BBnotes vs PDF Beacon

BBnotes is an AI notebook for international students studying in a second language. Translate PDFs side by side, follow lectures with bilingual captions, handwrite with Apple Pencil and ask an AI tutor about the exact passage, formula or note on the page—all in one study workspace. READ AND TRANSLATE PDFs • View the original text and its translation side by side. • Scroll both versions together to keep the same passage aligned. • Keep the source visible while you highlight, annotate and handwrite. FOLLOW LECTURES IN TWO LANGUAGES • Record a lecture and see bilingual captions on supported devices. • Review a timestamped bilingual transcript after class. • Jump back to the relevant moment instead of searching the entire recording. ASK AI IN CONTEXT • Circle a passage, formula or handwriting and ask directly from the page. • Keep each question and explanation connected to the source material. • Get guided explanations and next-step prompts when working through a problem. WRITE, ORGANISE AND REVIEW • Take handwritten notes with Apple Pencil on iPad. • Generate an outline to navigate long documents. • Keep important explanations beside the material they refer to. • Bring reading, writing, translation, lecture audio and AI support into one notebook.
