The catalogue, not a blank prompt, is the starting point
VWaifu is an 18+ Mini App for conversations with AI characters. An age gate appears before the main interface, which opens on an empty chat list rather than a general-purpose assistant. The catalogue is divided into System and User characters and adds search, filters, like and dislike totals, and chat counts to each profile. The structure is closer to a roleplay library than to an open chatbot: a user selects a persona first, then starts a separate conversation.
Identity and scene are configured in separate builders
The character builder combines an image, name, fictional universe, gender, age, short description and a system prompt for personality, speaking style, behaviour and limits. A character can be marked private. The scenario builder handles the other half of the setup: cover image, title, one selected character or all characters, tags, situation, opening message and system rules for role, atmosphere and behaviour. It accepts the variables {character} and {username} in the first message and also offers a private flag. These controls are detailed, but a private label is not evidence of end-to-end encryption. Real people's images and identifying details should not be used without clear consent and a documented deletion route.
Free tokens depend on returning or promoting the service
The seven-day reward rises from 5 tokens on day one to 8, 12, 16, 21, 27 and 35. The first collected reward left 45 tokens visible in the account. Other routes are promotional: an invited friend is valued at 50 tokens, while the task list offers 10-token rewards for following channels and also promotes a TikTok task. Paid bundles range from 50 tokens for 35 Stars to 25,000 for 13,499 Stars; the same screen exposes Stars, SBP and crypto payment selectors. The final exchange rate, processor and refund terms matter more than the headline token count, especially for crypto payments.
Subscriptions mainly raise quotas and response priority
Plus costs 300 Stars for one month, 855 for three or 1,620 for six. Its visible limits include 10 characters, 10 scenarios, scenarios up to 5,000 characters, improved memory, five response regenerations, three message edits per day and five private characters and scenarios. Premium is 400, 1,140 or 2,160 Stars and raises the visible quotas to 50 characters, 30 scenarios, 12,000 characters per scenario, expanded memory and ten regenerations. Legendary costs 700, 1,995 or 3,780 Stars and advertises 120 daily tokens, up to 300 characters and 150 scenarios, maximum memory, almost unlimited regenerations, unlimited message editing, maximum priority, early access and unlimited private characters and scenarios.
The 18+ gate does not remove privacy and payment risks
The entry screen relies on the user confirming adulthood; the catalogue and user-created tags can lead to mature roleplay. Conversations may encourage intimate or emotionally sensitive disclosure, so personal information, real-world secrets and images of non-consenting people should stay out of prompts. The visible account menu links a user agreement and support, but the app should clearly explain message retention, deletion, moderation, private-character access and wallet handling before users rely on those labels. Stars and crypto purchases can also be difficult or impossible to reverse.
