Studying in a country where you don't fully speak the language is hard enough. When your professor records a 90-minute lecture in German, Japanese, Korean, or Spanish, the last thing you need is 30 minutes of dead air making it even longer.
5cut is an iPhone app built for exactly this situation.
When you're following a lecture in a second language, every minute of attention costs more effort. You're translating in your head, re-listening to phrases, and trying to keep up with unfamiliar vocabulary. Silence between slides or during transitions doesn't give you a rest — it breaks your concentration.
Removing that silence means you spend less total time per lecture, and the remaining content flows without interruption.
Automatically detects and cuts pauses, transitions, and dead air. A 90-minute lecture typically becomes 55–65 minutes. Use Smart Mode presets or fine-tune the threshold yourself.
Generate subtitles for your lectures in the original language. Burn them into the video or export as SRT. Everything happens on your device — no uploads, no privacy concerns. Supported languages include German, Japanese, Korean, Chinese, Spanish, French, Italian, Portuguese, Vietnamese, and many more.
Seminars and group discussions with multiple speakers? 5cut identifies up to 4 speakers automatically, color-coded and renamable. Know exactly who said what.
Don't process lectures one by one. Queue up an entire semester and let 5cut handle them all in the background with the same or individual settings.
5cut supports transcription in 30+ languages, making it useful wherever you study:
The 5cut interface is localized in English, German, Spanish, French, Italian, Japanese, Korean, Portuguese (Brazil), Vietnamese, and Simplified Chinese. The app automatically matches your iPhone's language.
5cut is free with 10 exports per month. All processing is on-device — your recordings never leave your phone. Premium ($1.99/month or $6.99 lifetime) adds unlimited exports and batch processing.
