Turnitin AI Report Checker in Spain: Check Before You Submit

Spanish was one of the first languages after English to get Turnitin AI detection, launched in September 2024. That means a Trabajo de Fin de Grado (TFG) or Trabajo de Fin de Master (TFM) written in Spanish can receive an AI score as well as a similarity report.

What Spanish-language detection covers

• Spanish: AI writing percentage and highlighted sentences, through Turnitin Originality.
• English: the full check, including AI-paraphrase detection.
• Catalan, Basque and Galician: not supported for AI detection. Similarity checking still works.

TFG and TFM length

Turnitin's AI detector accepts 300 to 30,000 words per file. Most TFGs fit. A long TFM or doctoral thesis may need to be checked in parts, chapter by chapter.

Who in Spain should check first

• Students finishing a TFG or TFM in Spanish.
• Students in English-taught and bilingual degrees.
• Erasmus students submitting to host universities that use Turnitin.
• Anyone who used AI tools to translate between Catalan, Spanish and English.
