Text Tools Tools
Manipulate and analyze text content. All tools run entirely in your browser — nothing is uploaded, nothing is stored.
Text tools manipulate and analyze string content for writing, development, and data cleaning. Case converters transform naming conventions between camelCase, PascalCase, snake_case, kebab-case, and more for cross-language compatibility. Markdown previewers render GitHub-flavored Markdown with live HTML output for documentation and README files. Diff checkers compare text side-by-side highlighting additions, deletions, and changes for code review. Regex testers validate patterns with real-time match highlighting and group capture. Word counters track words, characters, sentences, and reading time for content optimization. All processing is client-side with no data uploads.
