Choose by task: use Claude for long‑context, high‑fidelity technical polishing; use ChatGPT for cheaper, faster iterations and integrations. Always run RAG over your source docs so outputs include quoted passages + URLs and timestamps. Record every prompt, model/version, and output in document version control (or Git + snapshots) to preserve revision history. Collaborate in Google Docs/Notion with model-generated drafts + human review.
