Raydius (formerly OptiStudy) — Your academic life, understood.
Raydius is an AI study app for university students. Tell it what you are studying, add your syllabus and notes, and it turns them into a workspace that makes sense.
- Syllabus in, plan out. Upload a syllabus or handbook; get subjects, modules, topics and a study schedule around your exam dates.
- Ask your own notes. Upload lecture notes and ask questions — answers cite the page they came from.
- Past papers. See what is asked most, practise real questions and get them marked.
- Study groups with Ray. Invite friends, share notes, and ask Ray, the AI, with @Ray.
- Free to plan. Paid plans from ₹59 a month raise the AI limits. See pricing.
