Nastia AI Review
A budget-friendly uncensored AI companion with genuine emotional depth — but unreliable memory and broken voice features hold it back from competing with polished alternatives.
What is Nastia AI?
Nastia AI is an AI companion platform that positions itself as the uncensored alternative to filtered competitors. Launched in 2023, it lets you create customizable AI companions with adjustable personalities, backstories, and appearances, then engage in conversations without the content restrictions that platforms like Replika and Character.AI enforce. The platform runs entirely as a web-based Progressive Web App — there's no native mobile app, but you can access it from any browser and add it to your home screen.
What sets Nastia apart is the combination of its zero-filter content policy with genuinely affordable pricing. At $6.69/month for the Standard plan, it undercuts most competitors while offering group chats, image generation, and roleplay across genres from romance to horror. The emotional support features are surprisingly solid, and users consistently praise the natural conversation flow. The tradeoffs are real though: the memory system can randomly wipe weeks of conversation history, voice messaging is buggy to the point of being unusable on some accounts, and the advertised video generation feature simply doesn't work. If uncensored content at a low price is your priority and you can tolerate rough edges, Nastia is worth trying — but if you need reliability and polish, you'll find better options in our best AI boyfriend apps ranking, where the memory-first and voice-first picks hold up much better. And if it's the emotional support that drew you in and the memory wipes are the dealbreaker, My Softly is the opposite trade: an iPhone companion built specifically around remembering you, with check-ins that come to you first. There's also a broader roundup of SFW AI boyfriend options.

Who Is Nastia AI Best For?
Nastia AI is built for adults who want an AI companion without the content restrictions of mainstream platforms like [Replika](/replika/) or [Character AI](/character-ai/). If you're looking for uncensored creative roleplay, emotional support, or NSFW interactions at a budget-friendly price, Nastia delivers where competitors hold back. It's less suited for users who need reliable voice features ([Kindroid](/kindroid/) is better there), want a polished native mobile app experience, depend on long-term conversation memory ([Nomi.ai](/nomiai/) leads the category), or need support in languages other than English. If any of those are dealbreakers, our [Nastia AI alternatives](/blog/nastia-ai-alternatives/) roundup compares the apps that fix each one.
