The Solution
Introducing Sein Clip.
A wearable AI companion that learns how you think.
How It Works
Observe → Process → Incinerate → Distill → Reflect → Ask&Answer
Real-Life Scenarios
Self-Tracking: Recognize Your Patterns, Reclaim Your Energy
Q: “Why have I been feeling so drained lately?”
Sein’s Answer: “You’ve mentioned feeling ‘tired’ frequently over the past two weeks, often with a faster speech rate and higher volume. Your data shows a consistent energy dip after 4 PM. We suggest scheduling a short break around that time to recharge.”
Relationships: Communicate with Empathy
Q: “Was I too harsh when I spoke to my partner yesterday?”
Sein’s Answer: “In similar situations, you usually express understanding before offering a solution. Next time, try starting with, ‘I know you’re under a lot of stress…’ before sharing your thoughts. This pattern has led to more positive outcomes for you in the past.”
Pregnancy: Supporting Your Partner
The Insight: A pregnant woman’s changing body can cause a crisis of identity, requiring specific affirmation that many partners don’t realize is needed.
Sein’s Guidance for Husbands: Instead of generic reassurance, Sein prompts you with what she needs to hear. “Say this: ‘You’re creating life with your body—that’s the most incredible thing I’ve ever witnessed. You’ve never been more radiant.'”
The Result: Your wife feels deeply seen, understood, and loved.
Parenting: Understand Before You React
Q: “My 2-year-old is always running around. Is he just being naughty?”
Sein’s Answer: “You tend to look for the ‘why’ behind the action. Your AI reminds you: this is a ‘motor-sensitive period,’ and running is crucial for developing his sense of balance. Your most successful past approach was to take him to a safe outdoor space to run freely, then gently guide him back to a quiet activity.”

Privacy First
We won’t record every moment indiscriminately, like in the sci-fi films “The Final Cut” or “The Entire History of You.” We want to preserve memories, but we believe those memories should be meaningful—not just an undifferentiated pile of data.
Our goal is to create a biography, not a log.
Our Manifesto
The grip of technology is trying to pervade every corner of our lives. Our phones log our every move in the name of “personalization,” only to trap us in information bubbles.
When “indiscriminate recording” meets “cloud storage,” Pandora’s Box is opened. No matter how much a developer promises, words feel empty. We refuse to let the worlds of “1984” or “The Final Cut” become our reality.
This is why we forged Sein Clip from a different philosophy, built on two unwavering promises. First, it is not designed to record every detail indiscriminately; its purpose is to help you summarize the key points and find the wisdom within your conversations. Second, and most critically, your raw audio is never uploaded to any cloud. It is processed on your device and remains, always, with you.
Specs
As we move through final prototyping and production, some specs may adjust slightly. Both Basic and Pro feature dual microphones. Basic has no MPU, while Pro includes an MPU with 6-axis gyroscope and temperature sensor. Chipsets differ between versions, but no major changes are expected.

Design for Sein
We don’t make glasses, screens, or speakers. Lightweight and unobtrusive, our device frees your eyes. Screenless and silent, it brings you back to the real world—quietly present without ever disturbing.
We deliberately adopted a proven two-part clip design, separating the main battery from the core electronics. This intelligent architecture allows us to maximize endurance with a larger power source, all while keeping the main device incredibly slim, light, and perfectly balanced. It’s an approach we admire, and we’ve refined it for Sein Clip.
Cameras, microphones, and sensors give AI its senses, allowing it to understand you and your surroundings without interfering with your life. All data stays on the device, private and secure—a personal companion you can trust. Light, long-lasting, intelligent—technology that serves your life, never controls it.
