Overview

Nastia AI positions itself as the uncompromising privacy-first AI companion with absolutely zero content filters. The platform fully embraces explicit content while promising that conversations are never read by humans, never used for training, and can be permanently deleted at any time — a rare combination of unrestricted content and genuine privacy commitment.

Features include persistent memory across sessions, customizable characters with full control over name, appearance, personality, voice, and backstory, voice chat, AI image generation, group conversations, and text-based roleplay. One free companion is available forever with no time limit, making it possible to experience the core product without paying.

Premium plans start at $4.17/month for enhanced features including additional companions and higher-quality image generation. The platform is available on web, iOS, and Android. Nastia appeals to users who are frustrated by content filters on other platforms and want complete conversational freedom paired with strong privacy protections.
