Nastia AI Review: free uncensored sexting with rules that actually make sense

What the chat is like

Nastia pitches itself as the place to land after Replika and Character.AI said no, and its landing pages are packed with side-by-side tables against mainstream bots that refuse intimate topics. What you get is a text-first companion you design yourself, picking name, look, personality, voice and backstory, with chats that stay private to your account.

Beyond your own creation there is a public catalogue of more than 98 characters, nearly all taken from anime, manga and games: Yor Forger, Nico Robin, Misato Katsuragi, Levi, Spike Spiegel and a long list of villains. Every one we spotted is an adult in the source material. Group chats let you drop up to 10 companions into one conversation and watch them bicker.

Memory is the headline promise, and the pitch wobbles. The girlfriend page says she remembers your inside jokes forever, while the Nomi comparison page talks about details kept for up to two weeks, plus a custom backstory and shared notes you can feed her. Your messages can run to 850 characters, long enough for proper roleplay turns.

How far it goes (NSFW rules)

Very far, by design. Nastia markets uncensored sexting, dirty talk, explicit roleplay and a nude AI girlfriend who sends pictures on request, and the sex chat page insists the free tier is explicit from the first message. If you are tired of bots that fade to black, this is the opposite.

The content rules are short and clear. Fictional sex between adults is allowed. Banned: anything that suggests a character under 18, including characters drawn young or officially aged up, real or famous people, sleeping or drunk partners, scenes where someone does not agree, animals, extreme violence and trafficking. Requests and generated media are screened automatically, and you can ask for a human review if your account gets restricted.

Pictures, voice and video

Your companion sends selfies in chat, in 4K on the Unlimited plan, and a separate generator offers pose control and image-to-video, with HD video and video messages kept for paid plans. The compliance page is reassuring here: photo and video uploads are switched off, face references can only come from images Nastia generated itself, and prompts naming public figures are refused.

Voice is part of the deal too. Companions answer with voice messages in a custom voice, and the comparison page says you can upload your own audio file to shape it. One snag: the homepage FAQ lists voice chat among the paid extras, while the sex chat page says voice messages come with every plan, free included. You will only know which is right once you sign up.

What it costs

The clearest price sits on the sex chat page: Free at $0 with daily token limits, and Unlimited at $15.99 a month with no message caps, unlimited 4K selfies, voice, 1080p video, unlimited companions and voice cloning. The membership page itself only loads inside the app, and testimonials mention a Standard plan that no page we read puts a price on.

Other pages muddy the water. The Nomi comparison still advertises plans from $6.69 a month and a Pro plan at $49.99 a year, about $4.17 a month. We cannot tell whether those are older prices or a separate offer, so check the in-app checkout before trusting any figure. The terms add that sales tax may come on top, prices can change at any time and everything is billed in US dollars.

The free plan is usable on its own: one companion, uncensored text and basic customization, with no card and no expiry date. The catch is a daily token allowance that the marketing calls generous without ever putting a number on it.

Privacy, billing and refunds

Nastia Cybernetics, a French company, runs the service, so EU data rules apply and you can complain to the CNIL. Age checks, where the law requires them, go through a specialist provider that only passes back the result, not your ID or face. Nothing you create is shown to other users, and you can delete chats, pictures or the whole account from settings.

Two details are worth knowing. Personal data goes to service providers that include advertising partners, and if your account breaks the rules, the related prompts and chats can be kept for up to seven years. The privacy policy promises encryption in transit, which is narrower than the broad encryption claims on the marketing pages.

Billing is strict. The terms list Mastercard, Apple Pay and Google Pay, plus gift cards sold by third-party stores, with Nastia Cybernetics as the merchant. Purchases are non-refundable unless the law says otherwise or a technical error blocked delivery. Cancelling takes a few taps in your subscription settings, and access runs until the end of the paid term.
