Deep-Tech · Dual-IMU Sensing + Motion Data · Made in India

One pen writes. One dataset grows. Every page makes the platform smarter.

Two priorities, one loop. The patented Vahini dual-IMU sensor pen writes on plain paper and feels what no camera can see: pressure, pen angle, writing speed and pen-lifts. Every consented page grows the world's first Indic handwriting-motion dataset. This is not a lab project. The analyser is live today, and every new writer makes the platform smarter.

Many products, one motion model

One signal. Six products today. Hundreds tomorrow.

Every product here runs on the same proprietary handwriting-motion dataset and one model. Handwriting analysis is the live proof; each new product both ships value and feeds more motion data back into the moat, so the platform compounds instead of being capped by any single product.

Handwriting Intelligence

20-factor analysis and personalised practice across five Indic scripts, live today.

Proven first in handwriting · Live today

Proof the signal becomes real insight.

Our handwriting solution is live now. Upload any handwritten page and get a 20-factor analysis with personalised exercises, across five Indic scripts. It's the working proof of everything the platform promises.

The asset nobody else holds

India’s consented multi-script handwriting dataset.

Every analysed page and every pen-stroke, captured with explicit consent, builds a corpus that doesn’t exist anywhere else: real handwriting motion across five Indic scripts and many ages. A camera company can scrape finished pages; only Vahini owns the motion behind them.

Consent-firstCollected only with explicit consent, never quietly scraped.
Motion, not contentWe store the signal, pressure control, pen control, writing flow, never the words written.
DPDP-aligned, India-processedPrivacy by design under the DPDP Act 2023, a sales advantage, not just compliance.

The technology

Built on real hardware, on real paper.

The pen reads motion, not the page, so it works on whatever paper you already use.

Dual-IMU sensing

Two inertial units (one 9-axis with magnetometer, one 6-axis) plus a tip force sensor stream 16 axes at 208 Hz, Kalman-filtered.

Works on any paper

No dot-pattern, no tablet, no special notebook. The signal comes from the pen, not the page.

Five-script modelling

Motion models tuned across five Indic scripts, the basis of a consent-first motion dataset.

Patented

Indian Patent No. 584433, DPIIT-recognised.

One pen. Regular paper. Endless signal.
