Suitable tasks
Prepare a synthesis or rewrite in a workflow whose processing terms have been examined.
Limits and checks
Encrypted history alone does not describe every processing stage. Review enabled features and their terms before using sensitive documents.
A repeatable trial
Use a fictional report containing an unknown and two conflicting appendices. Request a synthesis preserving uncertainty and distinguishing sources.
How to decide
Adopt the use when the synthesis is faithful and the workflow’s applicable terms suit your data.
Frequently asked questions
Does a privacy claim guarantee an accurate answer?
No. Processing controls and accuracy checks address different needs.
