A friendly Vietnamese AI study assistant for homework, images and everyday questions
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.
Work through maths problems and literature or essay tasks with detailed reasoning so students can follow the method, not just the result.
Upload or point at a photo to identify objects, scenes and well-known public figures, using Vietnamese-language context.
Decode internet memes, visual jokes, riddles and trick questions that general-purpose assistants often misread.
Text to speech and voice AI across every device
Listen to books, PDFs, documents and web pages read aloud in a large library of lifelike AI voices.
Dictate instead of typing in almost any app, across Google Docs, Gmail, Slack, Outlook and more.
Turn documents or a short prompt into an AI podcast, and get instant summaries of what you are reading.
Use the web app, Chrome and Edge extensions, and native iOS, Android, Mac and Windows apps.
