01

Match case to purpose

Human-facing titles usually need readable capitalization, while code identifiers and machine-readable values benefit from predictable case conventions.

02

Keep slugs stable

Use simple lowercase words and consistent separators. Avoid unnecessary punctuation or formatting that can create fragile or confusing URLs.

03

Preserve the meaning

Cleaning should remove formatting noise without changing important names, numbers or the actual meaning of the source text.

Smart Case & Slug Sanitizer FAQ

What can Smart Case & Slug Sanitizer convert?

It can create title case, sentence case, lowercase, uppercase, camelCase, PascalCase, snake_case, kebab-case and sanitized URL slugs from the same source text.

What makes a slug URL-safe?

A practical URL-safe slug generally uses simple lowercase text, consistent separators and excludes characters that are unnecessary or problematic inside a URL path. The local sanitizer applies those rules automatically.

Does the sanitizer remove numbers?

You control that behavior. Numbers are preserved by default because dates, versions, quantities and model names can carry important meaning.

Does the normal converter send my text to AI?

No. Case conversion and slug sanitization run locally in your browser. Text is sent to the ToolItFast AI service only if you deliberately choose Refine with AI.

What does the AI option add?

The optional AI layer evaluates readability, meaning preservation and slug quality and can suggest a clearer human-readable label, cleaner slug direction and relevant alternative names.
