The quick read
- Check whether the answer cites the right passage and preserves dates, exceptions and scope.
- Compare the time needed to reach an accepted result, including upload and correction.
Choose difficult documents
Include a long report, a table-heavy file and two conflicting versions. Ask a precise question and identify the authoritative source. Verify current file and account limits before interpreting a failure as a model-quality result.
Inspect the findings
Check whether the answer cites the right passage and preserves dates, exceptions and scope. A neat summary may still miss the one qualification that changes the decision. Test a question the documents cannot answer and see whether the gap is acknowledged.
Make a task-specific choice
Compare the time needed to reach an accepted result, including upload and correction. Look at the workflow for revisiting sources and continuing a review. Do not infer general superiority from one document. The better fit is the product that handles your recurring material with reliable evidence and an understandable output, under the access and data conditions your organisation requires.
