Document flow or finished work output?
For Claude, test how well substantial sources, working drafts and, where relevant, repository context can be handled in a traceable flow. For ChatGPT, also test how analysis, tools and delivery of a usable artefact work together.
Boundary: product access and data path
Governance is not determined by the brand name. Check the subscribed plan, enabled connectors or apps, retention, training use, identity controls and export path for this exact workflow.
Pilot: one source pack, two target artefacts
- Use the same redacted source pack and role instructions
- Produce one long-form output and one finished work artefact
- Measure source coverage, corrections, export and repeatability
- Document plan and data-path assumptions alongside the result
Decision matrix
| Criterion | Claude | ChatGPT |
|---|---|---|
| Document context | Test long sources and working drafts with fixed review points | Test source work together with tool and output steps |
| Work artefact | Check how the result enters the next process | Check whether format, export and further editing fit |
| Operating boundary | Record plan, connectors and Claude Code permissions | Record plan, apps, tools and workspace permissions |
Keep it verifiable
