B.Lexia, a hardware-free multimodal web platform for early dyslexia pre-screening in children aged 6 to 12, requiring no specialised equipment. Three biometric analysis modules are integrated: oculomotor eye-tracking (AUC = 0.933 under LOSO cross-validation), acoustic speech classification (AUC = 0.918, accuracy 84.2 %), and handwriting recognition via an alpha-blend fusion mechanism (AUC = 0.999). A weighted decision engine fuses the probability scores from the three modules to produce a risk verdict and a structured clinical report in PDF format, generated by Gemini 2.5 Flash and ReportLab
