Nastia: private chatshaped around you

I am Nastia, an adult AI companion app where one account holds your characters, conversations, memory, voice and generated media. You decide the role, style and boundaries; I provide tools for text, images and videos without presenting an AI response as human judgment.

Hi
You mentioned a difficult rehearsal yesterday. How are you feeling about it today?
Better. I changed the opening and it finally sounds like me. ✓✓

What made the new version feel more natural: the words, the pace, or both?
Nastia · 3 minutes ago
Both. The shorter pause helped too. I want to keep that detail for next time. ✓✓

I can use it as context later. If you send a picture from the room, I can also respond to what is visible rather than guessing.

Conversation, character and media in one place

Inside Nastia: several ways to interact, one continuing context

Nastia is not only a chatbot or a standalone generator. I connect private chat with character creation, persistent memory, group scenes, speech, images and video. A thought can start as text, become a voice note, move into an image prompt and later return as part of the conversation history.

You don't need to use all features at once. Try a short exchange, learn how the character responds, then add a backstory, custom voice or visual reference when it serves a real need. If a reply misses the point, edit, reroll or elaborate instead of treating generated content as fixed. Most people get a better configuration through small changes over time, not one oversized prompt.

Companionship here describes an experience, not a claim that software has feelings. Even a friendly response may be wrong, especially when a request depends on missing context, and emotional language should never replace professional support or an emergency service. If you're looking for certainty, I cannot provide it. What I can provide is a set of adjustable tools, visible account controls and dated information about how the platform changes.

01

Nastia keeps personal chat outside a public social feed

Each user creates companions for their own account. There is no public character directory, no shared gallery and no stream where other people discover your conversations. That closed structure allows ordinary check-ins, fictional scenarios, deep roleplay and adult topics to stay separate from public performance.

Private does not mean invisible processing. Account information and content may be handled for access, service delivery, security, fraud prevention, support and legal obligations, including the other purposes described in the privacy policy. You can find the relevant rights and retention details there before you share something sensitive.

Nastia lets one scene include multiple AI characters

A group chat is more than several separate chats placed side by side. Companions can share the same conversation, answer one another and keep their own character settings while a scene develops. They engage from roles based on their individual profiles, which can suit a fictional cast, collaborative ideas, a game or any roleplay where multiple viewpoints matter.

03

Nastia moves image and video generation between chat and gallery

You can ask a companion for media during a conversation or open the dedicated creation tool for more control. The generator accepts text prompts, preset ideas, face and body references, negative prompts, aspect ratio and seed settings. Advanced options are found near the top of the workspace. After an image is generated, you may upscale it or edit a selected area with a mask and denoise strength.

Video options include text-to-video and image-to-video. Source dimensions can be detected when an existing picture is animated, and finished videos can be exported as GIF files. Velvet joined the Unbound and Sakura image models in the May 2026 update, while per-character model memory reduces repeated setup.

04

Nastia uses voice to change pace without changing your control

Text works well for detailed prompts; voice can make an exchange feel less formal. Nastia supports voice messages and character voice options. Adaptive Voice allows a description of maturity, tone, texture, style and delivery instead of forcing every user through the same preset list.

Voice design and cloning are different tools. A described voice is flexible, while a clean sample may provide better consistency when cloning is available. Results can vary, language recognition is not flawless, and plan restrictions may apply. Check current membership information before assuming a feature is included.

Set the rules of a Nastia character before the first message

Unlike a fixed template, a useful character is built from specific choices. There is no single best formula: see how appearance, personality, memory, relationship and voice work together, then change the parts that pull in another direction.

Nastia voice brief

Write how the character should sound: age impression, warmth, rhythm, texture and delivery. A good brief gives the speech model a target without pretending that every note will be reproduced in exactly the same way.

Nastia personality map

Six visible axes cover Passion, Wit, Warmth, Boldness, Loyalty and Charm. Adjusting those values, the romance setting and relationship type makes an abstract personality easier to review before a long conversation begins.

Nastia memory layer

Long-term memory is designed to retrieve relevant history across sessions. It does not guarantee full recall of every message. You can still correct the character, reset direction or begin again if the stored context no longer matches your needs.

Self-discovery profile icon

Nastia visual profile

Choose a look, crop an avatar and use face or body references during generation. A created portrait can supply a face reference from the gallery, which helps when the same character appears in a new outfit, location or image style.

Nastia message controls

Edit, reroll, elaborate or delete a response when it sends the conversation the wrong way. Compact, Cozy and Comfortable density options change how messages appear, while background fit and rotation settings alter the room around them.

Nastia optional check-ins

A companion may reach out after you step away from a conversation. Check-ins can be turned off, so proactive messages remain an option rather than a requirement. You choose whether the character waits or follows up.

Nastia visual understanding

Send an image with a caption and a companion can respond to what it sees in character. Vision was integrated more deeply into chat in May 2026, supporting contextual responses, related image ideas and a smoother path from a picture to a video concept.

Nastia backstory notes

A backstory records who the companion is, who you are to each other and what has already happened. Use concrete details that affect behavior instead of filling every available line. A shorter note can be more useful than a full biography when the role is simple.

Ways to use the space

Choose how a Nastia conversation should unfold

Some users want a brief daily exchange; others create custom characters, personalized stories or uncensored adult scenarios. These are different needs. Nastia provides one platform for them without suggesting that every interaction should become emotional companionship.

Nastia separates private creation from public sharing

✦ ✦ ✦

We do not publish your companion, generated gallery or chat history as a profile for other users. Uploaded references are associated with the account rather than placed in a public collection. This makes the service suitable for people seeking a personal space, but it does not remove the need to understand data handling.

The privacy notice explains what information can be collected, why providers may process it and which regional rights may apply. Read the full policy, use account controls and do not share data you would not want processed by an online service.

Nastia gives media a place inside the story

✦ ✦ ✦

An image can record a fictional moment, define a character look or become the first frame of a short video. Use a quick request in chat when details are flexible, or move to advanced controls when prompts, references, proportions and editing matter.

Generated images and videos may contain errors. Hands, text, continuity and prompt following can still need correction. Keep the result that works, discard what does not and make another version rather than treating the first output as finished.

Nastia supports light chats and detailed adult roleplay

✦ ✦ ✦

A conversation can last five minutes or continue over many sessions. Persistent memory, a defined role, personality settings and backstory provide structure for deeper interactions. Word-bias controls can reduce phrases that feel out of character or encourage language that belongs in the scenario.

Nastia is designed for adults and allows unfiltered, uncensored and NSFW conversations within its policy. That freedom does not make every response accurate, engaging or appropriate for real-life decisions. AI can misunderstand a request, and you remain responsible for how generated content is used.

Nastia runs as a web app on the devices you already use

✦ ✦ ✦

Nastia can stay in a browser or be installed as a Progressive Web App. Official guidance lists iOS 16.4 or later, Android 5.0 or later and recent versions of Windows and macOS. The installed app uses less than 1 MB because the main processing happens on the service.

On iOS, open the website in Safari, choose Share and then Add to Home Screen. Other compatible browsers provide their own install action. If installation is unavailable, the web version remains accessible without an app-store download.

Nastia questions worth answering before you begin

Plans, privacy, media and deletion
Can I use Nastia for free before choosing a paid plan?+

Yes. Nastia has a free tier with daily messages and basic features, and you can begin without entering a credit card. Paid membership can add capacity, premium tools, voice options or expanded generation access. Some plans may include unlimited messages. Limits and prices can change, so the membership screen is the place to review the current offer before subscribing.

Which parts of a Nastia character can I change?+

You can set a name, avatar, appearance, personality, relationship, romance level, backstory and voice. The personality graph shows Passion, Wit, Warmth, Boldness, Loyalty and Charm. Face and body references help with visual continuity, while word-bias controls can discourage or encourage selected language. These settings provide direction without guaranteeing that every response will follow a prompt perfectly.

What can the Nastia image and video generator do?+

The separate media workspace accepts text prompts, preset ideas, face and body references, negative prompts, seeds and aspect ratios. You can generate an image, upscale it, edit a selected area with a mask and denoise control, create video from text, animate an existing image and export a video as a GIF. A companion may also create or offer media inside chat.

How private is a Nastia account?+

Nastia describes the service as closed: there is no public profile directory, public feed, public gallery or user-to-user content sharing. Reference images are stored privately in the account. The service still processes information for account access, delivery, support, security, fraud prevention, legal duties and other purposes explained in its Privacy Policy, so private should not be read as no data processing.

How do I stop a paid Nastia subscription?+

Open the profile menu, choose Membership, select Manage on the active plan, open the Danger Zone and confirm cancellation. Future renewal charges stop, while paid access continues until the current billing period ends. If you cannot access the account, the cancellation guide provides an email verification process.

What is removed when I delete my Nastia account?+

Account deletion is immediate and cannot be reversed. It removes companions, conversations, chat history, generated images and videos, preferences, profile information, remaining tokens or credits and membership access. An active subscription must be cancelled first. Save any conversation or media you need before confirming the action.

Can I remove one Nastia companion and keep the rest?+

Yes. Deleting one companion permanently removes that character's profile, look, personality, conversations, memories, notes, images and videos. Other companions, the account and the membership remain in place. If you only want a different direction, edit the character instead.

Does Nastia work as an installed app?+

Nastia is a Progressive Web App. It can be added from a compatible browser without an app store and can also be used directly as a website. Official guidance lists iOS 16.4 or later, Android 5.0 or later and recent Windows and macOS browsers. Installation uses less than 1 MB because processing happens on the service.

Dated product record

Nastia product changes, described without pretending issues disappear

The public Nastia product blog tracks releases, limitations and ongoing work. Four changes that have been recorded in 2025 and 2026 cover memory, media, character settings and long-chat performance.

Surreal illustrated group crossing a fantasy landscape

Nastia rebuilt long-term memory in February 2026

The February 8 release reworked the memory infrastructure and added image editing in the Photo Gallery. A later May update introduced new routing and retrieval work for memory alongside retrained chat models. The aim is relevant recall, not a promise that every past sentence will always return.

Nastia expanded media controls in May 2026

The May 13 revamp added the Velvet image model, improved masks and denoise controls, automatic face-reference setup and per-companion image-model memory. Its rebuilt video pipeline added text-to-video, improved image animation, source-dimension detection and GIF export.

Nastia made character choices easier to inspect

The revised companion editor presents creation as a sequence and displays six personality dimensions. Avatar crop supports drag and pinch zoom. Adaptive Voice accepts a written description, while chat vision lets a companion examine an image you send before it responds.

Nastia reduced the weight of very long chats

A documented performance pass reduced rendered page elements by roughly 60 to 80 percent and targeted smoother chats with more than 1,000 messages. The same release added compact token notation, three bubble-density choices, mobile composer changes and gallery-loading fixes.
