Hi Product Hunt! 👋 We’re Kamlesh and Rakesh, the makers of Snowfairy AI OS Pen. We built OS Pen to solve a common frustration: presenting, teaching, explaining, and recording ideas often requires switching between several disconnected tools. We wanted one focused workspace that stays accessible over any Windows or Android screen. With OS Pen, you can: ✍️ Draw, highlight, and annotate over any application 📐 Use precision drawing and measurement tools 🖥️ Turn your screen into a flexible digital whiteboard 🎥 Capture screenshots and record your screen 📄 Export your work as professional PDFs 🤝 Collaborate with nearby devices over local Wi-Fi OS Pen is designed for teachers, presenters, trainers, creators, remote teams, and anyone who communicates visually. The Windows version is available through the Microsoft Store and our official website, and OS Pen is also available for Android devices. 🎁 Exclusive Product Hunt launch offer The first 500 Windows users will receive 30 days of OS Pen Premium, while the first 500 Android users will receive 30 days of OS Pen Pro — completely free, with no credit card required. Redeem the launch code within 14 days of launch. Your 30-day access begins when the code is redeemed and automatically returns to the free plan when the promotional period ends. We’d genuinely value your feedback — especially on the onboarding experience, annotation workflow, and the features that would make OS Pen more useful in your daily work. Thank you for exploring OS Pen. We’re excited to hear what you think! 🚀
