Nastia

Nastia is a web-based AI companion service built around uncensored one-on-one chat with an adult persona. It is aimed at users who want an unfiltered conversational partner for NSFW roleplay, sexting and dirty talk, and it positions itself explicitly as an alternative to Character.AI and Replika, both of which restrict or removed adult content. The site also frames the companion as an emotional-support tool for people who want a non-judgmental listener, so the same account covers both casual daily conversation and explicit roleplay.

Beyond text chat, the platform includes voice messages from companions, an AI image generator and an AI video generator. Media can be requested conversationally (asking the companion for a picture) or produced through an advanced generator where the user writes their own description. A group chat mode lets several AI companions interact with each other while the user participates. Companions are described as responsive to the user's interests and able to sustain long-running personal context rather than isolated exchanges.

Nastia runs on a freemium model. The free tier requires no credit card and includes a daily message allowance plus basic features, which is enough to test chat and roleplay before paying. Paid plans unlock unlimited messaging, voice chat, uncensored image generation and other premium features; the company does not publish plan tiers or prices on its landing page, so the actual cost is only visible after visiting the pricing section or signing up. Subscriptions can be cancelled from Settings, with access continuing until the end of the billing period.

On privacy, the service states that conversations are encrypted, data is not sold to third parties, and both the account and all generated content can be permanently deleted from Settings. The main limitations are practical: the free tier is capped by daily messages, and the most-used features (voice and image generation) sit behind the paywall. The lack of transparent public pricing, model details, or generation limits makes it hard to compare against competitors before registering. As with any companion app marketed for mental wellness, the emotional-coaching claims should not be treated as a substitute for professional support.
