Nastia AI Review 2026: Uncensored, With Voice Messages

Nastia AI in roleplay: what the character sliders really change

The builder is the reason this app is on my list. You set the name, looks, personality, backstory, voice and a roleplay mode, and then comes the part nobody else offers like this: an extended set of sliders made up of Lust, Pride, Envy, Gluttony, Wrath and Sloth, alongside the ordinary descriptions. Independent guides describe the extended sliders as a paid feature; the free build is still detailed enough for a distinctive character.

As a game master there is only one question I have about a slider: does it change what the character does when I apply pressure? So I built my customs officer twice, with a word-for-word identical backstory, and moved only Pride. In the interrogation scenario the high-Pride version ignored my first question, parried the second with a counter-question and only negotiated after that. The low-Pride version offered to help me in the second line. The same words on the profile, two different evenings.

Where the sliders hit their limit

Two things keep the enthusiasm in check. First, the sliders act on behavior, not on format: if you write no line about the way she speaks, the replies get long no matter how the sliders are set. Second, they do not replace a concrete backstory. One paragraph with five to eight behaviors plus two deliberately set sliders is what works here, and the order I write that in is laid out at length in my guide to creating your own AI character.

On the quiet evening, my third scene, where nothing happens on purpose, Nastia AI did better than most apps with a big library: the character filled the blank with an attitude of her own instead of asking me questions about myself. That is the 8 on conversation, and it is deserved.

The roleplay mode and what it is good for

The builder additionally has a roleplay mode, and it is less spectacular than the name sounds: it shifts the tone from conversation toward scene, with more description and fewer follow-up questions. In the tavern it was useful, in the interrogation more of a hindrance, because it puts the character into a narrating posture while I wanted short, hard exchanges. So I switch it per character and not per account, and I only set it for the ones I build for scenes, not for the ones I talk to.

What Nastia AI does not have, on the other hand, is a library of ready-made characters you can borrow a role from. Everything you play you built yourself, and that is a real trade-off: it costs you twenty minutes per character, and it gives you no safety net for the evening when you just want to try something. Anyone who would rather browse than build is far better served at SpicyChat with its community library; anyone who builds has more dials here.

Nastia AI experience: the memory test after seven days

This is where the picture tips, and predictably so. The memory is a rolling context window plus a note system. The most recent messages, the backstory and everything saved as a note always stay in view; older chat slides out as new messages push in. Independent testers put the window at forty to fifty messages, and an older official comparison page still promised up to two weeks of memory, which the current page no longer claims.

My test is always the same: I drop three details on the first evening and ask about them on the seventh day. This time they were my cat’s name, my job and a dislike of meetings before nine. On day seven the job came back, the other two did not, and nothing on the screen suggested anything was missing. The chat history was sitting right there. The model simply could not see far enough back.

How to get the character to remember anyway

Dealing with it is simple, but you have to know it: treat the notes as the memory and the chat as the moment. Everything that is supposed to stay belongs in the backstory or in the saved memories, where the character reads it along with every turn. Five to ten blunt lines are enough, and they may sound as banal as a character sheet: job, town, the cat’s name, the running joke, the line that is not crossed.

Two details that make the difference. First, it helps to ask about the topic and not about the time: “What was my cat called?” works, “What did I tell you last Tuesday?” does not. Second, it pays to sort notes by scene rather than by importance, because then on the next evening you can see which backstory currently applies. I keep five lines about me, five about her and two about our shared history for every character, and in practice that is the upper limit of what I want to maintain.

Used that way, Nastia AI holds a character together well, and that is no small praise: tone, attitude and the preferences from the builder all survive. Left to the chat alone, it does not. Nomi AI builds in three memory layers and an identity core so that you do not have to do this work; here you become the archivist of your own campaign. That is exactly the distance between a 6 and a 9 on memory, and the main reason people move on after a few months.

Voice messages, images and the Nastia AI token counter

Media here are a token economy sitting on top of the subscription, and understanding that counter matters more than the price in the headline. Every plan spends tokens on images, video and voice, including Unlimited; what Unlimited lifts is the cap on text messages, and it adds a monthly token bonus. The official digital fulfillment page confirms the two purchase types, subscriptions and one-off token packs, and says that tokens are credited in real time. What no official page publishes is a list of costs per action; our platform data puts it at fifty to eighty tokens per image.

Voice messages are what the title says, and they are the part that surprised me most. You pick the voice when building the character, and on Unlimited a voice of your own can be cloned, which testers still describe as early. In the tavern the spoken line genuinely added something, because the intonation matched the character’s attitude; on longer messages it occasionally slides into the robotic. There is no real-time voice call: Nastia AI is an app for voice messages, not for phone calls.

What the Nastia AI uncensored image generator delivers

Images arrive in two ways: you ask the character for a selfie in the chat, or you open the standalone generator, where you write your own prompts, set face and body references, pick styles, upscale and work with negative prompts and aspect ratios. The generator is easier to steer than the selfies in the chat, and the results match the character’s looks well, because the reference system carries her face along. The style leans toward stylized; uploads are switched off by policy, and prompts with the names of public figures are refused. For a scene at the table that is a nice extra. As the main reason for a subscription it does not carry.

Video is image-to-video or text-to-video and only available on the paid plans. The plan card promises clips in 1080p; what arrives is a short animation of a still image, pretty for a moment and with no function in a longer scene. My conclusion after one paid month: I made exactly two videos, both in the first week, and none after that. The voice messages, by contrast, I kept using, because a spoken line changes something on a quiet evening that an image does not achieve.

Group chat at Nastia AI: several characters at one table

For me this is the feature that justifies the price. You need at least two characters of your own, you put them in a room, and they speak to you and among themselves. In my tavern the customs officer and the smuggler argued over my head for half a page, because their sliders pointed in different directions, and I actually had to intervene to pull the scene back. That is the difference between a chat and a session.

Two practical notes from the test. First, it pays to write a line into every character about how she behaves when others are talking; without that line everyone talks the same amount at the same speed. Second, the group chat needs more note work than a two-way conversation, because the context window is now filled by several characters and older material slides out faster. Anyone planning a longer campaign with a fixed cast is better off putting the shared history into every individual backstory instead of establishing it in the chat.

Third, and this is the point where Nastia AI really won me over: because all the characters are yours, you know their motives and can set them against each other. At the gaming table that is precisely the game master’s job, and no app with a big community library gives you that control, because there you are mixing other people’s cards with unknown instructions. Here I know why the smuggler cannot stand the customs officer, because I wrote it into both backstories.

Deletion is final: removing a character takes her chats, memories and media with her, and the help center documents that separately from account deletion. So do not clear space before you are sure. How the competition handles group scenes is in the comparison of the best AI character apps.

What Nastia AI really costs per month

Nastia AI pricing has one quirk: the figure on the plan card is not the figure on the statement, and that is not down to hidden items but to the way it is built. Unlimited costs $15.99 a month, or around $8.33 a month on the annual plan, advertised with about 39 percent off; a lower tier is named from $6.69 a month on the annual plan, whose monthly price only appears in the checkout and which I therefore list as not confirmed. On top of that come token packs as a one-off purchase, whose prices likewise only appear in the app.

For the three ways of using it that I know, the arithmetic looks like this. If you only write, you pay the subscription figure and nothing more, because text is not capped on the Unlimited plan; that is $15.99 or $8.33 a month, and for what the builder achieves that is a fair price. If you garnish a scene with an image or a voice message now and then, the monthly token bonus usually covers it. If you make media the main part of the evening, you buy packs on top, and then the monthly total is open-ended, because there is no published price list per action.

From that follows my advice on the order: first a free week with text only, then one paid month of Unlimited, billed monthly, and the annual plan only once two charges have gone through with no surprises. Refunds are the exception and not the rule according to the terms, cancelling in the membership area only stops future charges, and anyone who loses access is told by the help center to email the last four digits of the card, the name, the amount and the date, which tells you how manual this process is. So pay through Apple Pay or Google Pay where you can, and check on the plan card whether it says annual.

What Nastia AI stores about you

Nastia AI stores everything you build there for as long as your account is open, deletes it immediately when you delete the account, and hosts it in the US under the policy of a French company. The controller is Nastia Cybernetics, a French SAS registered in November 2023 with ten thousand euros of share capital and a business address in Saint-Laurent-du-Maroni in French Guiana. The SIREN number is in the footer of every legal page, which is more transparency than most competitors offer. At around 1,250 words the privacy policy is unusually short for this category, and I read the September 16, 2026 version in full together with the terms of service of the same date.

What is stored are your characters, chats, memories, voice messages, your own voice samples and every image and video along with the prompts and settings used. Payments run through service providers, and Nastia AI states that it never receives your full card number. Age checks, where a country requires them, are handled by a specialist provider; Nastia AI says it only receives the result, not your ID document. Retention lasts as long as the account is open, with three exceptions: payment data under tax law, records of rule violations for up to seven years, and backups that are overwritten in a cycle rather than deleted on request.

Deletion, training and the open gap

Deletion here is better than average: individual chats, images and videos can be removed at any time, an individual character along with her memories and media likewise, and account deletion takes effect with no grace period. Two catches: the account cannot be deleted while a subscription is active, so cancel first, and there is no one-click export of everything, only a download per chat. The gap that counts is model training: the policy speaks of using data to maintain and improve the service and the quality of replies, the terms grant a license to process your content, and neither document says clearly whether your chats train the model. There is no opt-out switch, and encryption is in transit and not end to end.

One last point that costs money in practice: Nastia AI is deliberately not in the app stores, so that store rules cannot cut the service down, and the installation page walks you through “Add to Home Screen” in Safari or installing from the browser on Android and on the desktop. Whatever turns up in the stores under the same name comes from unrelated developers. If an app like that charges you, Nastia AI cannot refund anything, because the money never arrived there. So install from the official site or not at all, and when in doubt check the address in the browser before you put a card on file.

My practical advice is the same as everywhere: an email address of its own, no real names in fields or notes, and cancel the subscription before you delete the account. Nastia AI treats the character you build as private; the risk is the facts you give her. Anyone coming from Character.AI who wants to see the whole field will find it at the Character.AI alternatives.
