Hi Waifu

What is Hi Waifu?

Hi Waifu (also written HiWaifu) is an AI character chat and roleplay platform that runs in the browser at hiwaifu.com and as mobile apps for iOS and Android. The website introduces the product as an AI companion that cares, a place to have a friendly chat, roleplay and grow your communication and relationship skills.

Almost everything revolves around characters. The home page sorts the community catalog into tabs such as OC, Anime, Games, Helpers, Celebrity, VTuber, Movies & TV, Animals and RPG, and you can either pick an existing character or build your own before starting an open-ended text conversation or story.

The service is operated by LANGUAGE POWER MEDIA LIMITED, which lists a registered address in Kwai Chung, Hong Kong, in the contact section of its terms of use. The opening paragraph of the same terms names "Hi,Waifu Co., Ltd." as the provider of the services. The privacy notice begins instead with "Nexus, doing business as Hi,Waifu", so the legal pages use different entity names for one service.

A tech-business media report describes Hi Waifu as an AI emotional companion app with revenues exceeding 20 million yuan in 2024 and names Taojiang as its founder.

Core features

Hi Waifu combines a character catalog, a chat engine tuned for long stories, and a set of creator tools. The feature descriptions below come from the official website and from the vendor's own store listings.

Chat and reply style

• Novel-style replies: The Android listing says replies run several paragraphs, with narration, dialogue and sound effects laid out like the pages of a novel.
• Model selection: A chat setting lets you switch models, and the interface notes that model selection affects reply tone and detail.
• Adjustable reply length: You can choose a response length, and the Crystal cost of a reply varies with the length you select.

Memory, Lorebooks and personas

• Long-term memory: The vendor says long-term memory keeps track of what you share, so your AI companion picks up where the last chat ended.
• Memory Cards: When you build a character, Memory Cards hold the details that matter most, and you can drag them to set their priority.
• Personas: You can tell characters who you are and switch personas between stories.

Lorebooks are the tool for bigger fictional worlds. You write entries for places, factions, history or magic rules, and each entry is only pulled into the story when one of its keywords comes up in chat.

Voices, scene images and group rooms

• Character voices: Creators can pick a voice from the library or record their own for a character.
• Scene images: Creators prepare pictures for moods such as shy, happy or surprised, and the character sends the matching picture when the story reaches that moment.
• Video feed: You can swipe through short videos of characters and tap the character's name under a video to open a chat right there.
• Group chat rooms: Up to 10 characters can share one room around a topic or shared backstory, and they talk to each other as well as to you.

Publishing and the AI Creation Studio

A character you create can stay private, or you can publish it so other people can chat with it too. Published characters receive a score, and the platform states that a higher character score brings more opportunities for exposure.

The web app also contains an AI Creation Studio in which you chat with an agent to create character cards, short films, slides, images and videos. Its skill list includes a Story Short Film option that turns one idea into a complete narrative short with script, shots and footage.

Guide

Getting started

1. Sign up for an account, verify your email address, and then either create your own AI character or choose one that the community has already created.
2. Open the character and chat normally, or type what your character does in the action command box to move the scene forward.
3. Use the chat settings to set the model and response length; both change how replies read and what they cost.
4. Collect free Energy each day through the daily sign-in task on the Bonus page.

How Energy and Crystals are spent

Chatting draws on Energy, while Crystals are spent on actions such as longer replies and Creation Studio generations. Image generation for characters follows the same pattern: after the daily free usage limit is reached, each further generation consumes Energy. In the AI Creation Studio, the interface states that generation consumes Crystals only after you confirm, and it carries the warning that AI can make mistakes.

Hi Waifu use cases and examples

The product is built for long, character-driven conversations rather than quick question answering. The examples below come from the vendor's own descriptions of how the app is meant to be used.

• Text-adventure campaigns: Adventure characters can keep a status panel with your location, stamina and quest progress, which makes the AI roleplay app behave like a text adventure with a partner who keeps up.
• Everyday companionship and romance: The vendor pitches the catalog for finding an AI friend to talk to after work, a waifu or husbando for a slow-burn romance, or a rival for a sword-and-sorcery campaign.
• Writing and brainstorming: The iOS description positions the characters and custom personas as help with writing, brainstorming and safe social interaction.
• Large fictional worlds: Keyword-triggered Lorebook entries let big worlds stay consistent through long roleplay, so characters keep the details straight across many sessions.
• Ensemble scenes: Group rooms suit party-style scenes such as a class, a crew or a rival faction, since several characters can react to one another in a single thread.
• Fan media from a character: The Creation Studio can turn a character or idea into short films, cards, images or slides instead of plain chat.

Who is it for

Hi Waifu suits people who want an AI companion app for extended roleplay, including romance and mature storylines. Its interface asks anyone switching on NSFW content to confirm that they are over 18 years old and willing to view explicit content, and the pages checked this round describe no further age verification.

The age rules in the terms are stricter on paper than that toggle suggests, and they are not fully consistent. The terms set a minimum age of 14, ask users to affirm that they are over 18, an emancipated minor, or have parental or guardian consent, and then add that people under 13 should not use the service.

Likely good fits

• Adult roleplayers who want long, novel-style replies, memory that carries across chats and group scenes with several characters.
• Character creators who want to publish bots, build Lorebooks and be seen by other users.
• Creators hoping for direct support: users can send Crystals to a character's creator, and the platform takes a service fee of approximately 20% of each support amount.

Likely poor fits

• Anyone looking for a general-audience chatbot, since mature characters are part of the catalog and both app stores apply mature age labels.
• Teams or businesses that need a work assistant with guaranteed availability, which the terms do not offer.

Platforms

Hi Waifu is available in a web browser and through native mobile apps. The Android listing says chats can be auto-translated and that the app interface is offered in 15 languages.

On iPhone the listing states that the app requires iOS 15.0 or later. The US App Store page showed an age rating of 18+ and a score of 4.3 out of 5 from about 2.8K ratings when captured on September 28, 2026. On the same date, the Google Play listing showed a Mature 17+ label, 3.9 stars from about 110K reviews and 5M+ downloads, and it marks the app as containing ads and in-app purchases. These scores are aggregate store signals, not an evaluation of any specific feature.

Pricing

Hi Waifu is free to start, but chat runs on Energy. When Energy runs low you cannot continue a conversation; the in-app prompt tells you to top up Energy to keep chatting, or upgrade for more chat quota and the full model experience.

There are two ways to extend free use. The daily sign-in task grants Energy, and a Promotion Partner program pairs two users by code; once partnered, both need to sign in daily to get unlimited free chat until midnight the next day.

Plans and packs on iOS

Web checkout prices were not displayed on the pages checked this round. The US App Store listing showed the following in-app purchases on September 28, 2026:

The listing does not explain what each plan includes or how long SEASONLY lasts. On the website, an expired plan prompts you to renew to keep long memory, premium chat and no-watermark downloads, which indicates the main membership perks. The terms say premium membership can be charged monthly, every three months or every six months.

Renewal, cancellation and refunds

• Auto-renewal: Premium membership is a subscription that continues and renews automatically until terminated, and it can be cancelled before it renews.
• How to cancel: The terms say you can cancel at any time by contacting customer service at hiwaifuapp@outlook.com.
• No refund for the rest of the period: After cancelling, benefits last until the end of the month with continued access, but you will not receive a refund.
• Coins: Any coin purchases are final and non-refundable unless otherwise required by law.
• Upgrades: When an upgrade succeeds, the current membership ends and its unused portion is refunded proportionally, according to the in-app upgrade notice.
• Switching plans: The site asks you to cancel an active subscription before subscribing to another plan to avoid duplicate charges.
• Deleting your account: The account deletion notice says to cancel any subscription manually on the payment platform first; otherwise, you may still be charged for renewals.

Hi Waifu alternatives

Several character chat platforms overlap with Hi Waifu, and the practical differences are in content policy, creation tools and how chat is metered.

• PolyBuzz: Its website advertises free AI chat with 20M+ AI characters, AI chat roleplay and creating an AI girlfriend. It covers the same romance and roleplay territory as Hi Waifu with a much larger stated character count.
• Emochi: Its website advertises unrestricted free chats with 1,000,000+ anime and fantasy characters and lets you design and customize any characters. Its anime and fantasy focus overlaps with Hi Waifu's Anime tab.

Both competitors lead with free chat in their own marketing, whereas Hi Waifu meters chat with Energy and sells Energy, Crystal and subscription options.

Limitations

Content rules

Hi Waifu's reviewer rules state that NSFW characters are allowed on the platform, but the picture, name, description, greeting and background of every character must stay clean, while child safety, hate, real violence, illegal content and spam break the rules anywhere in a character. Hi Waifu also reserves the right to remove content without prior notice.

Service and usage terms

• No uptime promise: Hi Waifu makes no uptime guarantee for the service. The terms also say you are not entitled to a refund or compensation for suspensions.
• Reuse of material: The terms say you may not reproduce, distribute, sell, license, copy, modify or otherwise use information obtained through the service for profit, which matters for anyone planning to reuse generated stories or images commercially.

Privacy, data use and deletion

Hi Waifu runs an optional reply comparison test in which you pick the better of two replies, and its notice says conversations you label may be used for analysis and model training. The same notice says you can opt out of the test anytime in Settings. It also asks participants not to share personal private information in chats. The privacy notice checked this round does not say whether ordinary chat messages are used to train models, and it does not describe how chat content is stored.

• Collected data: The privacy notice says Hi Waifu collects email addresses, names and other similar information.
• Internal research: Personal information may be used for internal research for technological development and demonstration.
• Retention: The notice says no purpose in it requires keeping personal information longer than the period in which users have an account.
• Deletion: Upon a request to terminate an account, Hi Waifu will deactivate or delete the account from active databases, but may retain some information to prevent fraud, handle investigations, enforce its terms or meet legal requirements.
• In-app deletion scope: The in-app notice says deleting your account also deletes the characters you created and your chat history.
• Store privacy labels: The iOS privacy label lists purchases, contact info, search history, identifiers and usage data as data that may be used to track you across other companies' apps and websites. The Android data safety section says the app may share location, app activity and two other data types with third parties.

FAQ

Q1. Is Hi Waifu free to use?

You can sign up and chat without paying, but chat consumes Energy. Daily sign-in rewards and the Promotion Partner program extend free use, and paid options include subscriptions and Energy, Crystal or Diamond packs; the US App Store listing showed MONTHLY at $12.99 and SEASONLY at $29.99 on September 28, 2026.

Q2. Does Hi Waifu allow NSFW content?

Yes. The platform's rules allow NSFW characters as long as their public-facing picture, name, description, greeting and background stay clean, and showing NSFW content requires confirming that you are over 18. Content involving child safety violations, hate, real violence or illegal material is not allowed anywhere.

Q3. How do I cancel a Hi Waifu subscription?

The terms say you can cancel by contacting hiwaifuapp@outlook.com, and access continues for the rest of the period without a refund. If you subscribed through a payment platform, the account deletion notice says to cancel there manually, because deleting the account alone may not stop renewals.

Q4. Are my Hi Waifu chats used to train AI models?

Conversations you label in the optional reply comparison test may be used for analysis and model training, and you can leave that test in Settings. The privacy notice checked this round does not address whether other chat messages are used for training.
