BBnotes is an AI notebook for international students studying in a second language. Follow lectures with live bilingual captions, translate PDFs side by side, handwrite with Apple Pencil and ask an AI tutor about the exact passage, formula or note on the page—all in one study workspace. FOLLOW LECTURES IN TWO LANGUAGES • Record a lecture and see bilingual captions as your lecturer speaks, on supported devices. • Review a timestamped bilingual transcript after class. • Jump back to the relevant moment instead of searching the entire recording. SUMMARIZE A WHOLE LECTURE • Turn a full recording into an overview and timestamped key points in one tap. • Tap any key point to replay that moment in the recording and transcript. READ AND TRANSLATE PDFs • View the original text and its translation side by side. • Scroll both versions together to keep the same passage aligned. • Tap an unfamiliar word to save it to your word book with its meaning and source page. ASK AI IN CONTEXT • Circle a passage, formula or handwriting and ask directly from the page. • Work through problems by hand while the AI tutor checks each step and hints at the next one. • Keep each question and explanation connected to the source material. WRITE, ORGANIZE AND REVIEW • Take handwritten notes with Apple Pencil on iPad. • Generate an outline to navigate long documents. • Bring reading, writing, translation, lecture audio and AI support into one notebook, synced across iPhone, iPad and Mac. BUILT AROUND THE STUDY DAY Use BBnotes before class to prepare, during class to follow along, and after class to return to what was said and where it appeared in your notes. Download BBnotes for free. New users get a 14-day Pro trial. Optional Pro plans and AI point packs are available as in-app purchases. Pricing is determined by your local App Store. Available on iPhone, iPad and Mac. Live captions require iOS/iPadOS 26. Some features require compatible devices and system versions, and feature availability may vary by platform.
