Record the lecture, not the room
Apple's voice isolation keeps the lecturer's voice and quiets the room — noise, hiss, and echo. You can turn it off, or adjust the mix during the recording. Recording continues while the phone is locked.
Lektu
Every lecture, transcribed
Record a lecture on iPhone. Transcription runs on your iPhone, in the language of the class. Audio stays on the phone.
Transcription on the iPhone
More than 20 languages, including English, Arabic, Spanish, French, German, Chinese, and Japanese. The speech model is downloaded once over Wi-Fi, about 452 MB, so transcription can run on the phone.
Speakers separated on the phone
A local model marks who spoke when. Rename Speaker 1 to Professor, or any other name. Each speaker keeps a colour.
Private by design
Recordings and transcripts stay on the iPhone. Speech recognition, speaker separation, and Hebrew repair run on the phone. Lektu does not collect audio and does not track you. Summaries are optional. Transcript text is sent to Google Gemini only when you tap Summarize or ask a question. Skipping that sends nothing.
Read and share
Lectures live in folders. Search is on the phone. Share a transcript as text, Markdown, or subtitles, or send the recording.
