became outdated the very next day because of new model releases or feature updates.
“There were times when I would prepare everything at night, start recording the next day, and realise something had already changed,” Vivian said. “I’d have to redo everything.”
At that pace, Vivian could only produce around four courses a year, and he did not even realise how limiting that was until he saw another option.
Discovering HeyGen and rethinking what was possible
Vivian first came across HeyGen while looking for translators to take his courses to an international audience. He wanted to translate a course on AI and quantum computing into Spanish and brought in a human translator to support the work.
After about two weeks, the translation was still not finished. Around the same time, Vivian tried HeyGen’s trial. He uploaded his course, and within 15 minutes, the translation was completed.
“Within a couple of hours, I had translated and uploaded the course and made it available for my Spanish audience,” Vivian said.
That moment changed everything. Vivian went on to translate 20–30 courses using HeyGen and started exploring other features. Soon, HeyGen became central not just for translation, but for content creation itself.
By using scripts and screen recordings, Vivian could focus on teaching while letting HeyGen manage the delivery. He rebuilt the same 60-hour AI course in 2025 using HeyGen, and the difference was remarkable.
“It took me a fortnight instead of three months,” Vivian said. “Not 40 hours a week for months. Altogether, it was just about two weeks.”
What used to be four courses in a year became four courses in a month. “That means I suddenly had 11 extra months to focus on other work,” Vivian said.
He even created a complete two-hour course while flying to Turkey, working quietly on the plane using in-flight Wi-Fi.
Vivian’s turning point came when he created his digital twin.
“The magical moment for me was when I gave it a script and saw the expressions come alive,” he said. “When it’s excited, it actually looks excited, just like me.”
Rather than feeling artificial, the avatar felt personal and expressive. “It doesn’t look like just another avatar,” Vivian said. “It looks like my digital twin.”
That emotional realism helped Vivian trust HeyGen as the main way to create and deliver his teaching at scale.
Transforming time saved into business growth
By Vivian’s estimate, HeyGen saves him 80–90% of the time that was earlier required to produce video content. Instead of four courses in a year, he can now create four courses every month, effectively a 10x increase in output.
That increase in production has a direct impact on revenue. “It’s not only about saving time,” Vivian said. “It’s actually multiplying my revenue.”
HeyGen also enabled extensive global reach. School of AI now serves learners in more than 70 countries, with students speaking over 60 different languages.
Subscriber growth has picked up pace as well. Earlier, Vivian used to see steady month-on-month growth, but in the last eight months he has gained millions of views and subscribers, powered by consistent, multilingual content.
Beyond the numbers, HeyGen has taken the friction out of the creative process. “I’ve completely forgotten how difficult video creation used to feel,” Vivian said. “Now I simply concentrate on what I want to teach.”
His advice to others is straightforward: focus on what you are good at.
“Video making is a skill in its own right,” Vivian said. “Let HeyGen handle that so you can focus on learning, teaching, and delivering value.”
As the School of AI continues to grow, HeyGen remains the foundation that enables Vivian to teach more quickly, reach a wider audience, and keep pace with the technologies he is helping others to master.
“HeyGen helps you create professional-grade videos with just your script,” he said. “You do not need anything else.”
