Frequently asked questions
Short, honest answers. Anything else, just ask Rae.
What is Rae?
Rae is an AI study companion on the web and in Telegram. Ask a question for an explanation, or upload your question and answer for feedback. Useful questions and notes stay organised by topic. Guided help stays separate from work you complete independently.
Is Rae free?
Your first study credit is free and needs no card. Check the pricing section for current plans and usage limits.
Which subjects does Rae cover?
Maths, the sciences, English, Chinese, Literature, History, Geography, Economics, Principles of Accounts, General Paper, Computer Science, Music and more. Rae will take a real attempt at any subject you throw at it, and the subjects on this site have dedicated exam-aware support.
Which exams does Rae support?
Rae supports Singapore exams including PSLE, N-Level, O-Level, SEC and A-Level. For supported subjects it uses syllabus context, past-year questions and marking guidance. For other courses, Rae works from materials you upload. Rae is independent and is not affiliated with or endorsed by MOE.
How is Rae different from a generic AI chatbot?
Rae starts with your schoolwork and keeps each question, answer and explanation together by topic. It can check many calculations with separate software and add sources to factual answers. AI can make mistakes, especially with subjective marking: check important work with your teacher or official materials.
Do I need to install anything?
No app installation is needed. Open Rae in your browser and sign in with email or Telegram. No Telegram account is required for the web app. You can also use Rae inside Telegram.
Can Rae help with past-paper style practice?
Yes. Rae generates exam-style practice questions matched to your level and syllabus, marks your attempts, and tracks the topics you are weakest in.
How is Rae designed?
Rae is built for Singapore syllabuses with teaching-informed design and exam-aware evidence checks.
