Use cases

Collaborative Academic Research

Turn your research projects into true collaborative experiences. Teams of historians or scholars can import digitized manuscripts and archives, explore them together, and enrich documents with shared annotations. The result: faster progress, better traceability of analyses, and richer collective scientific output.

Showcasing Cultural Collections

Give your collections a new life. Museums, libraries, and cultural institutions can bring their artworks online, organize them, and add annotations to create interactive experiences. Audiences and researchers gain easy access to content, presented in a modern way and fully compliant with IIIF standards for visibility and long-term value.
