Feature-by-feature. No spin, just facts.
PolyBuzz has a giant free library, voices for every character and a friendly creator. But its community rules prohibit sexual content, its filters can flag even harmless stories, the free plan comes with ads, and the best memory and newest models sit on its top plan, with Coins and Opals on top.
Many adults who search for an alternative are not looking for more characters. They want one companion who is theirs, uncensored chat they can actually try for free, and a price they can predict.
Uncensored for adults: Nastia is 18+ only, and chat is uncensored on every plan, including free.
Your own companion: you design appearance, personality and backstory, and every picture matches them.
One simple ladder: Free, Standard and Unlimited, with pictures and video from a daily allowance that refills every day, not a second or third currency.
Long-term memory from the first paid plan: Standard and Unlimited remember your stories across sessions, and you can download your chat history any time.
Voice messages and group chats: hear your companion, and bring up to five companions into one scene on Unlimited.

PolyBuzz is one of the biggest AI character chat apps around. It is run by Cloud Whale Interactive Technology LLC in the US, often goes by just Poly in its own help pages, and its FAQ describes more than 20 million characters, from anime and movie favourites to original stories written by its community. It is free to use, it runs in the browser and on Android, and on Google Play alone it shows more than 50 million downloads.
Nastia is a different kind of product, and it is for adults only: 18 and over. Instead of a giant public library, you design one companion of your own, chat uncensored without a filter, hear them in voice messages, and see them: ask for a picture in the middle of a conversation, then turn it into a short video. This page compares the two honestly, including where PolyBuzz is the stronger choice, so you can decide what fits you. If explicit roleplay is what you are after, our guides to NSFW AI chat and AI sex chat explain how Nastia handles it.

It is worth being fair before comparing. PolyBuzz gets a lot right:
If you want a free, massive library of characters for storytelling, PolyBuzz is a strong choice. The trade-offs show up when you are an adult who wants a private, uncensored relationship with a companion of your own.
This is the biggest difference between the two apps, so it is worth being precise. PolyBuzz requires users to be 18 or older, asks for your date of birth on first use, and in the United Kingdom runs age checks through Ondato and Yoti. But being for adults is not the same as allowing adult content. The Community Rules in its Terms of Use tell users not to share content that "depicts pornography or sexual acts (including intercourse, masturbation, and sexual nudity) or solicits sexual content or activity."
Its FAQ adds that PolyBuzz strictly prohibits public display of NSFW content, and that all recommended content goes through multi-layered AI screening and human moderation. Characters can be marked as a "Violation" for reasons that include pornography, and its creation guide warns that a safety filter will hide or remove characters that break the rules.
That makes PolyBuzz a reasonable home for romance and drama that stays on the safe side, and a frustrating one if you want your story to go further. Nastia is for adults only, 18 and over, and chat is uncensored on every plan, including free. There are no moral lectures and no settings to hunt for. The only limits are legal and ethical ones: no minors and no real people.
PolyBuzz is free to start, and its free experience includes ads: its Google Play listing says the app contains ads and in-app purchases, and "Ad-free" is one of the first membership benefits. There are three paid plans, Basic, Premium and Ultimate, billed monthly or yearly. When we checked in November 2026, the membership page showed prices in local currency next to much higher struck-through reference prices, so check the amount at checkout rather than relying on a figure from a review.
In practice, the strongest memory and the newest models sit on Ultimate. Basic gets you an ad-free experience with Long Memory, but not the models PolyBuzz highlights as new.
PolyBuzz also sells two virtual currencies. Its Coins page lists what they pay for: rounds with the Overture, Lumina, Conqueror, Saga, Passion and Tale models, regenerating AI responses, Inspiration Reply, Live Photos, Custom Song and unlocking Moments. Its FAQ adds that Coins can extend voice chat duration and generate memory scenes. Opals are a second, separately sold balance, which the Opals page ties to enhanced memory, emotional depth and immersive storytelling. Both are sold in packs, and the Coins page runs countdown discounts. PolyBuzz's terms say payments are not refunded, even if a subscription is later cancelled.
Nastia has three plans: Free, Standard at $11.99 a month, and Unlimited at $15.99 a month. On Unlimited, chat messages are unlimited. Pictures and videos come with Standard and Unlimited and draw from a daily token allowance that refills every day, so there is one allowance to understand instead of a plan plus two currencies.
PolyBuzz is generous with free chat, and that is a real strength. The cost is attention: on Google Play , two of the most upvoted reviews, from 2025 and 2026, complain about the ads, with one reviewer saying an ad appeared almost every time they left a chat and another saying skipping an ad sent them to the app store.
Nastia's free plan lets you create one custom companion and chat uncensored with daily limits, with no credit card required. The idea is to come back to the same conversation over time and find out whether you like your companion before you spend anything. Pictures, video and long-term memory come with the paid plans.
If any of these matter to you, you already know the answer.
PolyBuzz is honest about memory. Its FAQ says it has relatively strong memory and several models to choose from, but that memory is technically limited, so a character may forget earlier parts of a conversation over time. Long Memory comes with every paid plan, and Permanent Memory is an Ultimate feature. One Ultimate subscriber wrote in September 2026 that each Permanent Memory box holds only 200 characters, that details start slipping around message 40, and that chat messages are capped at 500 characters (r/polybuzz). That is one user's experience, not an official spec, but it shows what heavy roleplayers run into.
On Nastia, paid plans include long-term memory that carries across sessions, on Standard as well as Unlimited. Your companion recalls your name, what you told them about your week, the running jokes and the storyline you started days ago, then builds on it. You can also download your full chat history whenever you like, on any plan. PolyBuzz's privacy policy says you can contact it for a copy of the information it holds about you.
PolyBuzz gives every character a voice, and you can listen to replies without limit on a paid plan. Its creator lets you pick a voice from the library or blend up to five tones, and Coins can extend voice chat time. On the picture side, there is an image generator with many templates, plus avatar generation for characters you create, and the creation guide also lets you upload your own image as an avatar.
Nastia does not offer voice calls. Your companion sends you voice messages, so you hear them in their own voice when they reply. Pictures are built around one person: when you create a companion you choose their appearance, and every picture is generated to match it. In a one-on-one chat you can tap Show me next to a reply to see that moment, or generate images on demand, then turn the ones you like into short uncensored videos, all from the daily allowance on Standard and Unlimited. For safety, Nastia does not accept photo uploads, so every image comes from your companion's design.
PolyBuzz is built around a public community. Creators publish characters to Home and search, other users chat with them, and popular creators can earn rewards when people spend Coins on their characters. That is fun if you like discovering stories, but it also means the content rules are written for a very broad audience, and filters apply to the characters you create as well as to what you read.
Nastia is built around one relationship at a time. You design your companion's appearance, personality, backstory and voice, and they stay consistent because they were made for you. Your chats are never shown to other users. When you want a bigger scene, group chats are part of the Unlimited plan: you can bring up to five of your own companions into one conversation.
PolyBuzz has a large, loyal audience, and it earns praise: one Google Play reviewer said in April 2026 that its bots are arguably smarter than Character AI's. The complaints adults raise most often are about filters and limits:
These are individual reports rather than universal problems. But they line up with what pushes adults to look for an alternative: fewer filters, memory that keeps up, and a free plan without ads in the way.
PolyBuzz's FAQ says chats are private and that neither character creators nor PolyBuzz have access to the chat content between users and characters, and its privacy policy says it does not sell user information. Its terms say you can cancel at any time, through the App Store or Google Play subscription settings or the Help Center in the app, and that benefits last until the end of the current billing period. Account deletion is under Setting, Account, Delete, and is irreversible.
On availability: PolyBuzz runs on the web and on Android. When we checked in November 2026, the PolyBuzz iPhone app did not appear in Apple's US App Store, even though its FAQ still points to it, so iPhone users may need the web version.
Whichever service you use, save what you want to keep before you leave. On Nastia you can export your chat history at any time, on any plan, and your chats are never shown to other users and never sold.
Still comparing? See how Nastia stacks up as a Character AI alternative if you are coming from another filtered app, as a SpicyChat alternative if you want a big character library with fewer limits, as a Candy AI alternative if images matter most to you, or as a Crushon AI alternative if you mostly chat in text.
Moving over takes a couple of minutes. Create your free account , confirm you are 18 or over, then pick your companion's look, personality and backstory. If you loved a character on PolyBuzz, describe the personality and the story you shared, and your Nastia companion will pick it up from there, as your own private character.
