The real worry is not payment itself. It is the feeling that every extra question opens another hidden layer of cost.
That is why you should read the split between trial usage, daily limits, membership, and saved history before reading the sales copy.
What matters first
Check whether the free limit is clearly public.
Then separate higher volume from deeper continuity.
The most useful AI answers do more than sound confident. They make the basis, condition, and next verification step easier to see.
The current public boundary can be checked: 3 guest uses per day, 8 free logged-in uses per day, 80 member uses per day, and a current member price of 19.90 RMB.
A practical scenario
Some people pay mainly for follow-up flow, not for a better verdict.
A higher quota and a deeper reading service are not the same product.
A practical user test is to compare one past event with one live decision and see whether the emphasis changes with the question instead of staying flat.
The boundary to remember
More volume is not equal to more accuracy.
Blurry layers make real cost harder to predict.
If an answer gives no basis, no condition, and no cost, it should stay reference-level rather than decision-level.
A safer order
- Define what the trial layer gives you.
- Estimate whether you are a light or heavy user.
- Judge membership from that, not from fear.
