About Nastia
Nastia AI is an uncensored AI companion platform built around a two-week memory system that tracks conversation history, personality dynamics, and user preferences across sessions. The platform supports text chat, voice messages with emotional inflection, AI image generation, and video creation across web, iOS, Android, and PWA. Nastia differentiates itself through adaptive sentiment analysis that reads user mood and adjusts conversational tone in real time. Users can build custom companions with full control over personality traits, appearance, voice, and behavioral patterns, and engage multiple AI characters simultaneously in group chat scenarios. The free tier includes NSFW text chat with daily message limits and requires no credit card. Premium starts at $11.99/month for Standard (voice, images, extended memory) or $15.99/month for Unlimited (adds video generation and priority access), with annual billing dropping to $4.17/month. Important caveat: Trustpilot reviews (2.5/5, 67% one-star) report severe billing irregularities including unexpected charges and near-impossible refunds. The company is registered in France as Nastia Cybernetics. Users considering a subscription should use a virtual card and monitor charges carefully.

Frequently Asked Questions
Yes, Nastia has a free tier with daily message allocation, core text chat including NSFW, and one AI companion. No credit card is required. Premium plans start at $11.99/month (Standard) or $15.99/month (Unlimited). Annual billing drops to as low as $4.17/month. Image and video generation require a paid plan.
Nastia retains conversation history for up to two weeks. Your companion remembers past scenarios, personality dynamics, and conversational preferences across sessions. Beyond the 14-day window, specific details gradually fade, though established personality traits persist longer. Within the active window, continuity is strong.
Text chat is largely uncensored with fewer filters than mainstream competitors. However, user reports indicate that image generation applies content restrictions despite the platform marketing itself as fully uncensored. The free tier includes NSFW text chat, but media generation is more restricted than advertised.
The company is registered in France (Nastia Cybernetics, SIREN: 982046385) and uses discreet billing. However, Trustpilot reviews (2.5/5, 67% one-star) report billing problems: annual charges when monthly was selected, charges exceeding expected amounts, and difficulty obtaining refunds. Using a virtual card is advisable.
Nastia has stronger memory continuity and much lower pricing (from $4.17/month vs Candy AI's $12.99/month). Candy AI offers superior multimedia generation, faster response times, a larger pre-built character library, and far fewer billing complaints. For conversational depth on a budget, Nastia wins. For reliability and media quality, Candy AI is the safer choice.
