AI is moving incredibly fast.
AI for education. AI for coding. AI for finance.
But tonight, as I walked past a hospital, I saw so many people lying in hospital beds, struggling with illness. Many of them were elderly.
It reminded me that despite all the progress in technology, so many people are still suffering.
I hope one day AI for healthcare can advance just as quickly.
Because beyond productivity and efficiency, there are lives we could change — and lives we could save.

that's cool
$52M seed round. 15M+ users. But this is what we're most proud of yet.
Introducing Drama 3: the most emotive and controllable TTS model in the world
And yes, it's open-weight.
You can now control how even a single word should sound, change its tone, and shift your voice mid-sentence.
Uncle Roger was impressed too.

My first teammates were my college roommates.
We had no funding, no employees, and no office. Just a dorm room where we wrote code and built products together.
In my junior year, I dropped out of college to go all in—and kept building.
Today, we’re moving into a bigger office, with eight figures in seed funding and a team of dozens.
Grateful to everyone who’s helped us get here. There’s a lot more to build.
At 2 a.m., a 24-hour bookstore in Shenzhen is still packed with people studying. Shenzhen truly feels like a city that never stops learning.

Grateful to our investors for the invitation. It is a great honor to speak at YZi Labs Demo Day during The Convergence at the Computer History Museum.YZi Labs
We will be sharing our vision for the future of education: replacing the one-size-fits-all school model with a personalized AI tutor for every child. We believe every student deserves an education tailored to their pace, interests, and potential.
Excited to share the stage with Cathie Wood from ARK Invest and many visionary builders.
The best investor don’t only care about how much you’re making, they also care about how you’re doing,too.
Our investor literally shipped $1000 smart chair from china so we could work more comfortably. Big thanks to Jinqiu capital.

Let’s make it happen!
Excited to announce that @VideoTutor has raised an $11M Seed round led by @yzilabs, with support from @amino_capital and BV FUND、JinQiu Fund and others.
From day one, we’ve set out to redefine how students learn with AI transforming passive watching into interactive mastery. Our platform combines large language models with a proprietary math animation engine to deliver fully automated, step-by-step lessons and real-time feedback.
With this new funding, we’re accelerating product development, expanding our engineering team, and partnering with schools worldwide to make high-quality, personalized AI learning accessible to every student.
We’re always looking for talented people to join us and help build the future of learning together.

The education system is stuck in the past, so we're building its replacement
VideoTutor is the world's first K-12 tutor agent
The future of learning is no longer ebooks or even convos with LLMs
We’ve created a way for students to produce custom video tutorials like Khan Academy and allow them to interact with them like talking to a real tutor/teacher
Big thanks to our partners at @Trae_ai for helping us ship our product faster, and @Hailuo_AI @minimax_ai for providing us with the best ultra-realistic TTS model
YC startup requests asked for an AI personal tutor for everyone... and we delivered.
@ycombinator @harjtaggar @garrytan
Excited to share — all are welcome to join!
Trae is coming to @Stanford this Thursday, 5/8.
