AionUi is a Chinese micro-publisher that concentrates on wrapping large-language-model power in discreet Windows utilities rather than sprawling suites. Its catalogue is intentionally narrow: two applications that sit quietly in the taskbar until summoned. The flagship 海鹦OfficeAI助手 (Haiying OfficeAI Assistant) embeds directly into Word, Excel and PowerPoint ribbons, offering paragraph rewrites, formula suggestions, slide outline generation and bilingual polish without pushing documents to the cloud. Companion tool AionUi for Gemini CLI re-packages Google’s Gemini model as a local, open-source canvas where users can spawn parallel chat threads, diff code snippets, index project folders and batch-convert Markdown to polished reports. Typical workflows include students refining thesis chapters, finance teams stress-testing spreadsheet logic, and developers comparing iterative code reviews in a split-pane view. Both programs share a common philosophy: keep the interface minimal, store data offline by default, and update through silent background pulls. Because the components are lightweight, they are frequently installed together on shared office laptops or classroom imaging scripts. AionUi software is available free of charge on get.nero.com, where downloads are delivered through trusted Windows package sources such as winget, always fetch the newest build, and can be queued for unattended batch installation.
