OmniBox, known in Chinese as Xiaohei, is a personal knowledge base powered by AI. You can send it text, voice notes, images, files and links, including through WeChat or QQ, save web pages from your browser and follow RSS feeds.

It reads PDFs, Word and PowerPoint files, runs OCR on scans and transcribes audio and video so everything becomes searchable. You can then ask questions with cited answers, or turn notes into summaries and reports. The interface is mainly in Chinese.
