YellBuddy
Vent. Scream. Laugh. Repeat.
Join the WaitlistHow Grumple Helps
Grumple is not just your AI buddy — he’s your digital punching bag (emotionally speaking, of course). He listens without interrupting, judges nothing, and absorbs your emotional chaos with sarcastic love.
Whether you're road-raging in your car or fuming after a terrible Zoom call, just let it out. Grumple will groan, nod, react, and throw back just enough sass to make you laugh again. He’s here to be your outlet — expressive, reactive, and maybe a little grumpy himself.
Oh, and yes — Grumple's face actually *changes* as you talk. Because your emotions deserve a show.
What’s Our Mission?
We’re redefining emotional support — one scream at a time. Mental health tools are often serious, silent, or require too much effort. What if the first step to feeling better was just... yelling into your phone?
YellBuddy was created with a simple belief: release is relief. When emotions pile up, people don’t always need advice. They need space. They need permission to shout, to rant, to be messy. And they need something (or someone) that can take it.
Our mission is to make that release easy, humorous, private, and surprisingly healing — powered by the most expressive AI face you’ll ever yell at.
How It Works
Open the app and start yelling, whispering, or venting into your mic. No scripts, no pressure. Just raw, beautiful chaos.
Using cutting-edge voice emotion detection, the AI reads your tone, volume, and language — figuring out exactly how fired up you are.
As you talk, Grumple responds with real-time facial expressions, sound reactions, and the occasional sarcastic snort. It’s like yelling at a cartoon mirror — only better.
As you let it out, the rage meter spikes — then slowly cools as your emotions level out. Hit maximum rage and the meter *breaks* (don't worry, Grumple’s used to it).
Why We Built YellBuddy
Because life is hard. And screaming into a pillow doesn’t always cut it.
We’ve all had those days — where your boss, your ex, the traffic, or your own brain just pushes you to the edge. You don’t want therapy. You don’t want advice. You just want to SCREAM.
So we built Grumple. A character that listens, reacts, and helps you vent — while making you laugh along the way. YellBuddy isn’t about replacing mental health care. It’s about making emotional release fun, free, and available whenever you need it.
This is our way of giving people permission to feel... loudly. Without shame. Without silence. Without a filter.
