The decision to make
Editorial judgment: grammar suggestions need editorial judgment, especially for names, technical terms, voice, and deliberate style choices.
The caution is Atlas editorial judgment about evaluation—not a measured product defect.
Does the revision preserve the meaning and voice you intended?
Use the evaluation guide ↗Access, plans and data
Check the current policy and your plan before connecting sensitive data.
Confirm administration and access controls for your intended plan.
Check current plans and usage limits at the official source. Price amounts and plan-specific entitlements were not independently verified in this expansion.
A small first test
- Pick one representative job and define a result you can check.
- Use non-sensitive test material and limit the connections you authorize.
- Inspect the result and the effort required to correct or export it.
- Compare against your existing process before expanding the rollout.
