Everything you're wondering.

Harbor is an exam readiness system for your exact class. You add your course materials, and Harbor tells you where you stand and the single best thing to study next — an honest answer to one question: are you ready?

Harbor breaks your course into small, testable elements and marks each one solid, uncertain, or weak, weighted by how much it tends to move your grade. Together they form your Readiness Map — one live percentage plus a clear view of what's strong and what still needs work.

It reads your exact materials — your section, your professor's emphasis, your exam timing — rather than a generic version of the subject. Each element is weighted by likely impact, so your effort goes to what actually counts on this exam.

Generic AI answers anything but knows nothing about where you stand. Flashcard apps still make you decide what belongs in the deck, then drill everything equally. Harbor diagnoses: it measures your readiness and points you at the one move that matters most, grounded in your own material.

Permitted study material only: your own notes, professor-provided slides and syllabi, review guides, and past exams your instructor has released. Don't upload anything under a confidentiality or honor-code restriction, or content you don't have the rights to use.

No. Harbor helps you prepare before graded moments — it maps material, measures readiness, and explains concepts so you learn them yourself. It won't complete assignments, generate work you'd submit, or help during a closed exam. Your course and school policies always come first. See our Academic Integrity page.

No. Harbor helps you understand what matters — you still learn the material, answer the questions, and decide what you know. It won't generate work you'd submit as your own.

No. Harbor is for preparation before the test. Don't use Harbor during exams, quizzes, or restricted assignments.
