About Us
Crafting a living book workspace that restores deep, focused reading for students, researchers, and book lovers.
Last Updated: February 23, 2026
Our Story and Mission
Granthiva was created by software engineer Sujal Kumar Soni with a single clear mission: to build the world’s most tactile, distraction-free, and intelligent digital reading and study workspace.
In an era where digital reading has fractured across cluttered browser tabs, rigid PDF viewers, and forgotten copy-pasted notes, Granthiva restores the classical reverence of bookcraft. We combine tactile 3D physical book physics with spatial intelligence, authentic margin annotations, and instant multilingual word translation.
Whether you are an undergraduate tackling 1,000-page academic textbooks, a researcher annotating scientific papers, or a lifelong book lover reading classic literature, Granthiva transforms passive scanning into active, joyful comprehension.
What Makes Granthiva Different
We believe deep reading should feel physical, cognitive, and permanent. Key capabilities of our workspace include:
- Tactile 3D Living Book: Experience realistic page-turn curves, authentic paper grain, and physical folios rendered on GPU canvas
- Multi-Format Support: Seamlessly read and annotate PDFs, EPUB reflowable books, Word documents, and text files
- Instant Multilingual Translation: Tap any unfamiliar word or passage to reveal instantaneous English and Hindi definitions
- Cognitive Flashcard Ledger: Automatically convert saved words and highlights into spaced-repetition flashcards for 90%+ long-term retention
- 100% Client-Side Privacy: Your documents, books, and study highlights remain safe on your device without mandatory cloud lock-in
- Continuous Scroll & Split View: Read with continuous vertical scroll, classic two-page spread, or side-by-side split screen for multi-document research
