The idea
Choose a tool by testing the work you need it to do. A polished demo may hide weak source links, missed pages, or hard-to-export results. A model's score on a general test may not predict success on your file.
What to check
Give each candidate the same public or fictional records and the same task. Write the expected answers first. Include a missing fact, a disputed date, and a question the records cannot answer.
Compare errors, missed facts, source access, and the time needed to review the result. Check data terms, cost, and firm approval too. Speed alone is not success.
Try it
One tool drafts fast but invents a date. Another takes longer and marks the date as unknown. Which performed better?
Check your understanding
For this task, the second preserved the record's limit. You still need more tests before choosing a tool. Record the version and settings so the result can be checked again after changes.
