Nastia AI Review

Nastia lets you create or pick AI companions and talk to them one to one or in group chats with several companions. Companions can send voice messages, and the app includes image and video generation. Nastia positions itself against mainstream companion apps by allowing adult roleplay: its terms permit fictional sexual content between adults and prohibit anything involving minors, real identifiable people or non-consensual activity, among other categories.

There is no App Store or Google Play app. You use Nastia at nastia.ai in a browser, or install it as a progressive web app: on iPhone this requires Safari (Add to Home Screen), and Android and desktop are also supported. Sign-in is by Discord, Google, Apple or email. The service is run by Nastia Cybernetics, a French company, and its terms are governed by French law.

Nastia's membership page sits behind a sign-in, and neither the homepage, the terms nor the refund policy lists plan names or dollar amounts, so we cannot quote a price. What the vendor's pages do say: payments are in US dollars, subscriptions renew automatically until cancelled, cancellation takes effect at the end of the paid term, and "all purchases are non-refundable" except where required by law or a technical error prevented delivery. Prices may change at any time. You cancel from Settings, Membership, Manage, Danger Zone in the app.

Prices checked on the vendor's pricing page on November 1, 2026. See Nastia membership (sign-in required) and the refund policy.

What Nastia lists on its homepage, install page and terms:

Nastia suits adults who want a companion chat with fewer content restrictions than mainstream apps, who like group chats with several characters, and who are comfortable using a web app instead of a store app. The free tier lets you judge it without a card.

Look elsewhere if you want published prices before you sign up, refunds, or a native store app. Replika and Character.AI are mainstream, filtered alternatives with store apps; Kindroid and Nomi are companion apps known for memory and customisation; Candy AI is a direct adult-companion rival.

Feedback is mixed to negative and based on a small sample. On Trustpilot Nastia had a TrustScore of 2.1 out of 5 from 19 reviews on an unclaimed profile; complaints centre on unexpected or higher-than-expected charges and hard-to-get refunds, slow or failing image and video generation, and companions forgetting details, while a few reviewers praise realistic one-to-one conversation and voice chat. RoboRhythms' October 2026 review (affiliate links disclosed, and it recommends competitors) credits the free tier, group chats and generator, but flags no refunds, auto-renewal, long or flattering replies, memory drift in long chats, no store app and no one-click data export.
