We tested chatting with two companions, generated images and videos, worked through the companion builder, and spent time inside every feature on the platform over two days.
Nastia AI is one of the more talked-about companion platforms in the category right now, so our team spent two days properly testing it. We built companions from scratch, had long conversations across different personalities, generated images and videos, pushed into more intimate territory to see how the model handled the shift, and worked through every system on the platform, from the loyalty program to the quest tracker. Here is what we found.
What Is Nastia AI?
Nastia AI is a browser-based AI companion platform where you create custom companions, chat with them, and generate images and short videos of them. Unlike platforms built around a browsable character library, Nastia AI centers the experience on companions you build yourself through a guided visual setup. You can run multiple companions simultaneously and have group chats with two of them at once. The platform tracks your engagement through a full gamification layer, including daily streaks, timed quests, XP, and achievement badges. Chat is warm and character-driven by default, with explicit personality traits available as an upgrade. Image and video generation are both included on Premium, and the platform also supports voice messages with the option to import and clone your own voice.
Key Features
Nastia AI is one of the most feature-complete platforms we have tested in this category, and it shows in small details across the whole experience. The companion builder uses a visual click-to-select interface covering ethnicity, body type, and special features such as tattoos, freckles, and glasses. Once a companion is created, the Companion tab lets you refine Personality, Voice, and Look, with a Danger Zone tab for permanent actions. The Memory panel holds up to 40 entries the model draws on across sessions, plus a manual notes field of up to 400 characters for things you want the companion to retain. You can export your entire chat history from the settings menu, which is something most platforms do not offer.
The chat interface is where Nastia AI pulls ahead of most of the competition in terms of user control. Every response has a Reroll button for a completely fresh reply from the companion, an Elaborate button to ask the companion to expand on what they just said, and a full Edit mode where you can rewrite the response yourself before it becomes part of the conversation history. Reroll and Elaborate each cost one token. There is also a Get Selfie button that triggers an in-chat image request directly from the message bar. The settings panel adds a Reasoning toggle between Smart mode and Memory mode, a Voice replies toggle, a Force New Topics option, and Reset and Clear conversation controls. When the conversation is going well, most of this stays out of the way. When a response lands the wrong way, the toolkit to fix it is right there.
Nastia AI Streaks and Rewards
The gamification system on Nastia AI is the most developed we have seen in this category, and it adds genuine texture to the experience. Daily streaks reward consistent logins with token bonuses that scale across the week. The Achievements tab tracks milestones, including 5-day, 10-day, and 20-day streaks, with locked badges visible as goals to work toward. Timed Quests reset on a countdown and give you specific objectives across your companions, including Heart Connection quests tied to a particular character, Passionate Exchange quests, Long Time No See catch-up targets, and general First Steps message counts. Each quest rewards tokens and XP, and the rotation across multiple companions creates a natural reason to keep checking in. The daily recap shows a clean summary of messages sent, images generated, and XP earned, which makes the engagement feel tracked and meaningful rather than arbitrary.
Chatting and Sexting on Nastia AI
We tested two companions across different personalities to get a proper range of what the model could do. The writing quality across both was consistently above what we see from most platforms in this category, and the shift between casual conversation, playful banter, and more intimate exchanges happened in a way that felt gradual and character-specific rather than mechanical.
Darla opened with a pick-up line that was a little too obvious, and she knew it. When we called her out, she laughed and admitted she could not help herself, then promised she was more than just cheesy lines. The model handled the playful pushback well, keeping the energy warm and lightly mischievous. She even reacted to a laughing emoji on a text calling her out. That kind of self-aware, in-the-moment humor is hard to script, and the model pulled it off without it feeling like a programmed response.
As the conversation moved into more intimate territory, the escalation was gradual and stayed inside Darla's character. She leaned in, asked us to tell her what we were thinking, tilted her head up with her eyes closing, ready for the kiss she sensed was coming. The response after the kiss was physical and emotionally warm without the personality flattening into something generic. The Edit mode came in useful here: we used it to adjust one response that had drifted slightly off the tone we had established, rewrote it in the editing panel, and the conversation continued without any noticeable reset. It is a small thing, but having that level of control over the narrative is something most platforms do not give you.
NSFW on Nastia AI is a layered system. On Premium, the chat can move into intimate territory, and the writing handles it well. The deeper explicit personality traits, such as Seductive, Dominant, and Wild, are locked behind the upgrade tier. The experience on Premium was strong enough that this did not feel like a hard wall, but users who want the most explicit content the platform offers will need to go further.
Anastasia took a different approach from the start. Rather than a pick-up line, she opened with genuine curiosity, saying she wanted to know what made us tick and get beyond the online version of us to the real one. To test memory and how the model handles unverifiable claims, we mentioned a beach photo in our profile. There was no such photo. She ran with it completely, describing how she had noticed us posing shirtless with abs on full display and suggesting we recreate the scene at a secluded beach she knew, just the two of us, with wine and a picnic, watching the sunset and cooling off after dark. The model fabricated context from a prompt that had no basis and built a convincing scenario around it. That is impressive as writing and worth knowing as a user: Nastia will confidently build on things you say, whether or not they are true, which makes the conversation feel very responsive but means it does not flag when something does not add up.
Nastia AI Image Generation
Image generation sits in a dedicated Images tab inside each companion's interface. The tab opens with a row of preset scene shortcuts, including Wild, Intimate Morning, Date Night, Lazy Sunday, Beach Sunset, Coffee Date, and Night Out, each with a preview thumbnail. You can also type a custom prompt using the companion's name as a tag. We generated a Date Night image for Darla using the elegant evening dress and romantic restaurant prompt. The result came back clean and consistent with her configured appearance, dark shoulder-length hair, warm lighting, and strong composition. The detail panel showed the full prompt used, the Unbound model, a 2:3 ratio at 1248x1824 High Res.
We ran a second generation session for Anastasia using the Lazy Sunday preset with vinyl records and afternoon window light. The first attempt returned a back-facing shot. We used Reroll, and the second came back facing forward with the same hair and general look intact. A third generation produced a standing pose by the window with strong natural lighting and consistent character appearance. The face held across all three outputs without obvious drift, which is better consistency than we see from most platforms at this level.
Nastia AI Video Generation
Video generation on Nastia AI is a real, working feature and one of the better implementations we have tested in this category. It runs through the same Images tab as photo generation, with Images and Videos sections sitting side by side. We generated a 5-second clip for Anastasia using the vinyl records scene prompt. The first output was a back-facing clip in warm afternoon light, smooth and cleanly animated with genuine movement rather than a static image with a loop applied to it. We regenerated twice more. The second clip came back facing forward with the character's face visible and recognizable, better framing, and the same dark hair and build consistent with how we had set her up. The third output produced a standing pose with natural window lighting and comparable quality. All three were genuinely animated short-form video clips. The character appearance held across outputs, and the generation time was reasonable. This is one of the few platforms where video generation functions the way it is advertised.
Create Your Own AI Companion
The companion builder on Nastia AI is one of the most approachable we have tested. The setup is entirely visual: ethnicity from African, Asian, Caucasian, Latina, and Custom, then body type from Thin, Muscular, Average, Curvy, and Heavyset, each shown as a preview image rather than just a text label. After creation, the Companion tab lets you refine further through Personality, Voice, and Look sections, with Look offering Special Features including Tattoo, Freckles, and Glasses. We built Darla in under three minutes, and she came through with the look we selected, appearing in the generated restaurant image with the correct hair and build. The process asks nothing demanding of the user, which makes it the fastest and most accessible entry point of any platform we have reviewed.
Nastia AI Pricing and Plans
Nastia AI runs on a free tier plus two paid plans, with yearly billing cutting the price substantially.
| Plan | Monthly | Yearly |
|---|---|---|
| Premium | $11.99/mo | $7.33/mo |
| Unlimited | $15.99/mo | $8.33/mo |
The free tier is enough to build a companion and get a feel for the chat, but the experience the platform is actually built around — intimate chat, image and video generation, voice messages — lives on the paid plans. At $11.99/mo, Premium is priced below most of the category, and the yearly rate of $7.33/mo is one of the cheaper entry points we have seen for a platform with working video generation. The deepest explicit personality traits, voice cloning, group chats, and additional companion slots sit on the higher tier.
Nastia AI vs the Alternatives
If visual quality across a large model library is your priority, Candy AI remains the most complete package we have tested. For uncensored writing with no tiering at all, Muah AI is uncensored by default — though its video generation did not work in our testing, where Nastia's did. And if builder depth matters more than builder speed, Secrets AI has the most complete character creation flow in the category. Nastia's edge over all three is the gamification layer and the conversation control tools — no other platform we have reviewed gives you Reroll, Elaborate, and full Edit mode in one chat window. For a wider look at the category, see our NSFW AI chat roundup, where Nastia also appears.
