The Problem with Raw PDFs in AI

When you upload a scanned or heavily formatted legal contract directly to Claude or ChatGPT, the AI uses OCR or basic text extraction. This process often jumbles the text, merges columns inappropriately, and includes irrelevant metadata. If you're asking Claude to identify missing indemnification clauses, poor text formatting can lead to critically incorrect answers.
