Everything you need to know about Veridect and GPTZero.
GPTZero is a well-known tool, primarily optimized for English text. For French, its performance is limited by the lack of French-specific linguistic markers. Veridect uses 4 signals calibrated for both French and English, offering more accurate detection in both languages.
Veridect is natively built for French with lexical markers, perplexity thresholds, and dysfluence analysis adapted to the French language. It is currently the most reliable detector for French texts, with confidential client-side analysis.
Veridect analyzes 4 linguistic signals: em dash signature (typical of GPT and Claude), AI lexical markers, sentence length variance, and absence of natural dysfluencies. The analysis runs entirely in your browser — your text stays private.
