Enterprise & Developers

Bring the Visual Key and Chinese-character data into your product.

Clavis Sinica owns a complete original Chinese-character technology stack: the Visual Key input engine, a structured character database built on the Three-Script Theory (components, etymology, pinyin, stroke order and semantic relations for 14,000+ characters), and an end-to-end content production pipeline. We license these to enterprises and developers.

Ways to work together

• Visual Key licensing: integrate "see-it, type-it" input into your app / IME / education platform.
• Hanzi data API: etymology breakdown, component structure, visual lookup, atlas generation (see API).
• Custom content: bulk-produce atlases, flashcards and picture books for your platform.
• Joint products: build on our master database with your distribution.

Our Visual Key was unveiled at the 2024 "Chinese Visual Input Method Global Launch" in Dubai and praised by linguists. This capability — an original theoretical system plus a proprietary master database powering end-to-end character products — is uncommon in the field.
