Introducing NeuroChat: the world’s first neuroadaptive chatbot that adapts its responses to your cognitive engagement. By reading brain signals in real time, NeuroChat personalizes its teaching style to your attention, curiosity, and focus. NeuroChat works with your brain, not around it. Developed at the MIT Media Lab.

you will not steal my thoughts, demon

🧠 Here’s how it works: NeuroChat measures real-time brain activity using EEG - a lightweight, noninvasive sensor that captures your level of engagement while you learn. The chatbot uses this engagement score to adjust how it teaches - simplifying, deepening, or changing pace to match your focus. A live feedback loop between your mind and the model.

NeuroChat isn’t mind-reading. It tracks only engagement signals, not specific thoughts, memories, or emotions. 🧩 All processing happens in your browser, and it’s compatible with local AI models, keeping brain data private.

Traditional neuroadaptive systems rely on fixed, pre-programmed difficulty levels. NeuroChat is the first to use generative AI to adapt on the fly. Every response — tone, depth, pacing — is co-authored by your brain and the model.

Built @FluidInterfaces in the @mit @medialab, we ran a pilot study (n = 24) comparing NeuroChat to a non-adaptive chatbot. -⚡ EEG engagement: significantly higher with NeuroChat - 💬 Self-reports: users described it as more human-like, fluid, and enjoyable - 📘 Learning: similar short-term scores, but stronger sustained focus and curiosity

Why now? Another study from our group by @nataliyakosmyna recently showed that using LLMs for complex tasks reduces neural connectivity and cognitive engagement. Now we’re using the same science to counter that effect.

This is an early glimpse of neuroadaptive AI - systems that collaborate with the brain, not compete with it. Imagine AI that adjusts to your focus while coding, or amplifies imagination while creating. The next generation of AI interfaces will be co-regulated by the human mind.

Huge thanks to the team behind this work: my co-authors @nataliyakosmyna, @oscar_petrov, Rebecah Kaplun, and my PI @PattieMaes - and everyone at @AHA_MediaLab @FluidInterfaces @mit_jwel who made NeuroChat possible. Special thanks to Nikos Bellos, @sundayajak & @mianirtizaaftab for dev and video support.

@oscar_petrov @PattieMaes @AHA_MediaLab @FluidInterfaces @mit_jwel @sundayajak @mianirtizaaftab And shoutout to @Isabelle_D10 for being our video model!

This is incredible. A neuroadaptive intelligence layer was very much a need. Wondering how much input would be required from the user. Also building an EEG band to stimulate flow state on command + drive cognitive insights (so like whoop for your brain), would so love to chat! :)

This is great. Are you open to podcasts interviews?

Sure! You’re the second to ask today!

DM’d!

About time my neurons got a seat at the conversation. 🙃

@prb5h check this out

incredible but will this have like a long term effects on the brain after some certain period of time ? especially to the brain that still in the development stage

There are no side effects from wearing the EEG as it just detects electrical activity. The device, @InteraXon Muse, is even used for sleep and meditation tracking! Our next steps indeed include a study to look at the long term effects of NeuroChat. We’re not testing it on minors, as that has its whole own set of ethical and consensual challenges.

@InteraXon nice wonder if like neurosurgeon or any researchers on this sector needs to be asked about their opinions is it needed FDA approval or no

This is in the research state so far 😉 My co-author and mentor @nataliyakosmyna is one of the world’s experts on designing non-invasive brain-computer interfaces for consumer applications. The Muse is not FDA approved as it’s used for consumer wellness applications, but medical-grade EEG devices exist (and have been around for a long time!)

This is absolutely wonderful. Been thinking about this. Can’t wait to deep dive.

Mindbending stuff! Needs to be integrated with another consumer app/product, to actually be used in schools/unis. What do you think of the BCI approach from @neuralink

@JimDMiller Highly persuasive AI might be happening quicker than I imagined.

I love everything that brings us closer to the singularity

A monumental waste of time, talent, and treasure was devoted to something that would inevitably degrade human interaction and relationships. Way to go nerds.

Thank you to yourself and your teams for your work. This is an exciting innovation with so many possible, positive flow on effects for the world.

NeuroChat represents a breakthrough in adaptive learning interfaces. Real-time brain signal integration enables truly personalized education by matching teaching style to cognitive state. This moves beyond static content delivery.

The mark of the beast

this is exciting, would love to try it out! build a simple mvp with a muse a while ago always excited about BCI applications :)

Congrats! This is very exciting project! I'm working on something similar for relaxation sessions. Do you use Labram for EEG classification?

🔥

@jonxuxu

That’s mind-blowing 🤯 Literally merging AI with how our brains work.

Is engagement the only metrics that you are going for? I don't know how the brain signal works, is it difficult to perform interfering write operations in the brain signals?

We have other metrics like prefrontal alpha asymmetry (measuring approach/withdrawal) integrated in the system but not tested. We’re particularly interested in confusion tracking, and just built a custom model combining EEG & eye tracking - more here:

I understand. I'll read more about it. This seems interesting.

LOVE THIS SM

What a product!

Really cool research! Can I buy this neural band somewhere?

Yes - we used the consumer-friendly Muse EEG headband: (no promotion). It's typically used for sleep and meditation tracking!

Tysm! Is it possible to move a mouse cursor reliably using commercially available non invasive trackers? I saw neuralink’s UX video today and it looks very compelling.

@dunyaverse NeuroChat powered by a Generative UI would literally be a disruptive technology. UI that adapts to your brain states using colors, font sizes, etc. to improve learning. Been thinking about making something like this for a while, NeuroChat sets a good foundation!

Nicee

Sick!

lets goooooo

Amazing Dunya!

Congrats

Congrats, Dunya. Looks interesting, good luck!

Thanks, Muratcan!

You AI psychopaths belong in an insane asylum. Fucking kabbalah psychopaths

This is where it gets scary. The power of NeuroChat is insane for learning. But if the AI is reading my brain signals to personalize, where do those neural data logs go? The governance and privacy problems just became 10x harder.

I can’t speak about the future, but in NeuroChat, all data processing and storage is done locally in the browser - the raw brain data never leaves your computer. The only thing we send out to a server is a singular aggregated engagement score with each chatbot query.

That local processing is great to hear! Huge win for privacy. But the challenge shifts to the aggregated score. What can be inferred about my mood, health, or focus over time just from that singular score? Inference risk is the next governance problem.
