Use Claude for the heavy lifting — it’s built for careful analysis and long-context work, so it handles 50k+ token collections better for accurate paraphrases and citation binding. Practical workflow: chunk texts with overlapping windows, tag each chunk with a stable source ID, produce a single citation table (source ID → full reference), and request paraphrases that include the source ID and quoted offsets. Always validate paraphrases against original passages.
