Most AI humanizers just swap synonyms — detectors see right through them. Temiz Metin uses deep semantic rewriting to change the actual linguistic fingerprint of AI text. Same meaning, completely different structure. Tested against 5 detectors: • Turnitin: 94% → 6% • GPTZero: 89% → 3% • Copyleaks: 81% → 4% Works for both English and Turkish — most tools are English-only. First 100 words free.
