AI Hay - Hỏi đáp cùng AI

What is AI Hay?

AI Hay is an AI-based Q&A, learning assistance, and knowledge community application developed by the Vietnamese company AI HAY Joint Stock Company. The application is primarily in Vietnamese, but it also offers an English interface; it is suitable for obtaining local information and dealing with learning tasks related to Vietnam.

It can answer general knowledge questions, solve problems step by step, analyze images, allow for further inquiries, and display publicly available community answers. The existing “image processing” indication in the database is inaccurate; image recognition is just one of the methods used for inputting questions.

Main functions

1. AI Q&A and search

Users can pose questions in natural language, and the AI will generate answers by drawing on various data sources. According to the official app description, the answers include references that allow users to access the original information for further verification.

2. Step-by-step homework guidance

The platform supports learning tasks such as mathematics, language arts, and essay writing, providing steps and explanations. It covers the range from basic education to university levels, but the results it generates cannot replace the teacher’s explanations or the standard answers.

3. Photo recognition and problem solving

Users can take photos of assignments, test questions, emoji stickers, celebrities, objects, or food, so that the AI can identify them and provide answers. Errors are likely to occur when the images are blurry, partially obscured, the handwriting is illegible, or missing necessary information in the questions.

4. Continuous questioning

AI Hay retains the context of conversations on the same topic and suggests follow-up questions. Users can request additional details, alternative explanations, or comparisons between different viewpoints.

5. Multi-role AI chat

The application offers chatbots with various personalities and professional specialties, ranging from serious to casual in style. The character settings influence the way in which they communicate, but they do not imply that these chatbots possess actual professional qualifications.

6. Community knowledge discovery

Users can browse the popular and interesting questions and answers available in the community, and they can also choose to make their own content public. The terms of service state that user-generated content is private by default; it will only be made available to others after it is set to public and approved.

7. Social interaction

It allows communication with friends within the app, and includes features such as messaging, chatting, user-generated content, and social functions. Before posting, it is important to avoid revealing names, schools, contact information, location data, and chat privacy details.

8. Pro’s advanced capabilities

The Pro version offers unlimited assistance with tasks, search and Q&A functions, the latest AI models, advanced search and reasoning capabilities, as well as the ability to attach files up to 10MB in size. However, the actual lack of limits may still be subject to fair use policies, content restrictions, and system limitations.
