AI Hay
Vietnamese AI assistant with 15+ expert chat agents for homework, writing, tarot and everyday questions
For Vietnamese-language tasks that global assistants handle clumsily — exam-style homework, lục bát poetry, tarot and numerology readings — AI Hay is the more culturally fluent choice, and it costs nothing to try. The trade-off is real: narrower depth on hard reasoning, no developer tooling, and health or psychology agents you should treat as entertainment, not clinical advice. Use it next to ChatGPT or Gemini, not instead of them.

Skip AI Hay if you need English-first output or a tool you can build your own product on top of — it is a Vietnamese-language assistant aimed at students and everyday users, not a platform for professional multi-step work.
AI Hay sits at the free end of the market: the page offers free account creation that saves your conversation history, and none of the 15 listed agents is gated behind a paid tier on the page as scraped. That undercuts ChatGPT, Gemini and Claude for Vietnamese-language everyday tasks, where those tools require a paid plan for sustained use. It is also cheaper than Vietnamese-market study apps that charge for homework help.

About AI Hay
AI Hay is a Vietnamese-language AI assistant organized as a menu of specialist chat agents rather than one general chatbot. You pick the agent that matches the task — Giải bài tập for step-by-step homework help, Hiểu sâu for deeper explanations, AI Viết văn for essays, Tạo PPT for slide decks, Tạo ảnh for image generation, and Quiz flashcard for revision — and the conversation stays in Vietnamese throughout. Study help and writing cover the academic side; the rest of the shelf is culturally specific. The vendor publishes live chat counters, and they reveal what people actually use: the Tarot agent at 2.9M chats and Thần số học (numerology) at 1.7M sit far above functional tools. Tư vấn sức khỏe (health advice) has 1.1M chats, Tư vấn tâm lý (psychology) 778.6K, Trợ lý viết truyện (story writing) 631K, and Trợ lý làm thơ (poetry — lục bát, free verse, flirty verse) 532.7K. Utility agents run lower: the sales-caption writer at 433.5K, the nutrition planner at 317.8K, career counselling at 304.6K, the translator at 276.3K, and the email drafter at 103.2K. Beyond chat agents, AI Hay bundles AIHay Drive as a file workspace, Sơ đồ tư duy for mind maps, image recognition for objects and text, and voice input for hands-free use. The translation agent is positioned directly against Google Dịch, and the caption writer targets Facebook and Zalo sellers writing product posts in Vietnamese. Accounts are free, and signing in saves conversation history. Against ChatGPT, Gemini or Claude, AI Hay trades depth, ecosystem and developer tooling for Vietnamese-language relevance and agents that simply don't exist in global assistants — tarot, numerology, lục bát poetry, Vietnamese exam-style homework solving. Treat it as a companion to a global model, not a replacement for demanding work.
Behind the Verdict
The interesting thing about AI Hay isn't the chat interface — it's the usage data the vendor puts on the homepage. A tarot reader with 2.9M chats and a numerology agent with 1.7M tell you something no Western assistant's metrics will: Vietnamese users want culturally rooted agents, not another blank prompt box. If that's your use case, nothing from OpenAI or Google competes directly. We'd reach for AI Hay when the task is Vietnamese-first. Homework via Giải bài tập, essays via AI Viết văn, slide decks via Tạo PPT, revision flashcards, Facebook or Zalo sales captions — these are the jobs where a Vietnamese-native tool beats a translated English one. The free account removes the risk of trying it: log in, keep your history, decide later. Where it bites: depth. Long, multi-step reasoning and nuanced English-language output are not where this tool shines, and there's no API or SDK for developers who want to build on it. High-volume or mission-critical workflows shouldn't depend on it either. On health, nutrition and psychology, the agents are fluent and engaging — 1.1M chats on health advice is not a rounding error — but they are chat tools, not licensed professionals. We'd use them for general orientation and then see a real doctor or therapist for anything serious. The closest alternatives are the global assistants. ChatGPT, Gemini and Claude win on reasoning depth, ecosystem and integrations; AI Hay wins on Vietnamese relevance and on the specific agents that only make sense in a Vietnamese context. Running both is the honest answer, not picking a side. For students, small online sellers and anyone curious about tarot or Vietnamese verse, the value proposition is straightforward enough: a free, native-language assistant that does a handful of things global tools

Real-world workflow fit
Concrete scenarios for the personas AI Hay actually fits — and what changes day-one when you adopt it.
You photograph a maths problem, paste the text into Giải bài tập, ask for the steps, then have Hiểu sâu explain the underlying rule and turn the topic into Quiz flashcards.
Outcome: A worked solution plus revision material in Vietnamese, without paying for a tutor or translating the problem into English.
You paste rough product details into Trợ lý viết content bán hàng, get several Vietnamese status options, then use Tạo ảnh to make a matching image and the caption agent to shorten one for a story post.
Outcome: Ready-to-post Vietnamese sales copy and imagery produced in a single session.
You open the Tarot or Thần số học agent for a reading, then switch to the translation agent to check an English phrase and the nutrition agent for a calorie count on dinner.
Outcome: Entertainment, translation and a meal estimate from one free account that retains the conversation history.
Use Cases
- Ask Giải bài tập to walk through a maths problem step by step in Vietnamese
- Use Hiểu sâu to get a topic explained more deeply than a one-line answer
- Have AI Viết văn draft a Vietnamese essay, then turn it into slides with Tạo PPT
- Upload a photo of a plant or a page for image recognition and follow-up questions
- Translate English and Vietnamese text or learn vocabulary with the translation agent
- Generate Facebook or Zalo sales status posts from rough product details
- Get a keto or eat-clean meal plan with calorie figures from the nutrition agent
- Ask tarot, numerology or lục bát poetry agents for culturally specific output
Limitations
- AI Hay is scoped and marketed as a free tool for casual and educational use, so it is not aimed at high-volume or enterprise workloads.
- The specialist agents are narrow by design: the email agent, caption agent and translation agent each handle one job rather than a multi-step professional workflow.
- The health advice, psychology consultation, tarot and numerology agents are chat personas — useful for reflection and general information, but not clinical or predictive tools.
- The interface and every agent are Vietnamese-first, so if you work primarily in English this is not the product for you.
- AIHay Drive is a file workspace rather than a document ecosystem you can build team processes around.

Switching to or from AI Hay
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From a general global assistant: import nothing — paste your Vietnamese text into AI Hay's translation or Viết văn agent and keep the global tool for English and hard reasoning.
- →From paper homework help: move to Giải bài tập for step-by-step solutions, then use Quiz flashcard to convert the topic into revision cards.
- →From a paid Vietnamese study app: recreate your revision sets as Quiz flashcards and mind maps in AI Hay before cancelling.
- →From ChatGPT or Gemini: keep AI Hay as the Vietnamese-language layer for captions, essays and cultural agents, since agent scopes differ from a general chat thread.
- ↗To ChatGPT, Gemini or Claude: export any essay or slide text you produced in AI Viết văn or Tạo PPT and continue there when you need deeper multi-step reasoning.
- ↗To a dedicated Vietnamese study app: rebuild your Quiz flashcard sets there if you need structured curriculum tracking.
- ↗To a paid translation API: move any high-volume translation work off the chat agent if you need it embedded in your own software.
