Redmi Smart Pen

Unleash your creativity anytime, anywhere with the Redmi Smart Pen — Redmi’s first active stylus designed for smooth handwriting, precise sketching, and effortless productivity. Built with an ergonomic grip and a premium matte-white finish, it delivers a natural pen-to-paper feel that makes writing and drawing more intuitive than ever.

Powered by Xiaomi’s proprietary smooth-prediction algorithm, the Redmi Smart Pen offers millisecond-level ultra-low latency and 4096-level pressure sensitivity, accurately capturing every light stroke, shade, and curve. With a 10g activation force and dual pen-screen optimisation, lines remain fluid and responsive whether you’re taking notes, annotating documents, or illustrating detailed artwork.

The pen supports a 240Hz touch sampling rate and 120Hz refresh rate while writing*, dramatically reducing input lag and improving stroke accuracy on compatible devices. Combined with up to 12 hours of continuous writing, it’s built for students, professionals, artists, and digital creators.

Two multifunction shortcut buttons make everyday tasks faster and smarter — open Mi Canvas instantly, switch brushes or colours, capture screenshots, or flip through pages and documents with a simple tap. And when inspiration strikes, the Redmi Smart Pen lets you write even when the screen is off, waking the display directly into a full-screen canvas.

Optimized for leading third-party drawing and note apps, the Redmi Smart Pen delivers smoother strokes, one-stroke drawing response, and reliable text recognition — making it the perfect companion for your Redmi or Xiaomi tablet.
