The short version: replies cost the operator money every time, so a free companion is always paid for by something. There are four arrangements, and which one you are in decides what happens next.
A trial. A fixed allowance of messages, or a fixed number of days, after which the service stops and asks for a card. This is the most honest kind, because the end is visible from the start and you can plan what to spend it on.
An advertising tier. The replies are free and the attention is sold. Worth knowing because the incentive is time spent, and a character designed to keep a conversation going is not the same product as one designed to be useful and let you leave.
A permanently limited tier. Free forever, with something held back: a slower or smaller model, a shorter memory, a daily message allowance, waiting at busy times, or no way to shape the character. Nothing wrong with it — but the free tier is then a sample of the paid one, not the product itself.
A data trade. The service is free and your conversations are used for something: training, human review, or profiling. This can be a fair swap when it is stated, and the place it is stated is the privacy policy, never the marketing page.
A trial that takes your card and a trial that does not are different products wearing the same word. With a card on file, the trial is a subscription with a delay: it renews unless you act, the renewal date is the thing to write down, and cancelling is a task you have to remember. Without a card, the trial simply stops, and nothing can be charged because nothing was given. If a service asks for a card before a single free message, that tells you the shape of the offer.
Most trials are short enough that idle chat uses them up without settling anything. A better use is to test the things that would make you cancel later, in this order:
Five questions, a handful of messages, and you know more than any review page can tell you.
If what you want is to see what one of these is like, a free tier answers that completely and you can stop there. Paying starts to make sense for one reason only worth stating plainly: continuity — a character that keeps what you told it and is the same one next week. If the free tier already forgets between sessions, paying is the thing being tested, so test it against the limit rather than the marketing.
Everything above applies to any service, including this one, so here are the same answers for the companion on this site, in the same terms.
