caixuan.cc — branded 彩漩PPT — is a presentation platform from Beijing Caixuan Technology that treats a slide deck as a living document rather than a file. The workflow starts with AI-assisted creation: you provide the ideas and structure, and the platform helps generate and beautify slides, claiming to cut formatting and design work by a large margin. PPTX files are preserved losslessly so online and local versions look identical, and version history is kept so any earlier state can be restored.
Collaboration is the second pillar. Team members are assigned pages, can comment directly on a region of a slide, and see changes reflected in real time across desktop, mobile and a PowerPoint plugin. Because every version is retained, teams avoid the familiar problem of multiple conflicting copies of the same deck floating around.
The sharing layer is aimed at people who distribute content commercially — trainers, consultants, salespeople. Decks in PPT, Keynote or PDF can be converted into H5 pages that open in a mobile browser, with password protection, watermarks and paid reading options to protect copyright. Sharing is an alias for analytics: creators can see who opened the deck, which pages held attention, and how long readers stayed, turning a presentation into a lead-signal channel. A Tencent Meeting integration and a mini-program for distributing courseware round out the offering.
