Short answer: Claude tends to be more conservative and handles long legal contexts with fewer fluent hallucinations; it preserves quoted paragraphs and follows strict citation instructions better. ChatGPT is faster for short summaries but more prone to producing confident-sounding, inaccurate citations unless you supply the exact source snippet. Practical workflow: run exact-text retrieval (OCR PDFs), feed only the target paragraph to the model, ask for verbatim quote + paragraph locator, then verify against the primary source.
