Official siteA general assistant can help write, explain, analyse or prepare a task. Its usefulness depends on the prompt, human review and the data you provide.

Draft an outline or a summary for review using documents you are allowed to share.
Explore alternative wording and objections before a human decision.
Explain a concept, then verify factual claims and references separately.
Run the same task in two assistants with a clear expected outcome.
Check how you can attach, export and delete files.
Count errors, omissions and correction time rather than judging fluency alone.
Starting situation. Turn three meeting notes into a one-page summary for colleagues who were absent. Use non-sensitive notes containing one disagreement and one decision that remains open.
Give two assistants identical notes and an identical output format. Ask them to separate decisions, open questions and assigned actions.
Compare every sentence to the notes. Count invented decisions, lost qualifications and actions assigned to the wrong person.
Choose the service that makes correction and export practical, then review data handling before using real meetings.
These active services are starting points from the directory. Editorial highlighting and score order this selection; they do not replace a trial on your own task.

Official siteNo. For citable references, a large corpus or a strict output format, compare a specialist document or research tool too.
Try at least one revision: the assistant should incorporate a new instruction without losing information you already approved.
Use fictional or approved material. Keep contracts, personal data and business secrets out until data handling is understood.
