StudyNinja is a cloud study companion that puts to-do lists, notes, a calendar, study goals and assignment management in one place, with an AI tutor on top. The tutor answers questions on any subject and keeps a history of earlier chats. Notes can be shared with classmates and exported as PDF or Word. The free Starter plan includes 500 MB of storage and 500 text tokens per month, while Standard at $9.99 per month and Ultimate at $19.99 per month raise storage and token limits and add sharing and resource storage.
It is aimed at students who juggle deadlines across several courses and want one organized workspace. Study groups can use the shared notes and collaborative documents to work on joint assignments. Students who prefer to write their own drafts can use the AI writing support as a helper. Because it runs in a browser on a PC, tablet or phone, there is nothing to install, which suits learners who switch between a laptop at home and a phone on campus. Anyone who wants a plain planner with an AI tutor attached, without paying up front, can begin on the free plan with no credit card.
Typical use includes setting a semester goal and tracking progress against it, listing assignments with due dates, and keeping lecture notes that later become PDF study sheets for revision. A group project team can draft a document together and split tasks between members. When a concept does not click, a student can ask the AI tutor to explain it and return to the chat history later. Notes shared with classmates also help a study circle pool what each person captured in a lecture.
