Raku AI
How Raku AI works
Raku AI is an AI study assistant for mobile devices. It helps you work through a question, understand the reasoning and ask about the parts that are unclear.
Explore the example solution ↗Start with your question
Take a photo, choose an image from your gallery, or type a question. Include the full question and any diagram or answer choices. A clear image gives the assistant the information it needs to interpret the problem.
Read the reasoning and ask a follow-up
The written explanation breaks the solution into steps. If a formula, calculation or idea is unclear, ask a follow-up question in the same conversation. You can return to saved questions in your library when you revise.
Request a video explanation
For supported questions, you can request a video after the written solution. Video availability depends on your plan and usage entitlements. The app shows the relevant information before you request a video.
A buoyancy example
A block floating in equilibrium has a buoyant force equal to its weight. If the liquid becomes denser while the block keeps floating, less of the block needs to be submerged to support that weight. The submerged volume decreases; the buoyant force stays the same.
Use answers thoughtfully
AI-generated explanations can contain mistakes. Check the steps and compare uncertain results with a reliable textbook, teacher or course resource. Raku AI does not guarantee correct answers or exam results.
Availability and pricing
Raku AI is currently available through early-access invitations. Joining the waitlist does not provide immediate access. The app offers subscriptions and additional usage packs; current prices, billing terms and limits are shown in the app before purchase.
Your questions and your privacy
Relevant question content and conversation context are processed to provide explanations. Crop photos to the question and avoid including names, faces or student identifiers. Our privacy and account-deletion pages explain data handling and how to make a request.
