Sinai.ai is an Egyptian startup reimagining the book as an interactive, AI-native medium rather than a static file. At the center of its product is aiBook, a patented format that transforms full-length, licensed books into experiences readers can talk to: ask a question mid-chapter, request a tailored summary, generate quizzes and study guides, visualize a concept, or switch seamlessly between reading text and listening to audio. The goal is to make deep reading more engaging and to turn passive consumption into active, personalized learning.
A defining choice is Sinai's content model. Instead of scraping the open web or operating on snippets, the company sources 100 percent licensed, full-text content directly from publishers and rights holders. This lets its AI reason over complete works while keeping the platform on legally solid ground, an increasingly important differentiator as publishers grow wary of unlicensed AI training and retrieval. It also opens a partnership channel: publishers gain a new interactive distribution format for their catalogs.
The platform supports multilingual access, allowing readers to engage with titles across several languages, and multimodal consumption that blends text, audio, and generated visuals. That combination is particularly relevant in markets where audio-first and mobile-first habits are common and where multilingual demand is high.
Sinai.ai was founded in 2024 by Ahmed Kamel, Mohamed Elshamy, Mohamed Elshenawy, Hana Malhas, and Abdullah Moatasem. In April 2026 the company closed a 1.45 million US dollar pre-seed round led by KAUST Innovation Ventures and DisrupTech Ventures, with participation from Maza Ventures, YOUXEL Ventures, and angel investors. The funding supports technology development, AI infrastructure, content licensing, and user acquisition as the platform moves out of its exclusive beta toward broader availability.
