免費 · App內購買

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. 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. Some features require compatible devices and system versions, and feature availability may vary by platform.

Redesigned live-caption sentence segmentation to combine fragmented recognition results into natural sentences, with support for CJK text and multiple sentence-ending punctuation marks. Trailing text is also committed after approximately 1.5 seconds of silence. Reduced growing caption latency by prioritizing the latest audio data when the device is under load and using more accuracy-focused final transcription results. Fixed an issue where cancelling an earlier recording task could incorrectly deactivate the microphone session of a newer recording. Improved handwriting responsiveness by avoiding caption-anchor tasks for every PencilKit callback within a single stroke. The final handwriting anchor is now preserved when recording is paused or stopped. Added ordering safeguards for translation persistence and cloud sync, preventing cases where translations were saved locally but missing on other devices. Redesigned the caption bar with a more compact single-line layout while maintaining support for accessibility text sizes. Fixed issues where translation-download prompts could appear repeatedly, reopen automatically after cancellation, or allow outdated translation results to be written back after leaving a document. Reduced redundant page-state updates and drawing-toolbar switches while scrolling PDFs, improving scrolling and handwriting performance. Fixed recording deletion confirmation messages that did not include the recording filename in some languages. Restored CoreAudio compatibility for Mac Catalyst. Made backend refund processing atomic and idempotent, preventing duplicate AI-point deductions, retained Pro access after refunds, and inaccurate restoration after refund reversals. Removed the document-conversion server prewarming request from app startup.
