One account for your work
STHBox is operated by 上海盛迭信息科技有限公司 (Sundear). We bring document processing, presentations and surveys into personal and business workspaces. Teams can share authorized applications, storage and credits.
Products built around everyday tasks
CaseDeck organizes proposals, reports, talks and case collections, with codes for shared presentations. Check the product page for integration availability.
Surveys support design, collection periods, links, QR codes, posters, response analysis and exports.
PDF and OCR tools edit, organize and convert PDFs, recognize scanned documents and images, and export reviewed content. Complex tables, fonts and layouts may not be fully preserved.
File Converter covers documents, images, audio, video, MIDI, vectors, ebooks and fonts. Supported conversions and limits depend on the selected file and available options.
Understand access and usage
Subscriptions define capabilities and quotas. Some actions also cost credits, quoted before processing. Business members use shared resources within their permissions. Files and processing records belong to their respective workspaces; unavailable and test features are identified where offered.
