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.
Turn your own notes and PDFs into lessons, flashcards and exam practice
Import PDFs, Word docs, PowerPoint, Excel, pasted text, YouTube videos, web links and Google Drive files into a single study space, with OCR for scanned PDFs.
Four study modes built from the same material: guided lessons, spaced-repetition flashcards, out-loud teach-back sessions and adaptive practice tests.
Written answers get graded by AI and quiz difficulty adjusts to how you are actually performing, so weak topics get repeated more often.
Pro builds question banks and timed mock exams for targets like NCLEX-RN, MCAT, USMLE Step 1, the CPA Exam and CompTIA Security+, then points you at the areas to revisit.
SpecialistProvides superior reasoning and multi-subject tutoring, but requires custom prompts rather than dedicated study widgets.
