From “Read” to “Understand”

Languise is an AI document understanding platform that transforms specialized documents—from merely reading them to truly understanding them.

It translates and summarizes PDF, Word, PowerPoint, and Excel files while preserving their layout, and explains foreign patents, English-language papers, and technical materials in plain terms—including figures, tables, and patent claims.

By supporting your understanding of figures, tables, and claims, it greatly speeds up reading foreign documents in research and development, intellectual property, and technical investigation.
