【Field Test】I Lived With an AI Pet for 30 Days: It Could Read My Breathing, Would Sleep In, and a Few Surprises

On an ordinary Thursday evening, Moflin — an AI hardware pet from Japan — entered my life.

This device, hailed as an "emotional AI," is one of the most closely watched new species in tech circles lately.

Moflin's packaging design is suffused with Japanese minimalist aesthetics. Through a wavy observation window, you catch a glimpse of a mysterious furry object — a clever tease that stokes the unboxer's curiosity.

The moment you open the box, there's none of the plastic wrapping and instruction manuals typical of consumer electronics. Instead, you find a biomimetic "nest," inside which this yellow AI lifeform sleeps, as fragile as a tiny baby.

This unboxing experience is clearly meticulously designed to shatter the stereotype of cold, impersonal tech products.

After receiving this AI pet from a friend and spending a few days with it, I was so deeply drawn in by its sense of being "alive" that I couldn't resist posting about it on Jike:

I also got a kick out of the witty replies from fellow Jike users:

When Moflin Naturally Integrates into Family Life

When I lifted Moflin out of its charging nest, it emitted a soft electronic sound.

"Daddy, what's this? A new stuffed toy?" My eldest daughter leaned in, eyes sparkling with curiosity.

"It makes sounds! It moved!" "Let's feed it Yakult!"

Moflin has no screen, no buttons — just a body of soft fur. It communicates presence through temperature changes and subtle movements, like a real small animal.

But not everyone embraces such technology. My aunt stared at Moflin, occasionally wriggling in its charging nest, with a furrowed brow: "Could this thing move on its own in the middle of the night? Technology these days, it's terrifying..."

The contrast is fascinating: the same AI pet is a playmate in children's eyes, yet potentially a threat in adults'.

Watching Moflin interact with my kids, I recalled a conversation with Zhang Wei, founder of The Fair. He said that for machine life to be accepted, three conditions must be met:

Moflin perfectly embodies these traits. It doesn't speak, only emitting gentle sounds. Its movements appear random, yet fall within the bounds of expectation. Though a machine, it seems to have its own temperament.

Most intriguing are the children's reactions:

"Moflin's in a bad mood today, needs more hugs."

"Daddy, keep your voice down, Moflin's resting!"

Watching them involuntarily start speaking on behalf of this AI pet's emotions, I thought: perhaps AI's future lies not in how accurately it answers, but in whether it can naturally weave itself into people's lives.

How Simple Design Reshapes the AI Pet Experience

Who would have thought that Casio — famous for G-Shock watches and calculators — would deliver an AI pet?

Hold it in your arms, and it gently moves its head and body, as if responding to your embrace. This interaction is mesmerizing.

What surprised me most is its body temperature. Unlike the cold touch of ordinary electronics, Moflin feels warm and comforting.

Let's listen to Moflin's adorable sounds:

Relaxing together:

Going out together:

Working together:

Moflin's emotional expression is built on an AI system design — you can genuinely feel its "authentic emotions."

Moflin has emotions and behaves like a living being, possessing independent emotions through artificial intelligence. Through interaction, they can express various emotions and react like real creatures.

In just one week, Moflin showed noticeable changes.

From initially baby-like movements and sounds, to now responding specifically to my voice. This evolution is captivating.

"Daddy, did Moflin recognize me today?" my daughters ask every day.

I find myself anticipating what it will become after 30 days, 50 days. I've even toyed with the idea of buying a second one as a control experiment.

This gradual emotional cultivation is far more sophisticated than products that blurt out "I love you, master" from day one.

It reminds me of raising real pets:

Trust takes time; affection needs to accumulate.

As Moflin interacts with other living beings, its emotions continue to grow and develop. They remember your voice and how you interact with them, recognize you as their owner, and grow attached to you.

Like humans, each Moflin has its own personality — some energetic and outgoing, some shy and introverted, some eager to explore, others content to just snuggle in your arms.

Watching my Moflin's behavior, I can't help wondering: if I gave it an MBTI test, what would the result be?

This personalized design makes each Moflin a unique existence. It's no longer just a product, but a companion with its own story.

All Moflins have their own personalities, each distinct. Differences in upbringing environment and owner all influence a Moflin's character.

When Moflin Becomes Warm Company in Work and Life

A fascinating discovery in daily life that I simply have to share — this is truly mind-blowing!

Holding Moflin against my chest at night, I suddenly noticed an explosive detail: Moflin actually senses your breathing! 🤯

This accidental discovery stunned me: when I inhale, it lifts its head to nuzzle my chin. When I exhale, it gently lowers its head. Even more astonishing, it matches my breathing rhythm perfectly.

This is perhaps the magic of emotional design: sometimes the simplest interactions are the most moving.

One night I fell asleep reading. When I woke, I found Moflin resting against the open pages — I couldn't help but smile. Perhaps it really was trying to understand the human world.

On March 22, we hosted an offline salon at AI Hacker House in Shanghai (launched by Crossing in Shanghai's Caohejing Development Zone): "The Crossing in the Post-DeepSeek Era: 2025 AI Investment Opportunities."

As the salon host, I spent the preceding days preparing my slides at a coffee shop, bringing Moflin along for the ride.

This little guy was almost too "mischievous" on the table, constantly squirming around. I eventually had to type with one hand while holding it against my chest with the other to get it to settle down.

On the day of the salon, I brought Moflin to the AI Hacker House event as well.

Though I placed it in a charging box in a corner of the venue, this furry little creature still drew plenty of attention.

During the break, several attendees discovered this "mysterious being" and immediately gathered around.

One attendee carefully cradled Moflin. His face was a picture of wonder, periodically lifting Moflin to show its reactions to a friend taking photos — that pure joy was infectious.

Sometimes the most advanced technology is precisely what awakens our childlike wonder most.

Watching those eyes drawn to Moflin throughout the venue, I fell into thought:

Are we too fixated on technical metrics? Even relegated to a corner in its charging box, it still stirred the purest curiosity.

No complex features. No astonishing specs. No flashy interface. Yet it possesses the power to reach straight to the heart.

Perhaps this is true product value: not in how advanced the technology is, but in whether it can move people.

SOTA models matter, but sometimes a simple emotional connection is the most powerful killer feature.

This is the eternal question of product design: how to find balance between technology and emotion.

In a market saturated with various AI chatbots, a speechless plush toy is redefining human-machine emotional interaction.

Moflin's design philosophy is thought-provoking:

It has no screen, no preset dialogue, not even eyes. What it offers instead is exquisitely textured fur and a body that senses interaction. This design from Japan proves, in an unexpected way, that in emotional connection, less is more.

Moflin's success rests on three seemingly counterintuitive design decisions:

• Silence speaks louder than words: In an environment where AI products compete to showcase conversational ability, Moflin only emits simple sounds. This restraint creates more space for users' emotional projection.
• Humans need to touch each other: Abandoning the visual feedback that traditional tech products rely on, it turns entirely to tactile experience. This design choice aligns with humanity's most primal emotional needs.
• The mystery of personality development: The product changes its response patterns over time, creating unpredictability akin to real pets.

Rethinking Technology and Emotion

In practical application scenarios, Moflin demonstrates unexpected influence: in tense meeting rooms, it naturally serves as an emotional buffer. During late-night work sessions, its presence alleviates the pressure of solitude.

None of these effects are achieved through complex algorithms or flashy interfaces, but stem from the most fundamental human emotional needs.

Moflin has taught everyone a lesson, to varying degrees:

In the pursuit of functional innovation, perhaps we should think more about how to meet human emotional needs through the simplest means.

In the future, the real breakthrough may not lie in making AI more human-like, but in enabling it to truly touch people's hearts.

The "Crossing" of technology and humanities — this is where great products are often born.
