Common questions
Is one of them clearly the best?
No. Reviews disagree and the models change quickly, so the useful test is your own task. Run the same prompt through two of them and compare how much editing each result needs.
Do I need a paid plan?
Start free. The review we checked puts all three paid plans at about $20 a month in US pricing, so upgrade only when you keep hitting usage limits.
Can they do research?
All three can search the web. Open the cited links before you rely on any claim, because summaries can still be wrong.
