Rafiq
German practice assistant for Arabic- and English-speaking users, combining voice and text input, German examples, Arabic or English explanations, and separate German speech playback.
Open experimental demo → Browser audio · Local analysisMicCheck
Browser-based microphone quality analysis that records a short sample locally, measures clipping, level, noise floor, and room echo, then returns a grade and a prioritized improvement.
Public repository → PDF repair · Batch processingPDFCleaner
Structural-first PDF repair that preserves text/vector content, validates repaired output, avoids destructive rewrites, isolates failures in large batches, and packages as a drag-and-drop Windows utility.
Public repository →Photo Metadata Repair Inspector
Photo-library inspection and repair tool for comparing filesystem and EXIF timestamps, surfacing inconsistencies, deriving dates from filenames, and applying targeted metadata corrections.
