You’ve probably seen him on Instagram. A bald monk with a calm voice drops life advice on your feed. Millions of views. Thousands of comments from people who feel genuinely moved.
Yang Mun isn’t a real person. He’s an AI character built entirely with HeyGen by creator Shalev Hani. And accounts like his are exploding across Instagram, TikTok, and YouTube right now.
Shalev grew Yang Mun to over 2.5 million Instagram followers with a simple formula: one clear concept, about 20 minutes of production time, and HeyGen. No camera. No studio. No traditional talent or production team.
Who watches
Yang Mun speaks to adults ages 25-50 who scroll Instagram looking for something most feeds can’t provide. Shalev Hani, the creator behind Yang Mun, describes his audience as “adults who seek calm, emotional clarity, and spiritual grounding.” They don’t want noise. They want a moment of stillness. And they're not alone. We're living through a wellness shift where slowing down and prioritizing mental health have moved from niche interests to mainstream priorities.
Video carries the entire strategy. “Video is the core medium for delivering presence, tone, and trust,” Shalev explains. “A text post can share wisdom. A video makes you feel it.” That’s why he builds everything around video and nothing else.
The problem
Before HeyGen, every video required a lot of manual effort to script, record, edit, and publish. Shalev describes his earlier process as “slower and more resource-intensive, which made it hard to stay consistent.” He could manage a few videos per week, which sounds reasonable until you understand how Instagram actually works. The algorithm rewards daily consistency. Posting only a few times a week means less reach, slower growth, and a ceiling that Shalev could sense but just could not break through.
The deeper challenge was sustainability. “Maintaining regular posting without burnout” was the specific pain point. The meditative quality of the content demanded precision in tone and pacing. Keeping that standard while publishing frequently enough to grow was a grind that couldn’t last.
“Use technology to serve the message, not distract from it.”— Shalev Hani, creator of Yang Mun
Why HeyGen
Shalev started searching for an AI video solution when he realized he needed to “scale content while preserving authenticity.” He wasn’t looking for a shortcut. He needed a tool that could handle the production load without introducing the uncanny valley into the final product.
He evaluated several platforms and chose HeyGen for one key reason. In his words, “It felt the most human and non-intrusive, keeping the focus on the message.” Other tools introduced visual or tonal elements that drew attention to the technology. HeyGen did the opposite. It blended seamlessly into the content.
Onboarding was quick. Shalev and his team became comfortable with the suite of tools “in less than a few days.” There was no steep learning curve and no need for lengthy experimentation. They went from first use to production-quality output almost immediately.
How it works
For the Yang Mun account, ideas come from two places: recurring audience struggles and timeless spiritual themes. Shalev says he doesn’t chase trends. He finds where what people need right now overlaps with what has been true for centuries. That combination gives each video both immediacy and depth.
He writes short, simple scripts. That is the single most important lesson Shalev learnt early. When asked what he wishes he had known from the start, his answer was direct: “Simple scripts perform best.” The temptation with AI video tools is to write longer and more complex content because the technology can handle it. But the audience does not want complexity. They want one idea, delivered clearly. When he does not have a script ready, he uses HeyGen's script writer to create one.
The other features he depends on the most are “avatar delivery and voice.” No fancy graphics. No complicated, multi-layered edits. The format stays minimal and message-first because, as Shalev says, “minimal, message-first videos are what connect with people.” Since it’s so easy to create videos on HeyGen, he produces content in batches, writing scripts and creating multiple videos in a single sitting, then scheduling them across the week.
Do audiences care that he’s AI?
This was Shalev’s biggest concern before the launch. He admits that “authenticity was the concern” from the very beginning. If the audience felt deceived, the entire project would fall apart.
What happened was the opposite. “Audience response resolved it,” Shalev says. People focus on the message, not the technology. Comments and engagement patterns indicate that viewers connect on an emotional and spiritual level. No one assesses whether the monk is real. They absorb the teaching, reflect on it, and share it.
When asked about the most surprising benefit of using HeyGen, Shalev didn’t point to speed or cost savings. He pointed to connection: “how naturally audiences connect with the content.” When the message is genuine and the delivery is consistent, the technology becomes invisible.
The results
“We moved from a few videos a week to daily content,” Shalev confirms. That single change transformed the entire trajectory of Yang Mun.
Posting frequency, reach, and engagement all climbed. But the deeper result is what daily publishing actually means for a mindfulness brand. Spiritual guidance isn’t something people seek once a week. They return to it every morning, every evening, every time they need a mental break and calmness. Daily publishing made Yang Mun available to his audience in the way they actually needed him.
Overall, HeyGen videos performed as well as, or even better than, traditionally produced content. Shalev credits this largely to consistency: “Equal or stronger because of consistency.” The algorithm rewards daily publishing. The audience values reliability. HeyGen made both possible without any compromise on quality.
“How naturally audiences connect with the content has been the most unexpected advantage.”— Shalev Hani, creator of Yang Mun
The playbook
Yang Mun is not an anomaly. He is a blueprint. The same system that built this account works for any creator or brand seeking a consistent, recognisable AI-powered video presence.
The principles carry over directly. Start with a clearly defined audience and a clear message. Use HeyGen’s avatar and voice tools to create a character people recognise and trust. Write simple scripts. Batch your production. Publish every day. Let the technology handle the production workload so you can focus on the creative decisions that truly matter: what to say, how to say it, and why your audience needs to hear it.
Shalev now teaches this exact system.“The same system used to build and scale Yang Mun is now taught in a dedicated course for creators and brands who are building AI-powered characters.” It covers everything from character creation and scripting to production workflows and publishing strategy.
What’s coming next
Shalev plans to guide Yang Mun “towards deeper teachings and a wider reach.” The HeyGen feature he is most excited about is “even greater emotional nuance in delivery with Yang Mun in different environments and settings”. It is the ability to convey subtle shifts in tone that makes the content feel even more present and alive.
But the core philosophy remains the same. Technology serves the message. The message serves the audience. Everything else is just noise.
