Nastia

What Nastia is

Nastia is an uncensored AI companion service for adults. Users create a companion, chat with it in text, and receive pictures and voice messages in return, and the site presents explicit chat and erotic roleplay as part of the normal product on every plan. There is a free plan that the site describes as free forever, with no credit card, no trial and no expiration. The free plan covers one companion. The site is run through a web sign-up that its About page says takes less than 20 seconds. The NSFW chat page says no download is needed, that Nastia works in a browser on any device, and that it can be installed on a phone as a progressive web app with push notifications, a route the site says it chose to stay outside the app stores.

The company behind it is Nastia Cybernetics, and the content policy describes it as a France-based company. At its core the About page describes a large language model, and says each chat is free of pre-scripted content. That makes Nastia useful both as a girlfriend or boyfriend style companion and as a roleplay engine, which the sections below separate.

What you can do with it

A session starts with a companion. The nsfw chat page says customization covers appearance, personality, voice, name, backstory and behavior, and gives submissive, dominant, playful and teasing as examples of personality. The roleplay page lists full character customization and says you can build a partner from scratch, whether that is an AI girlfriend or an AI boyfriend. The same page says her personality stays consistent across every conversation. A separate character chat page says the site hosts 98+ characters, each with persistent memory, a set personality and NSFW switched on, and that you can also create your own. Those characters are drawn from anime and similar fiction, and the NSFW chat page says you can even chat with anime and hentai AI characters.

Roleplay is a main use. The site describes group chats, where several AI companions interact in one session and build on each other's dialogue. It describes uncensored roleplay that includes romantic, intimate and explicit scenes, with no lectures and no fade-to-black. The About page lists other uses too, such as emotional support, reflection and mindfulness, goal setting, and writing and creativity. Those are worded as secondary to the companion role, but a reader who wants a mix of conversation and roleplay will find them listed.

Memory is stated plainly. The roleplay page says Nastia has persistent memory that carries across conversations, including characters, plot points, shared lore and inside jokes. The sex chat page says a companion remembers your kinks, preferences, favorite scenarios and the details of your dynamic, so you do not re-explain them each session. The site does not publish how much context it holds.

Images arrive in the conversation. The site says a companion generates and sends pictures during chat, described as selfies, boudoir and explicit content, and it links a separate NSFW image generator. The About page describes uncensored AI images as part of the companion experience. Video is also listed: the roleplay page mentions an uncensored AI video generator that turns a scene into a clip, and the sex chat page lists AI video among the things a paid plan adds. The plan list puts selfies at 4K and video generation at 1080p on the paid plan.

Voice is part of the product. The sex chat page says a companion sends voice messages and responds to intimate messages in audio, and it says this is available on all plans. Another page lists voice among the upgrades from the free plan, and the plan list places voice messages under the paid plan, so the site words it two ways.

The sex chat page is the clearest description of the NSFW chat itself. It says Nastia engages in explicit dirty talk, describes intimate scenarios in detail, responds to fantasies and escalates naturally, with no topic switching and no moralizing. The site says uncensored chat stays on every plan.

Free tier, plans and billing

The durable facts come first. There are 2 tiers, Free and Unlimited. The free plan includes uncensored chat with one companion, covering dirty talk, sexting and intimate conversation, and the plan list describes it as chat with daily token limits and basic companion customization. Upgrading adds unlimited messages with no caps, voice messages, NSFW images, AI video and multiple companions, according to the sex chat and NSFW chat pages. The paid plan is priced per month, and the terms say a recurring charge continues until the subscription is canceled.

In October 2026 the plan list on the NSFW chat page shows Free at $0 and Unlimited at $15.99 a month.

Cancellation is documented. The help center says you can cancel anytime from the membership page, by opening the sidebar, the settings sheet, Membership, Manage, Danger Zone and then Cancel membership. The membership stays active until the end of the paid period and does not renew, and you will not be charged again. You can resubscribe by clicking Renew. The cancel flow asks optionally why you are leaving, and the page says an offer or a pause may be suggested if you answer. The terms say payments are in US dollars and that prices can change at any time. On refunds, the terms say purchases are non-refundable unless the law requires otherwise or a technical error occurred, and they point to a separate refund policy. The cancellation guide also explains how to recover a lost account, which requires the last 4 digits of the payment card and details of the most recent charge.

Deleting an account is separate. The account deletion guide says deletion is permanent and irreversible, removes companions, images, videos, conversations and settings except limited records described in the privacy policy, and requires canceling an active subscription first.

Rules and privacy

The terms say Nastia is for users who are at least 18. The content policy says content that sexualizes minors is strictly prohibited, that automated safeguards backed by human review run at the point of generation, and that confirmed cases lead to account termination and a report to the authorities. The same page describes Nastia as a closed, private service with no public feed, profiles or galleries, and says reports from anyone are acted on, with illegal content removed immediately once it is identified. The terms prohibit content that depicts or impersonates a real, identifiable person, including public figures, and they are governed by French law. A compliance statement says all generated images and videos are computer-generated and that no human performers appear.

On privacy, the homepage says conversations are protected with industry-standard encryption, are not sold or shown to other users, and are shared only with service providers described in the privacy policy. Conversations can be deleted at any time.

Who it suits

Nastia suits someone who wants a long-running companion with memory, explicit chat on every plan, and the option to add voice, images and video later. It also suits a roleplay writer who likes group scenes with several companions and a library of ready-made characters. The free plan with one companion is enough to judge the chat quality without a card.

The caveats are specific. The free plan covers one companion and runs on daily token limits, and the site does not say how many messages those limits allow. There is a single paid tier, so a reader cannot pick a cheaper step between free and Unlimited. Purchases are non-refundable under the terms outside legal requirements and technical errors. Voice is worded differently from page to page, and deleting an account means canceling the subscription first.
