Technical Features

Automatic Boundary Recognition

Tool intelligently recognizes the following boundaries and adds spaces:

• Chinese character + English letter
• Chinese character + number
• English letter + Chinese character
• Number + Chinese character

Preserve Original Format

• Does not modify original wording, punctuation, or line breaks
• Existing spaces will not be duplicated
• Spaces within English words and numbers remain unchanged

Notes

• Tool only processes spaces, does not modify text content or punctuation
• Very large texts (tens of thousands of characters) may cause slight browser rendering slowdown, recommend processing in segments
• For proper nouns or special formats requiring preservation, manually adjust after optimization

Comparison with Similar Tools

Compared to manual typography, automated tools can save over 90% of time cost. Compared to simple find-and-replace, semantic boundary-based intelligent recognition is more accurate, avoiding misoperations. Suitable for creators, editors, and developers who frequently handle Chinese-English mixed content.

Usage Tips

• For documents containing code snippets, recommend extracting code blocks first, only optimize descriptive text
• When batch processing multiple files, test single file first to confirm effects, then batch upload
• Optimized text can be directly pasted into Markdown editors, CMS backends, or rich text editors
