Record and transcribe
Preserve local lecture audio while finalized and in-progress English text appears on screen. Pause, resume, and recover from supported interruptions.
Private by design · On device
Hear it. Read it. Return to the exact moment.
EchoNote Lecture turns an English lecture into a synchronized study timeline—local audio, timed transcript, Simplified Chinese translation, bookmarks, and slide photos—ready whenever you need to review.

The key distinction is not the amount of information, but how quickly you can return to it.
关键不在于信息的数量，而在于你能多快回到需要的内容。
One continuous learning flow
Capture less frantically. Review more precisely.
The original audio and English transcript remain the evidence layer. Translation and Apple Intelligence polishing are optional aids that never overwrite the source.
Understand bilingually
Translate finalized sentences into Simplified Chinese during or after class, then optionally polish the saved translation on supported Apple Intelligence devices.
Replay with context
Follow sentence and word highlighting, tap any sentence to seek, loop a difficult sentence, change playback speed, or jump through bookmarks.
Mark the moments
Add timestamped bookmarks and notes during class. Attach slide or whiteboard photos to the moment they were selected.
Correct without erasing
Add a correction layer to a recognized sentence, retain the original transcript for reference, and retranslate only the corrected sentence.
Organize and export
Filter by course, search the lecture library or full transcript, and share corrected notes as Markdown, timed subtitles as SRT, or the original audio.
Local-first architecture
Your classroom content stays under your control.
EchoNote Lecture has no account system, advertising SDK, analytics SDK, or developer-operated content server. Recordings, transcripts, translations, corrections, bookmarks, playback state, course information, and attached photos are stored in the app’s local container.
Apple speech and language resources may need a one-time system-managed download. Content leaves the app only when you explicitly export or share it.
