Frequently Asked Questions

What AI powers the Harfex AI tools?＋
Harfex AI tools are powered by Claude, Anthropic's AI model (claude-sonnet-4). Claude processes your text and rewrites it according to the requested style or tone.
What styles does the AI style generator support?＋
The AI Text Style Generator supports 12 styles: Casual, Formal, Poetic, Funny, Motivational, Shakespearean, Gen-Z, Academic, Pirate, Haiku, Headline, and Tweet (280 chars).

How is AI different from regular translators?＋
Traditional translators use fixed word substitution rules. The AI tools understand the meaning and context of your text and genuinely rewrite it — producing natural results that simple word maps cannot achieve.
What is the Create Your Translator tool?＋
Create Your Translator lets you build a custom text transformation tool with your own substitution rules. Add as many rules as you need, test in real time, and use three built-in examples (Cat Speak, Pig Latin, L33T) as starting points.
Is AI content accurate?＋
AI outputs are high quality but may occasionally miss nuances. Always review AI-generated content before use in important contexts. The tools work best for creative, social media, and casual use cases.
Do AI tools require an API key?＋
