nFactorial AI earns praise for engaging, well-structured learning that keeps users focused and motivated, with several calling it highly useful for quick, high-quality self-education. Reviewers highlight crisp 5-minute lectures, smooth slide-sync, and strong follow-up Q&A that feels specialized and deep. It’s seen as especially helpful for students and people with ADHD, and a fun “edutainment” format that’s easy to jump into without downloads. Critiques ask for more user control (pacing, collaboration) and broader mentor diversity. One skeptical voice questions real-world use versus general LLMs, but most feedback is enthusiastic.
nFactorial AI
Hello Product Hunt,
I'm Arman. Excited to launch nFactorial AI - video calls with world's best minds as your personal tutors.
Big vision
We set out to build the world’s biggest catalog of 100,000+ world-class masters (from Bruce Lee to Naval Ravikant) from every industry and every geography/language as your personal video-first AI tutors.
Key insight
At the moment, in many fields AI is worse than the top 1% of humans. Terence Tao is better than AI in math, Warren Buffett is better in investing, Scott Aaronson is better in computational complexity. The Lee Sedol moment did not yet happen in these fields. By embedding the thoughts of the top 1% of humans into its context, AI generates higher-quality output.
Current version
We’re launching with 6 personal heroes of mine: Paul Graham teaching startups, Elon Musk teaching physics and first-principle thinking, Andrej Karpathy teaching AI, Morgan Housel teaching personal money management, Bill Ackman teaching investing, Marc Andreessen teaching venture capital and personal productivity.
How to use the app? 1) Start a Zoom call with a legend. 2) Listen to their 5-min lecture with slides. 3) Ask them questions. 4) Ask to create a new lecture on any topic of your choice.
Product-founder fit
A lot of my friends make fun of me for being overly fascinated with learning from the GOATs. In 2004, I built the biggest Bruce Lee website on the Russian Internet. In 2010-2014 as well as 2023-2024, I recorded 150+ 3-hour long podcasts with world-class founders, scientists and engineers. In 2013, I published 966 posters on Instagram with my favorite quotes from the world’s top performers. In 2014, we built an iOS habit tracking app where users could follow daily rituals of the world’s most effective people. In 2016, 1 year before Cameo, we launched a mobile marketplace for fans to get video greetings from their favorite celebrities.
It’s time to turn this lifelong fascination into a product useful for a billion people.
What’s new about what we built?
- Live video call: screenshares by legends, see them “teach” with slides.
- Create a video lecture on any topic. Preferably within the teacher’s domain expertise for better lecture quality.
- Persona-grounded tutoring: each AI mentor is grounded in their public writing, talks, and known viewpoints, so PG sounds like PG, Karpathy reasons like Karpathy, etc.
- We mimic not just the legends’ voice, mannerisms, facial expressions and vocabulary, but also their way of thinking. Reasoning based on their public writings: 3800+ posts, essays, books, interviews and blogs.
If you try it, tell us what felt magical and what felt wrong. We're here to answer any questions

@suleimenov I want to integrate with popshort.ai, do you have any good ideas?
nFactorial AI
@alexxiang Thanks for your support! For now we’re keeping the focus on improving the core experience with our AI mentors, so we’re not planning integrations yet. But I'll keep your product in mind for the future.
@suleimenov Love how you're bringing the expertise of world-class minds into accessible AI tutoring - brilliant concept!
nFactorial AI
@kay_arkain thank you! let us know who would you like to see in our product.

Hi team, congratulations on the launch and best of luck.
It’s a really cool idea, I like these kinds of tools that help people level up through their idols.
I hope you get the well-deserved Product of the Day.
nFactorial AI
@lipkovskiy thank you Andrey! fingers crossed 🤞
we are also a big fan of such tools!
nFactorial AI
@lipkovskiy Thank you for your support & insights, Andrey! Call with you was super helpful. This would not have been possible without you.
nFactorial AI
@lipkovskiy Thanks a lot, Andrey for your support and feedback :)
Raycast
Clever approach — especially with the slide deck! Couple questions:
Did you get the permission from the legends to user their content and likeness?
What do you think of California's Right of Publicity (Civil Code § 3344) law?
I couldn't last more than 15 seconds listening to Legend Karpathy with all of the disfluencies ("ums"). I get the desire to make them sound more human, but this just makes them sound annoying. Which TTS are you using?
Do any of the world's best minds exist in female heads?
nFactorial AI
@chrismessina Hi Chris, thanks for your feedback, totally valid points!
We started working on this product only a month ago and did not yet have time to get official permissions from the legends. We are using this opportunity to invite them to officially make their wisdom (in the form of live AI-generated video lectures) available to millions of fans around the world. We are not monetising their content without their approval.
Agreed. We might have overdid with filler words. Will fix it in the next versions. We are using OpenAudio models for TTS.
Yes, they do, we couldn't incorporate them in time. We would love to add Sarah Paine to our platform. Who would you like to see?
CodeDesign.ai
It is more engaging than other options available.
nFactorial AI
@mssulthan 100%, that's our priority! we made sure the content is valuable and engaging by incorporating +3800 essays, podcasts, posts, books and blogs.
we are thinking of building a library with thousands of lectures. let us know what topics you are interested in.

To whom do you offer this? (ICP)
nFactorial AI
@busmark_w_nika Excellent question! Here are our two main ICPs:
Experts who want to scale their minds for their audiences 24/7.
Anyone who wants to learn from their heroes via real-time 1-on-1 video lectures.
smart idea ngl 😁
nFactorial AI
@ashkan_ziaee We just really wanted to help Arman talk to Bruce Lee, so we decided to build this product! Haha.
Jokes aside, I was personally excited to have Morgan Housel teach me The Psychology of Money. I hope our AI avatars help others learn in a fresh, engaging way.
PS: Bruce Lee is coming soon…

Wow, I love the idea 🔥
