Keep up in the moment
Read the original speech and translation while the lecturer continues.
Live lecture translation
Follow lectures with live bilingual captions.
See the lecturer’s words translated while you listen. After class, return to the recording and review it as a timestamped bilingual transcript — without separating it from your notes. On-device captions require iOS/iPadOS 26 and a supported device. Cloud captions require internet access and available preview or Premium translation time.

Return to what you missed
Use timestamps to revisit the relevant part of the recording.
Keep notes connected
Lecture audio, transcript, and your notes stay in one workspace.
Two processing modes
Choose on-device or cloud processing for your lecture.
Both modes keep captions, transcripts, and recordings with your notes. Choose your mode before recording.
On-device transcription & translation
Speech recognition and translation run on your device. Once supported speech and translation language packs are downloaded, you can use this mode offline without sending audio to a cloud transcription service.
Requires Pro access, iOS/iPadOS 26, and supported hardware. Language availability depends on your device and downloaded packs.
Precision cloud transcription & translation
Transcribe and translate online with automatic spoken-language detection. With AI Data Sharing enabled, audio is streamed to Soniox for processing.
Requires sign-in and available free preview or Premium translation time. No on-device speech packs are needed; check the app for available languages and your balance.
Built for second-language lectures
Listen now. Revisit the exact moment later.
Live translation helps you follow the room; timestamps make the recording useful after class.
01 · Start
Open your course note and begin the lecture recording.
BBNotes keeps the listening workflow inside the notebook you already use for the class, rather than starting a separate recording and translation trail.
02 · Follow
Read the lecturer’s words and translation together.
Keep listening while the original speech and translated captions stay visible. You do not have to leave the lecture to rebuild one sentence in another app.
03 · Review
Tap a note or transcript line to return to the recording.
Find the sentence you missed, replay the corresponding moment, and review it beside the course material instead of searching through an undifferentiated recording.
One continuous lecture record
From spoken sentence to reviewable course context.
BBNotes keeps the live moment and the later review connected.
