Qubase is built for professional educators who want to organize their worksheet collections. It instantly turns your worksheets into a question database.
Instead of manually retyping, sorting, and tracking content across folders, you can import PDFs and let Qubase’s AI parse them automatically into a searchable question bank that is easy to organize, compare, and reuse.
Qubase allows you to track how often a question, or a similar one, has appeared over time. Whether you are preparing revision materials, internal tests, or year-level exam sets, it helps you quickly find what you already have, identify overlap, and decide what to update.
Qubase's AI parser intelligently handles complex PDF structures and academic content, including mathematical equations, chemical formulas, multiple-choice questions, and table-heavy layouts, and more.
Your question bank stays portable and shareable, so departments can collaborate without rebuilding resources from scratch. With cross-device support across Apple platforms, Qubase gives educators a clear path from scattered worksheets to a structured, searchable library that grows with their curriculum.
We use Google's Gemini AI to securely parse PDF files you import to the app. Google acts solely as a data processor and does not use this data to train its models.
