238
+ <ol>
239
+ <li><strong>Paste your text:</strong> Copy and paste AI-generated text into the input box</li>
240
+ <li><strong>Choose style:</strong> Select Natural, Casual, or Conversational based on your needs</li>
241
+ <li><strong>Set intensity:</strong> Adjust how much humanization you want (0.1-1.0)</li>
242
+ <li><strong>Click Humanize:</strong> Process your text and see the results</li>
243
+ <li><strong>Review changes:</strong> Check the similarity score and changes made</li>
244
+ </ol>
245
+
246
+ <h4>💡 Tips</h4>
247
+ <ul>
248
+ <li><strong>Natural (0.5-0.7):</strong> Good for professional content that needs to sound human</li>
249
+ <li><strong>Casual (0.6-0.8):</strong> Perfect for blog posts and informal content</li>
250
+ <li><strong>Conversational (0.7-1.0):</strong> Best for social media and very informal content</li>
