## 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

## DeVoice

DeVoice positions itself as a complete transcription and audio-cleanup workspace rather than a single-purpose speech-to-text tool. You can paste a public media link from YouTube, TikTok, Instagram, X, or Facebook, upload a local file, or record straight in the browser, then get a timestamped transcript with automatic speaker separation. Every transcript is stored in a searchable history so old recordings stay findable, and inline editing means you can fix wording and save revised versions without leaving the page.

On top of transcription, DeVoice ships a set of audio utilities: background-noise removal, echo removal, an audio enhancer, an audio extractor, and audio/video trimmers. Subtitle workflows are covered through SRT and VTT export, and the AI translation and dubbing features let you push a finished piece into other languages or generate a translated voice track.

Summarization is treated as a first-class feature. The platform offers preset summary structures for meetings, creator repurposing, study notes, podcast show notes, and even court or case-review formats, so the same transcript can be reshaped into action items, chapters, or study material. Access is freemium: you can transcribe without creating an account, and heavier usage is metered through a credit balance topped up with one-time or subscription packs.

**Pricing & Plans:** Freemium. Basic transcription is available for free without an account, and heavier workloads run on a credit system with one-time top-up packs and subscription credits; promotional bonus-credit bundles are sometimes offered.

- **AI transcription in 100+ languages:** Convert uploaded files, public media links, or live recordings into accurate editable text, with automatic language detection across a wide range of languages.
- **Speaker diarization and word-level timestamps:** Speakers are labelled automatically so you can tell who said what, and clicking any line jumps the player to that exact moment.
- **Built-in audio cleanup tools:** Noise reduction, echo removal, an audio enhancer, an audio extractor, and trimmers let you improve and cut source audio before or after transcribing.
- **AI summaries with multiple formats:** Choose meeting, creator, study-note, podcast show-notes, or legal-style summary structures, and keep transcripts plus summaries stored and searchable.
- **Subtitle export and AI translation/dubbing:** Export SRT and VTT subtitle files for publishing workflows, and use the translation and dubbing tools to reach audiences in other languages.

**Strengths:** Free transcription without requiring an account lowers the barrier to trying it; Combines transcription, summarization, audio cleanup, and subtitle export in one workspace; Searchable transcript history with click-to-moment timestamps makes long recordings manageable; Wide language coverage and automatic speaker separation suit multilingual meetings

**Limitations:** Heavy transcription and dubbing volume is metered through credits, so costs scale with use; Feature depth means a busier interface than a single-purpose transcriber; Best results still depend on source audio quality despite the noise-reduction tools
