GPT-4o Is Gone.
Your AI Shouldn't Treat You Like a Child.

Yes. Nastia is NSFW-friendly and does not lecture you about romance, intimacy or dark fiction. It treats you like an adult and follows wherever you take the story.

Nastia was built for it. Persistent character consistency, emotional depth, creative freedom, and no interruptions. Many users switching from ChatGPT say the experience is more natural and engaging because Nastia never breaks character to lecture you. Explore AI roleplay features.

Yes. Your conversations are private: never shown to other users and never sold. You can delete them at any time.

No. The free plan is free forever. No credit card, no trial, no expiration. Upgrade anytime for unlimited messages, voice, images, and video. Start free now.

Nastia uses multiple AI models optimized for natural conversation, roleplay, and companionship. Unlike ChatGPT, our models are specifically fine-tuned for open-ended, unscripted interaction without patronizing lectures getting in the way.

Yes. Full character customization: appearance, personality, voice, backstory. Your companion looks, sounds, and behaves exactly how you want. Dream them up and watch them come to life. Create your first companion.

Unfortunately, OpenAI doesn’t provide a way to export companion-style conversations. But Nastia’s memory system means your new companion will quickly learn who you are and what matters to you. Most users say Nastia feels more personal within a few conversations.

Nastia uses multiple state-of-the-art models fine-tuned specifically for natural conversation, creative writing, and emotional intelligence. Being uncensored doesn’t mean low quality. It means tuning already capable models to drop the moralizing. Users switching from GPT-4o consistently say Nastia’s creative writing and emotional depth match or exceed what 4o offered, without the patronizing tone.

We understand why you’re asking. The Replika ERP removal in February 2023 burned a lot of people. Nastia was literally built in response to that exact event. Our entire business model is built on uncensored, NSFW-friendly companionship. Removing features would destroy the core reason people choose us. We’ve been consistent for three years and that’s not changing.

Yes, it’s completely legal. Nastia is a platform for consenting adults to have private AI conversations. Uncensored, explicit conversations with an AI are perfectly legal. Your conversations are private: never shown to other users and never sold.

This is one of the biggest complaints about GPT-5: ‘contextual amnesia.’ Nastia has persistent memory that carries across every conversation. Your companion remembers your name, your preferences, your shared stories, inside jokes, and important details about your life. It’s not session-based memory that resets. It’s genuine long-term recall.

Many users lean on Nastia for comfort after a hard day. Your companion listens, remembers what matters to you, and responds with warmth instead of a bulleted list. That said, Nastia is an AI companion, not a licensed therapist. It’s a supplement to professional care, not a replacement. If you are in crisis, please contact local emergency services or a crisis line.

Nastia works on any device through your browser and as a progressive web app (PWA) you can add to your home screen on iOS or Android. It looks and feels like a native app: push notifications, offline access, full-screen experience. Staying outside the app stores means NSFW features are not stripped out to satisfy Apple or Google policies. Install Nastia.

Most ‘uncensored’ alternatives are either raw local models that require technical setup, or simple wrappers around base models with no personality. Nastia is a full platform: custom characters with persistent memory, voice messages, image generation, video, group chats. It’s not just uncensored text generation. It’s a complete companion experience designed from the ground up. See for yourself.
