Hey Product Hunt 👋👋
I’m Dr Cheng Feng, co-founder & CEO of Sumeru AI. 🧐We have taken a step forward in creating a REAL digital human capable of thinking and engaging in free conversation — real‑time 3D digital humans that don’t just “read a script,” they look at you, react, and serve your clients.
This real digital human can be quickly created by anyone at any time, to be Play · Help · Earn · Easy: provide solid help and be directly tied to outcomes.
🚀🚀Why we built this
Most “digital humans” are one‑way talking heads. In some scenarios, like teaching, sales, or support, you need an AI agent with mind, emotions, and professional knowledge that can present your slides face-to-face, talk to your students/clients, and understand their reactions and adapt on the spot.
This real human-like agent will not only save your time, but also can collect responses from your students/clients before you really meet. Generally speaking, we hope our Sumeru AI can better and more efficiently deliver your idea and promote your target achievement.
We utilize 3D Gaussian Splatting (3DGS) at the core for character/scene reconstruction and rendering, achieving high-fidelity, low-latency visuals on consumer-grade devices. To our knowledge, SumeruAI is the world's first team to successfully integrate 3DGS into a viable product workflow (reconstruction → control → publishing) while merging it with emotion mirroring and multilingual dialogue pipelines. This enables digital humans to maintain frame-level responsiveness within a closed-loop system of “see-think-speak.”
🌟🌟What’s new and unique in our launch
⚡ Instant setup: upload one photo and documents(coming soon) you want, choose a role, tone, language, and go — no complex pipeline.
⚡ Real‑time interaction: sub‑second responses, emotion mirroring, and on‑the‑fly re‑phrasing when users look confused.
⚡ Full customization: appearance, personality, dressing style, role, and knowledge can all be customized by simply clicking and typing.
⚡ Outcome‑oriented flows: objection handling, live quotes, lesson pacing, A/B scripts, and basic analytics so conversations can convert.
⚡ Easy to be integrated: we provide a full set of APIs that you can integrate all the functions into your own WEB/APP in 30 minutes, serve your clients with no limitations of devices.
✨✨What we’re most proud of
We turned digital humans from monologues into an instant show and interaction, all driven by AI. In our current demos, people pause, frown, or smile — and the digital human responds appropriately, clarifies, and keeps the dialogue moving. In the future, digital humans can do more things for you immediately as you call, such as dancing, playing games, and hosting live shows.
🔥🔥Equally important: we are the most economical AI digital human till now, everyone can use it on PC and mobiles of almost any model, without worrying much about the cost.

This truly solves a major pain point for engaging with complex info.
@rajpurohit_vijesh Thanks! To learn from your workflow.
Who’s the audience, what format do you use (slides/wiki), and one tough question you’d want the avatar to answer live? Drop that and I’ll reply with a 30‑sec screen record to your case.
@rajpurohit_vijesh This tool is perfect for your career. You can use your digital avatar to present your product—we'll soon support importing PowerPoint presentations or videos, and AI-powered presentations will be automatically generated. You can share this presentation with your clients, and if interested, they can ask your digital avatar questions, which will answer all their product-related questions in real time.
All of this interaction data is visible in the tool's backend. This way, you can filter your vast pool of potential customers to identify those with high purchasing intent without wasting time, understanding their true needs and preferences. You can then meet with these clients in person to quickly close deals.
Thank you for your continued support, and we welcome your continued interest in our products.
1) Q: What is Sumeru AI?
A: Your thinking 3D partner. From one photo, spin up a lifelike avatar in ~60 seconds that you can talk to in real time.
2) Q: How do I get my first result fast?
A: Pick or upload a photo → choose role/language → tap “Start Live Talk.” That’s it.
3) Q: What does “real‑time” mean here?
A: Sub‑second voice/text responses, emotion mirroring, and automatic re‑phrasing when you look or sound confused.
4) Q: Voice or text—what’s supported?
A: Both. Click the mic to speak (short messages, up to ~1 minute) or type in the box and press Enter.
5) Q: Which languages and tones are available?
A: Madarin,English,Korean and Japanese by default.
6) Q: What can I customize?
A: Appearance, dressing style, voice, persona, role, and behavior prompts—no complex pipeline required.
7) Q: Can I embed this on my site/app?
A: Yes. We provide a Web SDK and full APIs. Typical integrations take about 30 minutes.
8) Q: How is this different from a 2D “talking head” video?
A: It’s live and interactive (not one‑way), adapts to your audience in the moment, and is easy to tweak without re‑exporting.
9) Q: Is my data private?
A: You control visibility and can delete assets anytime. Sessions run over secure connections; we follow least‑data principles.
10) Q: Who is it for—and is there a trial?
A: Creators, educators, presales, onboarding, and events. A free trial is available; details and plans are on our site.
Tried it for ~10 minutes. From a single photo to a speaking 3D avatar was around a minute, and “Start Live Talk” felt instant. Loved the quick switches between friendly/pro tones and EN/中文. The mic prompts (“Tap the mic to talk”, “Stop → Send”) were clear. Tiny wish: a one‑page “what to try first” overlay after signup. Curious what presets you’re adding next!
@cecilia_xie Thanks Cecilia for your professional comment! We will update ASAP
I gave it a try, and it's pretty good—quite amazing, actually. The only odd thing is that the models' hands can't move at the moment.
@leon_chan1 Thank you for your experience. We will soon launch a version with gestures, while making avatars have richer facial expressions.
Very impressive product. I love it! I’m running an AI4Edu platform, and what Sumeru AI is building really resonates with me. Most digital humans I’ve seen are limited to scripted outputs, but what Dr. Cheng Feng and the team created feels like a leap forward: real-time, 3D digital humans that actually think, react, and engage naturally.
I can immediately see the value in education, where face-to-face interaction, emotional nuance, and adaptability matter so much. We’re especially excited about the possibility of connecting their digital human with our expert model, to make multimodal AI tutoring more expressive and truly humanlike.
Congrats to the Sumeru AI team 🚀 — excited to see how this evolves!
@william_yang7 Huge thanks! Would love to connect your expert model to our real‑time 3D avatar via SDK. — Let’s co‑pilot a tutoring use case!
I’ve tried a lot of 3D generation tools, only this one let me interact in real time. It’s awesome!o(*￣▽￣*)ブ
Plus, the character models come out with really great quality, completely satisfying what I need, also, wish it could support full-body models later on.
@talea Thank you for your suggestion, we will continue to update. We hope you can continue to follow our progress
Integrated into a small React app. Persona/look config via props was intuitive; no CORS hiccups. I like that tone/language can switch mid‑session. For roadmap: rate‑limit headers, an errors enum, and a minimal “sandbox” key for staging. Accessibility note: aria‑labels on the mic/stop buttons would be great.
@yetuo_zhu Your suggestion is great! Please continue to follow our updates~
I think this is a great tool 👍. It can quickly generate digital humans with a high level of realism. The responses are fast, and the expressions look very natural and lively, without feeling stiff. It’s also really easy to use—no complicated setup needed—and you can immediately experience interacting with a digital human. Overall, it feels just like chatting with a real person, which is both fun and very practical.
@david_pitt Thank you for your detailed comments. We will have more innovative features in the future, so stay tuned~
Used it for a creator intro. The avatar stayed on beat and rephrased nicely when I asked a vague question. Export + embed were straightforward. Two suggestions: (1) more casual voice styles, (2) a template gallery for common scenes (welcome, onboarding, FAQ). Excited to see where this goes.
@yishu_liu Thanks for the thoughtful run-through — love hearing it worked “on beat” and rephrased well, and that export + embed felt smooth.
