Transcribes spoken audio streams into timestamped English text using embedded Whisper neural speech recognition models.

Encodes text to Base64 or decodes a Base64 string back to text.

Converts text between camelCase, snake_case, kebab-case, PascalCase, Title Case, and URL slugs.

Converts a color between HEX, RGB, and HSL, and optionally computes the WCAG contrast ratio against a second color.
