Oriora Study
Read full descriptionHide full description
Oriora Study turns your own material into study notes, layered explanations, and a week-by-week plan — then quizzes you on it. • Record the lecture — your device transcribes it as the class happens (no audio ever reaches Oriora), and Digest turns the transcript into notes. • Import a PDF — slides or a handout are read on your device; the file is never uploaded. • Photograph a textbook page or your handwritten notes. The page is read on your device, so the photo never leaves your phone. Add several pages to one material; they stay attached, and you can see them. • Digest turns your material into key concepts, a summary, and self-check questions. • Quiz me runs those questions as active recall — answer from memory, then reveal. No AI call, no cost. • Explain teaches one concept properly: an analogy, a precise definition, a worked example, and the mistake people usually make. Photograph the thing you don't understand if it's easier than typing it. • Plan builds the weeks between now and your deadline, with spaced review. • Highlight the concepts that matter, and tap "Go deeper" on any of them. • Talk to it instead of tapping: make notes, build a plan, log study time, search your library, back everything up — from the chat, or in a live call where you just say it and it does the work. It can keep a written plan or summary in a folder in your own GitHub or Google Drive, and go back later to find or tidy them. It teaches; it does not do your work. It will explain how to write a thesis statement, structure an argument, or fix an unclear paragraph you wrote — it will not write, rewrite or finish an essay, assignment or exam answer for you. You are always the author. When it tells you something it didn't get from your own material, it says so, and says it may be wrong. It never invents a citation. Your data stays yours — we don't retain it: data passes through Oriora for each AI action and isn't kept by us. You choose where it lives — this device, and optionally your own GitHub or Google Drive. AI runs on Oriora and is billed to your Oriora wallet.
