One pen · one signal · many markets

The pen is the core. Each market is the same signal, put to work.

Vahini came first: screen-free, paper-based, motion-aware. The 20-factor analyser exists to back the pen with a product people can use today. From there, the same motion signal reaches market after market, no new hardware, no new data.

VahiniThe core

A dual-IMU sensor ballpoint that writes on ordinary paper and records the motion of every stroke at 208 Hz, screen-free.

The source every market below draws from · Patent No. 584433

HandwritingLive today

20-factor analysis & personalised practice across five Indic scripts, the product that backs the pen.

Coaches, parents, students & schools

Digital notesIn build

Class notes written on paper, reconstructed from the IMU signal into a digital page. No tablet, no app open, no screen-time.

Students, schools & anyone who thinks better on paper · our founding idea

Assistive & screeningResearch

Support for writing difficulty and the early motor signals behind it, studied with clinicians, never a standalone diagnosis.

Special schools, occupational therapists, accessibility & research partners

The datasetThe moat

India’s consented, multi-script handwriting-motion data, a defensible asset and a future licensing line.

What makes every market above hard to copy

Markets shown to illustrate scope; size each with primary research before external use.
