Getting Clean Text Out of PDF, DOCX, and HTML

For AI engineers building document-centric applications, your biggest bottleneck isn't the model—it's getting truly clean text. While generation is increasingly commoditized, the real engineering challenge lies in robustly extracting properly ordered content from files like PDFs, which inherently lack semantic structure. Underestimating this complex preprocessing step can derail your AI projects, highlighting that solid data extraction is often harder than the 'solved' AI problem.
