Detector de IA is a free AI text review tool that prioritizes Spanish while also offering an English interface. Users can paste 300 to 100,000 characters, or view text extracted from PDF, DOCX, TXT, MD/Markdown, and plain text files. After running a detection, they can view probability scores, risk alerts, evidence strength, and sentence-level highlights, copy the summary, or export a printable report. Results are intended to assist with manual review; false positives or false negatives may occur, so they should not be used alone for high-stakes decisions such as academic, hiring, or disciplinary matters. Uploaded files must be under 12 MB.
