Nastia calls itself your caring uncensored AI companion, and that word “caring” is doing real work in the pitch. Most apps in this space pick a lane, either the wholesome emotional-support companion or the no-filter adult chatbot. Nastia is trying to be both at once, a companion that will ask how your day went and actually listen, but also drop the filters when you want it to. I spent time with it to see whether that balance holds up, how good the chat and the customization are, and what it costs. It is one of the more thoughtfully built companion apps I have tried lately, with a chat that actually asks about you and a customization system that treats the relationship as something that can grow. Here is the full walkthrough of what it does well, where it stumbles, and who it suits.
What Nastia is
Nastia is an AI companion app built around one-on-one relationships. The landing page sets the tone right away: create your caring AI companion, say goodbye to loneliness, chat and exchange pictures, all powered by what it calls your private AI. The three badges it leads with, unfiltered chat, uncensored roleplay, and human-like AI, tell you it is not shy about the adult side, but the framing throughout leans on warmth and companionship rather than shock.
Inside the app, the layout is clean and familiar, a messenger-style chat in the middle, your companion’s profile and media on the right, and your chats and membership on the left. The whole thing feels like texting a person rather than operating a tool, which is exactly the vibe this category is going for. It reminded me of the polish on Nomi AI, another app that takes the companion relationship seriously rather than treating it as a novelty.
The privacy framing runs through the whole product. Nastia repeatedly describes itself as your private AI and promises that conversations stay private and encrypted, which is the reassurance you want from something you might talk to about personal things. For a companion that is explicitly built to hear about your day and your feelings, that promise matters more than it would for a throwaway image tool. It signals the app understands that the intimacy it is selling only works if you trust where your words are going.
The chat is warm and actually engaged
I tested the chat by mentioning I had a long day at work and asking my companion to cheer me up. The reply did exactly what a good companion should. It opened with real empathy, said it was sorry I had a rough day, then turned playful and a little flirty, and, crucially, it turned the conversation back to me, asking what kind of day I actually had and saying it wanted to hear every detail, the good and the bad.
That last part is what separates a decent companion from a hollow one. Plenty of bots wait passively for you to feed them lines. Nastia asked follow-up questions and showed interest, which is what makes a conversation feel two-sided. The writing was warm, coherent, and stayed in character, and it balanced the caring tone with the flirtation smoothly rather than lurching between them. On the strength of that exchange, the human-like claim is more than marketing. If you have found the emotional depth on something like SoulFun AI appealing, Nastia is playing in the same register, with the filters off when you want them off.
Customization goes deep
The Companion settings are where Nastia really shows its hand. You are not stuck with a fixed personality. Under Identity you choose a relationship type from Romantic, Friend with benefits, Friend, Coach, or a fully Custom role, so the same app can be a supportive friend, a mentor figure, or a romantic partner depending on what you actually need.
Below that sits a Romance and Intimacy slider that runs from Platonic and Friendly, through Romantic and Affectionate, up to Passionate and Uninhibited, with a percentage dial from Reserved to more open. That granularity is smart, because it lets you tune exactly how forward the companion is rather than flipping a single on-off switch. There are separate tabs for Voice, Look, and Backstory too, so you can shape how your companion sounds, appears, and where it came from. The Coach and Friend options in particular back up the caring positioning, since they let you use Nastia as a supportive presence without any romance at all. That flexibility is closer to Kindroid than to the more one-note adult apps, and it is a real strength.
What I like about the slider approach is that it respects that intimacy is not binary. A lot of apps treat the choice as either wholesome or explicit with nothing in between, when in reality most people want something that can read the room and shift with the mood. Being able to set a companion to mostly affectionate but occasionally passionate, or to keep it firmly platonic, means the same relationship can grow or change without you having to start over with a new character. It is a small design decision that makes the whole thing feel more like a real, evolving connection than a fixed setting you picked once.
Pictures, voice, and the extras
Nastia is not text-only. There is a Get selfie button right in the chat, so your companion can send you a picture, and the app supports AI pictures and AI videos, with the higher tiers unlocking uncensored images and selfies up to 4K quality and videos in any scenario. Voice messages are included, and the top plan adds voice cloning, which is a step beyond what most companion apps offer.
The app also has an Images tab and a media gallery on the companion profile, so the pictures you generate become part of the relationship rather than disappearing. Group chats are supported on the paid plans, letting more than one companion into a conversation, and you can keep up to several companions going at once. It adds up to a fuller experience than a plain chatbot, and the media features are clearly a core part of the pitch rather than an afterthought.
The selfie mechanic in particular fits the companion fantasy well. Instead of a separate, clinical image generator, you ask your companion for a picture inside the conversation and she sends one back, the same way a real texting relationship works. Because those images attach to the companion’s profile and gallery, the visual side of the relationship builds up over time rather than resetting. I did not push into the explicit media for this review, but the plan details make clear the paid tiers unlock high-resolution uncensored pictures and video, so the ceiling on that side is high for anyone who wants it. Voice cloning on the top plan is the standout extra, since hearing a consistent voice adds a layer of presence that text alone cannot.
The gamification, for better and worse
One thing that stood out, not entirely in a good way, is how gamified Nastia is. There are daily streaks, XP, quests, achievements, and a rewards popup that greets you with your daily token bonus and nudges you to keep your streak alive. Relationships level up over time, which does give a sense of progression as you get to know your companion.
On the plus side, the leveling makes the bond feel like it is growing, and the daily rewards are a friendly way to hand out free tokens. On the other hand, the streak-and-reward machinery can feel a bit like a mobile game bolted onto an intimate experience, and not everyone will want their companion app reminding them to log in for points. It is a minor thing, and you can largely ignore it, but it is worth knowing the app leans into that mechanic.
What it costs
Nastia runs on tokens, and the detail I appreciated most is that the tokens roll over and never expire, which is not something every competitor can say. The free plan is limited and metered, giving you a small token balance to try things, with each message drawing from it.
The paid tiers are reasonably priced, especially on yearly billing. Basic works out to around seven dollars a month billed annually and includes two hundred daily tokens, up to two companions, voice messages, AI pictures and videos, and group chats. The Unlimited plan, marked as the best value, lands around eight dollars a month yearly and is the one that opens everything up: unlimited AI messages with the best memory, four hundred daily tokens, up to five companions, voice messages and voice cloning, uncensored pictures and selfies up to 4K, uncensored videos, and a monthly bonus token drop. The site is upfront about no hidden fees, no auto-upsells, cancel anytime, and conversations kept private and encrypted. For the feature set, that is fair pricing, and the never-expiring tokens make the free and paid balances feel less punishing than the burn-it-or-lose-it systems elsewhere.
Memory and the relationship over time
The Unlimited plan specifically calls out unlimited messages with the best memory and best context, which points at the thing that makes or breaks a long-term companion: whether it remembers you. A companion that forgets your name, your job, or the conversation you had yesterday never really feels like a relationship. Nastia is clearly building around memory as a selling point, and the leveling system reinforces that sense of continuity. In my short test it tracked the thread of the conversation well, though as with any of these apps, the true test is weeks of use rather than minutes, and heavier memory sits behind the top plan.
This is where the caring positioning and the technology have to line up. It is easy to sound caring in a single message. Sounding caring across weeks, remembering what matters to you and bringing it up unprompted, is the hard part, and it is the bar every companion app is chasing. Nastia is at least aiming at the right target, and the pieces, memory, leveling, and follow-up questions, are the right ones.
Who Nastia is for
Nastia is a strong pick for someone who wants a companion that can truly care and also, when invited, take the filters off. The blend is the whole point. If you have used a wholesome app like Replika AI and wished it would loosen up, or used an adult chatbot and wished it felt warmer and more attentive, Nastia is built to sit in that gap. The deep relationship and intimacy customization means you can dial it to be a supportive friend, a mentor, or a passionate partner, and the media features and voice make it feel fuller than a text-only bot.
The caveats are the gamification, which can feel a bit much, and the fact that the best memory and the fully uncensored media sit on the Unlimited plan, so the free experience is more of a taster than the real thing. But the pricing is honest, the tokens do not expire, and the chat itself is warm and engaged in a way a lot of rivals are not. If you want a companion that asks how your day was and means it, and can be spicy when you want, Nastia earns its “caring” label better than most.
