## AI Hay

AI Hay is a domestic Vietnamese AI assistant whose name literally means "ask well, answer well." Its positioning is deliberately broad and informal: rather than a specialist exam-prep tool, it answers whatever a Vietnamese-speaking user throws at it, from a maths problem and an essay outline to "what is in this photo?" or "explain this joke." The interface is a straightforward chat box, which keeps the barrier to entry low for school students and casual users alike.

A notable part of its feature set is image understanding combined with local cultural context. Beyond standard object recognition, AI Hay advertises the ability to identify well-known Vietnamese public figures and to explain internet memes and visual jokes — a nod to how much of young users' daily conversation happens in images and screenshots. The riddle and trick-question solving feature hits the same note: it is a playful companion as much as a study helper.

On the academic side, the assistant covers maths and writing in a step-by-step style rather than simply handing over a final answer, which matters for users who want to understand a method rather than copy it. Because the whole product is delivered in Vietnamese and tuned to local curricula and references, it is often more useful to Vietnamese students than a generic global chatbot, even if the underlying capability set is similar.

**Pricing & Plans:** AI Hay is listed as free to use, with no subscription required for its core chat, homework and image-recognition features. Because the product is ad- and audience-oriented, availability and any future paid tiers are best confirmed on the site itself; no specific paid pricing is published at the time of review.

- **Homework and study support:** Ask a question in natural Vietnamese and get explanations covering a wide range of school subjects, framed as guidance rather than a bare answer key.
- **Step-by-step maths and writing help:** Work through maths problems and literature or essay tasks with detailed reasoning so students can follow the method, not just the result.
- **Image recognition and celebrity identification:** Upload or point at a photo to identify objects, scenes and well-known public figures, using Vietnamese-language context.
- **Meme and riddle explanation:** Decode internet memes, visual jokes, riddles and trick questions that general-purpose assistants often misread.
- **Everyday smart tips:** Get quick practical suggestions for common daily questions alongside the more academic features.

**Strengths:** Fully Vietnamese-language experience tuned to local curricula and references; Combines study help with image recognition and meme or riddle explanation in one chat; Free to use with no sign-up friction for basic questions; Explanations aim at method and reasoning rather than just final answers

**Limitations:** Answers should be checked against textbooks, since AI explanations can contain errors; Feature depth varies by subject and there is no published syllabus coverage list; Pricing and any premium tiers are not clearly documented on the site

## StudyTool

StudyTool positions itself as an exam assistant rather than a general-purpose chatbot. Its design assumption is that the question already exists on screen in a structured format, so the useful work is capturing it precisely and returning a clear answer fast. The extension therefore focuses on two input methods: a snapshot capture that grabs any question from any website, and a text selection flow where you highlight a question, right-click and choose Ask StudyTool.

Compatibility is the core selling point. Instead of targeting one platform, StudyTool claims to work across the learning management systems students actually use, including Canvas, McGraw Hill, Blackboard and Moodle. Answers arrive inside the extension popup rather than in a separate window, and each one can be accompanied by a detailed explanation so you can see the reasoning behind a choice rather than just the letter.

The tool also includes a few features aimed at discretion and review. A stealth mode integrates the software into the platform's own interface elements, and the developer states that data is anonymized and that the extension is designed to remain undetectable on compatible platforms. A solved questions history lets you revisit recent questions and reread the reasoning, with a Do Not Track option to keep new questions out of that history. It is a specialist tool with a narrow purpose, and it is honest about what that purpose is.

**Pricing & Plans:** Available as a free Chrome extension with optional paid capabilities, categorised as freemium. The store listing itself does not publish specific subscription amounts, so check the developer site for current pricing.

- **Multi-platform LMS support:** Works with popular learning management systems including Canvas, Blackboard, Moodle and McGraw Hill, rather than being tied to a single one.
- **Snapshot capture:** Grab any question from any website directly into the extension and receive an answer in the popup, which is especially useful for multiple-choice items.
- **Right-click text selection:** Highlight a question on any site, right-click and choose Ask StudyTool to bring up a popup with the answer.
- **Detailed explanations:** Each solution includes reasoning about the underlying concept so you can understand why an option is correct.
- **Solved questions history:** Review and revisit recently solved questions to reinforce understanding, with a Do Not Track option to exclude new questions from the record.

**Strengths:** Covers the LMS platforms students actually use, including Canvas, Blackboard, Moodle and McGraw Hill; Two different capture methods, screenshot and text selection, so it fits whichever workflow you prefer; Answers include reasoning rather than just a choice, which is more useful for genuine revision; Solved questions history with a Do Not Track toggle gives you control over what gets recorded

**Limitations:** Narrowly focused on quiz and homework answering rather than broader study or note management; The stealth and undetectability positioning sits in ethically grey territory that many institutions prohibit; Detailed pricing for the paid tier is not published on the extension listing itself
