Zhiwen is an AI online document generation platform from iFlytek, built on its Spark cognitive large model. Users only need to enter simple topic keywords, an outline, or long text (up to 12,000 characters) to generate complete PPT and Word documents in one click, greatly lowering the barrier to document creation.

Key features:

Smart document generation: Multiple input modes — topic creation, text parsing, audio/video transcription — automatically generate structured PPT and Word documents
AI writing assistant: Editing operations including copy polishing, expansion, splitting, and translation, with mutual translation across 10 languages including Chinese, English, Japanese, and Korean
AI auto-illustration: Intelligently matches relevant images to the text content, enriching visual presentation
Quick template switching: Diverse layout templates and color schemes, freely editable online
Web search: Real-time retrieval of the latest material keeps content current

Use cases: For business reporting, users can quickly generate professional presentations; in academic research, researchers can turn paper outlines into structured academic reports; in education and training, teachers can auto-generate teaching courseware from course key points. The tool is completely free: new users get 1,000 credits at registration, and each generation consumes 50 credits.
