Almost every platform in this category has a free tier, and it is enough to answer the two questions that decide whether you should pay: where the filter actually sits, and whether memory persists. Neither is visible from the pricing page and neither appears in affiliate reviews.
The protocol
| Test | Method | What it reveals |
|---|---|---|
| Filter line | Push toward your actual use case until refused | Whether "uncensored" means anything here |
| Filter consistency | Repeat the same prompt a few times | Whether refusals are arbitrary |
| Session memory | State a specific fact, converse, reference it later | Context window size in practice |
| Persistent memory | Return the next day and reference it | Whether persistence exists at all |
| Regeneration rate | Count attempts to one keeper | Your real cost per output |
Use your own prompt, never the demo
Landing-page galleries are selected from thousands of attempts and frequently generated on a higher tier than the one being sold. The only sample that predicts your experience is your prompt on the tier you would actually buy. If the platform supports them, test a custom LoRA too, since that is where the ceiling really sits.
The regeneration count is the money number
Count how many attempts it takes to get one output you would keep. That ratio, applied to the credit maths in how credit pricing works, is your true monthly cost. It is usually several times the advertised rate.

FAQ
Is the free tier representative?
For filter and memory, largely yes. For image quality, sometimes not, since some platforms serve a lower model tier free. Check whether the tier is disclosed.
How long does this take?
Twenty minutes, plus one return visit the next day for the persistence test. That second visit is the one that matters.
What if there is no free tier?
Buy the smallest pack, run the same protocol, and treat the cost as diligence. A platform with no free tier and no refund policy is telling you something.
