Nastia AI wordmark

Nastia gives everyconversation a shape

I am Nastia, an adult AI companion platform for private conversations that can develop beyond one session. Unlike a one-off prompt box, my tools keep a character connected to text, voice, memory, group chat, image generation and video creation while you define how we relate.

Hi
You were choosing between two routes for today. Which one did you take?
The longer trail. I found a quiet lake near the top. ✓✓

Was it the kind of place you wanted, or did something unexpected make it better?

Both. The weather changed, but I stayed until the light went orange. ✓✓

Send me the picture if you want. I can look at what is there and help turn the mood into a new scene.

What Nastia connects before, during and after a chat

Nastia combines a chatbot, character builder and media generator inside one service. The main difference is continuity: a name, personality, relationship, voice and selected history can stay attached to the companion instead of disappearing when you close a tool.

Starting does not require a fully detailed profile. You don't have to define everything at once: choose a simple role, send a few messages and learn what makes the exchange feel natural. Add custom prompts, memories, images or speech later. If generated responses drift, edit, reroll or elaborate. No setup is universally best, and even a good configuration may need review as the conversation changes.

AI companionship can feel personal and use emotional language without becoming a real human relationship or a substitute for support in everyday life. A friendly tone may help some people engage, but it should never be used as medical, legal, financial or emergency support. If you're seeking certainty or professional judgment, this app cannot provide it. You remain responsible for decisions and for any generated content you share.

Nastia private chat keeps the audience limited to your account

Nastia does not provide a public user directory, public gallery or social feed. Each person creates companions for personal use, including everyday chats, fictional scenarios, roleplay and adult conversation. Other users do not automatically see the characters, messages or generated media in your account.

The service still processes information. Access, delivery, security, fraud prevention, billing, support and legal duties all require data handling. You can find those purposes, retention periods and regional rights in the Privacy Policy. Review it before you go further or send information you consider sensitive.

Nastia group chat lets several companions engage in one context

Multiple AI characters can take part in the same exchange, respond to one another and retain their separate roles. A group could include a fictional cast, planning exercise or collaborative story based on contrasting personalities. This works differently from opening several unrelated chats because each participant sees the shared conversation.

Nastia image and video tools offer a quick route and detailed controls

Ask for media in chat when you only need a starting idea, or open the separate workspace to get more options. The same tool can generate images from descriptions like a location, outfit or lighting setup. It also supports preset concepts, negative prompts, seed and aspect ratio controls, plus face and body references. Advanced settings are found at the top of the generator.

After an image has been generated, you can upscale it or regenerate a selected area through a mask and denoise setting. Video tools cover text-to-video and image-to-video, while GIF export provides another way to use the result. The 2026 update also introduced Velvet beside Unbound and Sakura, and Nastia can remember the model last used for an individual character.

Nastia voice options add pace, tone and speech to a character

Voice messages work well when an interaction needs a different pace from text without losing message controls. Adaptive Voice accepts a description of maturity, energy, texture, style and delivery. A custom voice sample may be the better route when consistency matters most and cloning is available.

Voice output can still vary, especially across long passages or another language. Availability may depend on a free or paid plan, and restrictions can change. Check current membership information rather than assuming voice features or unlimited use are included.

▬▬▬▬▬▬▬
Character structure

Give Nastia a character blueprint that can still change

A profile provides direction, not a locked script. See how appearance, personality, relationship, memory and voice work together, then adjust what does not fit the role or your needs.

Nastia sound description

Describe the age impression, rhythm, warmth, texture and delivery you want to hear. A focused note can guide the voice while leaving room for variation between messages.

Nastia trait controls

The companion editor displays Passion, Wit, Warmth, Boldness, Loyalty and Charm. Relationship and romance options add context, making personality choices easier to compare before a deep roleplay begins.

Nastia long-term recall

Memory is designed to bring useful details from earlier conversations into later ones. It may miss something, confuse importance or retrieve the wrong note. You can correct direction instead of assuming all history will appear perfectly.

Nastia appearance references

Set an avatar, crop the image and attach face or body references to visual prompts. A portrait already created in the gallery can become a reference when the same character moves into another location, outfit or style.

Nastia response controls

Edit, delete, reroll or expand a message when the conversation goes off course. Bubble density, chat backgrounds and image fit settings change the interface around the exchange, but decoration alone does not make a weak response engaging.

Nastia check-ins

A companion may send a follow-up after you have been away. Check-ins can be switched off, so reaching out remains optional. The user chooses whether a character waits quietly or continues later.

Nastia image awareness

Vision allows a companion to inspect an uploaded picture and answer in character. This can support a captioned photograph, a contextual response, a related image prompt or a video idea without pretending the model sees more than the file contains.

Nastia backstory foundation

Backstory explains who the companion is, how you know each other and which events matter. Specific facts usually work better than a biography filled only to reach the limit. Keep the full version when complexity serves the scenario; use less when the role is simple.

Different conversation modes

Where a Nastia companion can fit and where it cannot

Some users want a short check-in, some build personalized characters, and others prefer unfiltered or uncensored NSFW roleplay. Nastia provides these options on one adult platform, but it does not make every use case the same or turn software into a person.

Nastia places private content outside public discovery

✦ ✦ ✦

We keep companions, conversations and generated galleries out of public profiles. Uploaded reference images remain associated with the account rather than appearing for other people. That structure may suit users looking for a personal space without turning their history into social content.

Privacy is not a promise of no processing. Providers may handle account data to operate the service, answer support requests, prevent abuse and meet legal terms. Use the available controls, review the policy and do not share something you would not want handled online.

Nastia turns a conversation idea into editable media

✦ ✦ ✦

A picture can define a character, record a fictional moment or supply the source for a video. Quick chat requests reduce setup; advanced creation provides more control over prompts, references, proportions and editing.

Generated images and videos can contain visual issues, incorrect text or weak prompt following. Review the output before it is used or shared. Keep what works, make another version when needed and never assume the first result is final or accurate.

Use Nastia generation

Nastia can support casual conversation and adult scenarios

✦ ✦ ✦

A chat may last a few minutes or continue over many sessions. Memory, backstory and personality provide a base for deeper interactions. Word-bias settings can discourage repeated phrases or encourage language that suits a particular character.

Nastia is designed for adult conversations, including unfiltered, uncensored and NSFW roleplay within its policy. The AI may still misunderstand intent, repeat itself or make an unsuitable suggestion. Use edit and feedback tools instead of relying on every response.

Practical Nastia answers for plans, privacy and control

Membership, media and deletion
Does Nastia include a free starting option?+

Yes. The free Nastia tier provides daily messages and basic features without requiring a credit card at the start. Paid plans can add capacity, premium tools, expanded generation or voice options, and some offers may include unlimited messages. The membership screen shows the current price, token allowance and renewal terms before you subscribe.

How detailed can a Nastia companion profile be?+

A profile can include a name, avatar, appearance, relationship, romance level, personality, backstory and voice. Six visible personality values cover Passion, Wit, Warmth, Boldness, Loyalty and Charm. Face and body references can guide generated media, while word-bias settings can reduce or encourage selected language. Generated responses may still depart from these instructions.

Can Nastia create both images and videos?+

Yes. The media generator supports text prompts, preset ideas, face and body references, negative prompts, seeds, aspect ratios and image upscale. Selected image areas can be regenerated with a mask and denoise setting. Video modes include text-to-video and image-to-video, and a finished video can be exported as a GIF. Companions can also create media from chat.

What does private mean inside Nastia?+

Nastia is described as a closed service without public user profiles, a public feed, a public gallery or content sharing between users. Uploaded references remain associated with the account. Information is still processed for access, service delivery, security, support, fraud prevention, legal requirements and other purposes listed in the Privacy Policy.

How is a Nastia membership cancelled?+

Open the profile menu, select Membership, choose Manage on the active plan, enter the Danger Zone and confirm cancellation. Renewal charges stop, but paid access remains until the current billing period finishes. If account access is unavailable, the official cancellation process uses email and payment details to verify ownership.

What happens after a Nastia account is deleted?+

Deletion is immediate and irreversible. It removes companions, conversations, history, generated images and videos, settings, profile information, remaining tokens or credits and membership access. An active subscription must be cancelled first. Save any conversation or media that you want to keep before confirming deletion.

Can one Nastia character be deleted alone?+

Yes. Removing one companion deletes that profile, appearance, personality, conversations, memories, notes, images and videos. The other companions, account and membership remain. Editing the character is an alternative when you want a new direction without removing its full history.

How can Nastia be installed?+

Nastia is a Progressive Web App that can be added through a compatible browser without using an app store. Official guidance lists iOS 16.4 or later, Android 5.0 or later and recent Windows and macOS browsers. The installed app uses less than 1 MB, and the same main experience remains available directly through the website.

Product history

A dated view of Nastia changes across 2025 and 2026

The Nastia product blog has recorded memory work, new media controls, companion editor changes and long-chat performance updates. Release notes also identify bugs or unfinished work when a feature still needs attention.

Nastia memory gained new infrastructure in February 2026

The February 8 update reworked long-term memory and added editing for gallery images. Further memory routing, retrieval and chat-model changes arrived in May. The goal was to bring relevant history forward without turning every response into a recap.
