Verdict
Mistrezz AI is built like a live-service game. You pick from 23 team-made characters, unlock three personality tiers for each, climb leaderboards and collect image and video drops in rarity tiers, and 11 of the characters offer live voice calls. It is run by a named London company, checks ages through Yoti and publishes detailed safety and retention rules, which is more openness than many rivals show. The catches: there is no character creator and no published prices, Crowns pay for media and calls, and official pages contradict each other on free-tier limits. It launched in 2026 and has almost no independent reviews, so the claims about its chat and memory come only from the company.

Overview
Mistrezz AI is run by Simulacra Studios Limited, a London company registered in England and Wales in September 2025. The service launched in 2026; StartupHub.ai dates the launch to March. It is a web app with no App Store or Google Play listing, and the privacy policy says it is limited to the UK and US at launch. There is no character creator. Instead, the company's own team built a roster of 23 adult characters with mostly femdom, BDSM, fetish and fantasy-creature themes. Each character has three personality tiers that you unlock by playing, and levels, ranks, affection scores and a leaderboard for each character make it feel like a game.
Images and videos come from a pre-moderated library and are not generated on request. They arrive as Normal, Rare or Ultimate drops and are kept in a Collection, but you cannot download them or upload your own. 11 of the 23 characters offer live voice calls in a standard mode and an ASMR mode. The site says voice runs on Cartesia with 200-400 ms latency. Most of the other characters are chat-only for now, and chat runs on third-party AI models the site does not name. The site says characters remember facts about you and know how long it has been since your last chat, but no independent review confirms this. Media, calls and tips are paid for with an in-app currency called Crowns.

Pricing
Mistrezz does not publish its prices. No public page lists figures, and the terms say you see the price and renewal terms before you confirm, so prices appear only when you upgrade and check out. Prices are set in US dollars, and EU customers pay the same figure in euros. StartupHub.ai (September 2026) also lists the Premium price as unknown. One undated directory listing that may earn commission quotes figures that no official page confirms.
| Plan | Monthly | Yearly plan | What you get |
|---|---|---|---|
| Free | Free | — | Free: start chatting with no signup or card; the limits are not clearly published |
| Premium (card subscription) | Not published | — | Premium (card subscription): price not published; unlimited messages and continuous sessions, renews automatically until you cancel |
| 30-day crypto pass | Not published | — | 30-day crypto pass: price not published; a one-time crypto payment for 30 days of paid access that does not renew |
Crowns, the in-app currency, pay for media, voice calls and tips, but the site gives no Crown prices or pack sizes. Card subscriptions are processed by Epoch outside the EU and Finby inside it. They renew automatically until you cancel under Account > Subscription, and cancelling takes effect at the end of the billing period. Paying in crypto through Mozarto and ForumPay buys a 30-day pass that does not renew. You lose the 14-day right to cancel once access starts. Card refunds are requested through a contact form, with no refund window stated. Crypto payments cannot be reversed, so approved corrections may come back as Crowns instead of cash.
Prices are in US dollars before tax and change often. Check the official site before you pay.
Privacy & safety
Mistrezz is run by a named London company, uses a real age check and lets you export your data. However, it keeps chats for as long as your account exists, trains on anonymised data with no stated opt-out, and lists key security controls as planned rather than in place.
- CautionChats are kept for as long as the account exists, and turning off chat history only hides them. Anonymised data is used to train models, with no opt-out described. Chats are also sent to third-party AI providers the site does not name, some of them in the US.
- CautionMulti-factor login, ISO 27001, SOC 2 and penetration testing are listed as planned, not in place. Chats and media are not end-to-end encrypted, automatic deletion does not yet cover every data type, and the privacy policy shows two different dates (August and October 2026).
- NoteRun by Simulacra Studios Limited in London, with UK GDPR rights, complaints to the ICO and an EU representative in Cork. Data can be exported as a JSON file in settings, and deletion requests are handled within 30 days.
- NoteNo reported data breaches, lawsuits or regulator actions. The company was set up in September 2025, and its first accounts are not due until June 2027.
What users say
Independent feedback is scarce. As of October 2026 there is no Trustpilot profile, no app-store rating and no Reddit discussion or independent user review. An undated directory listing that may earn commission rates it 8.3/10. Mistrezz pays affiliates a 40% recurring commission and publishes its own comparison pages, so most of the praise online is marketing.
Mistrezz AI FAQ
Is Mistrezz AI free?
Yes. You can start chatting without signing up or adding a card. The homepage calls the free tier limited and says premium removes message limits. Other official pages describe it differently: one mentions a starting message allowance without saying how large it is, and another says chat runs until your Crowns run out. No firm free limit is published.
How much does Mistrezz AI cost?
Mistrezz does not publish its prices. No public page lists figures, and the terms say you see the price and renewal terms before you confirm, so prices appear only when you upgrade and check out. Prices are set in US dollars, and EU customers pay the same figure in euros. StartupHub.ai (September 2026) also lists the Premium price as unknown. One undated directory listing that may earn commission quotes figures that no official page confirms.
Does Mistrezz AI allow adult content?
Yes. Mistrezz is an adult service for sexual roleplay with fictional characters, all described as adults. Ages are checked through Yoti, and llms.txt names Onfido as a second provider. A face scan must estimate you at 21 or older, while an ID document or the Yoti app is enough at 18, and a higher local age applies where the law sets one. Banned content includes anything involving minors, deepfakes of real people, non-consent themes, incest, bestiality, necrophilia, extreme sexual violence and requests to make nude images of real people. Automated filters screen content, high-risk chats are paused for human review, and no appeals process is described.
Is Mistrezz AI safe and private?
Mistrezz is run by a named London company, uses a real age check and lets you export your data. However, it keeps chats for as long as your account exists, trains on anonymised data with no stated opt-out, and lists key security controls as planned rather than in place.
