How we test
Every review on this site is scored on the same axes, and every price we quote is checked against the brand’s own pages. This page explains exactly how, including the parts we are still documenting.
The protocol
Each review shows who reviewed it and, once confirmed, the date of the last test. When a review is updated after publication, its “Updated” date changes with it.
The four scoring axes
Every tool gets a score from 0 to 5 on the same four axes.
- Realism: how convincing the images, chat and voice actually are.
- Uncensored: what the tool truly allows, compared with what it advertises.
- Privacy: what you have to hand over to sign up, what gets stored, how billing appears on your statement, and what the privacy policy actually commits to.
- Value: what the free tier really gives you, and whether the paid plan earns its price once add-ons such as tokens or credits are counted.
The overall score
The overall score out of 5 is an editorial judgment informed by the four axes. It is not a mechanical average, so it can sit above or below the mean of the four axis scores: a standout feature can lift it, and a single serious problem, such as billing practices or a privacy red flag, can pull it down. The rankings on the site are ordered by this overall score, with one tiebreak from our safety grid, below.
How prices and features are checked
Prices, plans, token costs and refund terms change often, and they are where readers lose the most money. From September 2026, every price, plan detail and policy we quote in a new or updated review is checked against the brand’s official pages: the pricing page, help center, terms of service or privacy policy. We record the source and the date it was checked. If something cannot be verified on an official page, we don’t state it.
Safety grid
Before a tool can be ranked, we check its official pages (site, help center, terms and policies) against the criteria below. What we find goes into the dated “Safety & billing check” box at the top of each review, with a source for every line: age verification, rules on real people, photo uploads, and how billing, renewals and refunds work.
These exclude a tool. An excluded tool is removed from every ranking and we don’t link to it. If we had already reviewed it, the review stays online with a “Not recommended” notice that gives the reason.
- An “undress”, “nudify” or similar feature that works on a photo you upload, even behind a consent checkbox.
- Uploading a photo to reuse a face, or face swap, when nothing checks that the face is yours. Sharing a photo in a chat only for the AI to look at doesn’t count.
- A content policy we can’t find, or one that doesn’t explicitly ban minors and the use of real people without their consent.
- Characters based on real people who haven’t consented.
These add a visible warning. The tool can still be ranked, and a ⚠ next to its name links to the details in its review.
- An “undress” or similar feature limited to characters generated on the platform, or to doubles of real people whose identity and consent are verified, with no way to upload an outside photo.
- Face upload limited to your own face, checked against an ID or a matching selfie.
- Tags, categories, age options or promoted content framed around youth, even when labeled 18+.
- Characters based on real people who have consented and been verified, such as official “digital twins” of creators.
Ranking. When two tools have the same score, or scores 0.2 points apart or less, the tool without a warning ranks first.
What affiliate links change, and what they don’t
Some links to the tools we review are affiliate links: if you sign up through them, we may earn a commission at no extra cost to you. They fund the site. They do not change a score, the order of a ranking, or what a review says about a tool’s weaknesses. Every review lists the downsides we know about, including billing traps and privacy concerns.
Our one hard rule
We only list tools for original, fictional characters. We do not rank or link to any tool that can undress or fake real, identifiable people (see the safety grid above).
