Text Capitalizer

This tool standardizes capitalization across text by applying sentence case, title case, all caps, or lowercase conversions. It preserves punctuation and spacing while transforming word shapes. Conceptually, the input text is parsed into tokens, capitalization rules are selected, and each token is transformed according to the chosen mode. The process is non destructive in the sense that it does not alter non alphabetic characters beyond punctuation spacing. The tool is valuable for writers, editors, marketers, software engineers, and localization teams who produce headers, emails, documentation, or UI copy. Unique value lies in handling common edge cases such as acronyms, initialisms, and inline punctuation, plus locale-aware title capitalization rules in many languages. Core features include multiple target cases, automatic normalization, and a lightweight API interface for batch processing. Typical use cases include converting article sections to title case, normalizing headlines, or ensuring code comments follow a consistent style. Outputs are plain text strings ready to copy into documents, CMS, or source files. This tool emphasizes accuracy, speed, and predictable results, making it suitable for daily editorial workflows and development pipelines.

It does not generate formatted documents or files; it focuses on pure text transformation with clear, deterministic rules.
