NSFW AI girlfriend glossary

Twelve terms that come up in adult AI apps' rules, age checks and billing, each linked to the page where it matters.

Answer in brief

NSFW means adult content, ERP is erotic roleplay, and a filter is what blocks it on apps that do not allow it. Age verification and age assurance are the checks apps use to confirm you are an adult. heyGF.AI, our editorial choice, is for adults only and runs as a web app you can add to your home screen.

This page describes policies, not content. It is for adults 18 and over.

Content and rules

NSFW
"Not safe for work": adult content of any kind. An app either allows it for adults, filters it or bans it. Which apps allow it.
ERP
Erotic roleplay: adult roleplay in chat. Kindroid lists it, with NSFW, under what its guidelines explicitly allow; Character.AI bans pornographic content. Which apps allow ERP.
Filter
Software that stops the AI from producing what an app does not allow, by blocking or rewriting replies. Kindroid says it puts no filter on the AI itself. Character.AI says asking for its NSFW filters to be removed will result in a ban. Filters compared, app by app.
Content policy
An app's written rules on what is allowed, usually spread across its terms of service and its community or moderation guidelines. Read it before you pay. What NSFW apps don't allow.
NSFW toggle or marking
A setting or label that keeps adult content separate. SpicyChat requires chatbots with explicit language or imagery to be marked NSFW, and its conversation images follow an NSFW mode.
Lookalike or deepfake
A character, image or video made to resemble a real person. Candy AI bans content resembling real persons, and OurDream bans deepfakes and lookalikes of real people.

Age checks

Age verification
A check that you are an adult before adult content opens, by selfie, ID, payment card or email. Required in some countries and US states. Who checks, where and how.
Age assurance
The wider term for any method of establishing age, from estimating it from a selfie to verifying it from an ID. Character.AI uses it for the check every user must complete, run with Persona.
Yoti
An age-verification company. Kindroid uses it for accounts its systems flag: a selfie age estimate or a government ID.

Apps and billing

PWA (web app)
Progressive web app: a website you can add to your home screen so it opens like an app. heyGF.AI, Candy AI, Secrets AI and OurDream work this way. Why adult apps skip the stores.
APK
An Android app file installed from outside Google Play. SpicyChat's Android app comes this way, from its own site.
Billing descriptor
The name a charge shows on your card statement, which can differ from the app's name. Secrets AI's wiki says its charges show as "S LABS INC". Privacy and discretion.
