The Diagnosis Problem
The bottleneck isn't practice.
It's diagnosis that can't scale.
India's K–12 students lose board exam marks over illegible, slow, or inconsistent handwriting. Yet a coach can grade only 15–20 sheets a day. Imported smartpens cost more than a month's school fees and don't read Telugu or Tamil. The result: 200 million students stuck with paper checklists and weeks-long turnarounds. Our research, including a positive demo at IIT Hyderabad, confirmed the bottleneck is objective fast diagnosis — not more practice sheets.

Five Indian Scripts at Production Accuracy
English, Hindi, Telugu, Tamil, and Kannada — validated on a live AI pipeline. No existing coach platform serves Telugu, Tamil, or Kannada handwriting writers. Vahini's 18–24 month lead in this segment is built into the training data, not the roadmap.
NCERT-aligned scoring
DPDP Act 2023 Compliant by Architecture
Images are destroyed the moment analysis completes. All processing runs on Indian GCP regions. School-level Fernet-encrypted storage ensures the institution stays in control of its data. Imported solutions cannot achieve this without full re-architecture.
Zero image retention · Indian data residency
18–24 month defensible lead in the Indian handwriting intelligence market.

Privacy and Compliance
The signals get smarter. Your data stays yours.
Zero image retention
Handwriting images are used only for analysis and automatically deleted the moment the report generates. Nothing is stored.
Indian GCP data residency
All processing runs on Indian cloud regions. DPDP Act 2023 data-localisation requirements met by architecture, not workaround.
School-level Fernet encryption
Student data encrypted at rest with institution-level keys. The school controls deletion. No ad targeting, no third-party sharing.
Evidence behind every insight
Each AI recommendation is tied to a measurable signal — pressure, jerk, pause, or stroke pattern — not a black-box guess.
