About

Qubase

Read full description

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. KEY FEATURES: Intelligent Parsing: ============= - AI worksheet parsing: Convert PDF worksheets into structured question data, including question text, answer keys, and multiple-choice options. - Smart handling of complex content: Parse challenging layouts, convert equations to TeX, and transform tables into clean Markdown-style structure. - Handwriting and scanned-note support: Extract text from handwritten or scanned worksheet content (results may vary by source quality). Similarity Tracking: ============== - Similar-question detection: Find related questions across your library and compare them side by side. - Repetition and similarity tracking: Identify duplicate questions with similarity scores, so you can reduce repeats and maintain question variety over time. Pricing: ====== - Pay-as-you-go model: Start with free credits, then purchase more only when needed. Credits do not expire. - Credit transparency: AI processing uses credits only when importing worksheets; editing, searching, reviewing, and sharing remain free. Continuity: ======== - Portable question libraries: Save your database as a shareable file that colleagues can open and edit in Qubase for free. - Seamless on Apple devices: Use Qubase on iPhone, iPad, and Mac, with support for side-by-side, multi-window workflows on larger screens.
