Lecture Transcription
ClapClip turns recorded lectures into searchable, quotable notes on your Windows PC. Record the class, drop the file in, and get the full text — free, offline, and without the length limits that make cloud tools useless for 90-minute sessions.
- No length limits — full 2-hour lectures
- Free for a whole semester of classes
- Robust to lecture-hall acoustics
- Searchable notes from every session
Windows 10 & 11
Full lectures, not 30-minute fragments
Lectures run 60–120 minutes, past the free-tier caps of most cloud transcribers. Local processing has no cap: a full semester of recordings transcribes at zero cost.
Search your whole semester
Text transcripts turn a pile of recordings into a searchable knowledge base. Before an exam, search every lecture for a term instead of scrubbing through hours of audio hoping to find the right minute.
Handles lecture-hall audio
Distant microphones, echoing rooms, and technical vocabulary are the norm for lecture recordings. Whisper-class models are robust to exactly these conditions, keeping accuracy usable even from a phone at the back of the hall.
FAQ
Can it transcribe a 2-hour lecture?
Yes. There are no length limits — long recordings simply take proportionally longer to process locally.
Will it understand technical terminology?
Whisper-class models handle domain vocabulary well — scientific terms, names, and jargon transcribe far better than with older engines.
What if I recorded from the back of the room?
The models are robust to distance and echo. Very poor audio reduces accuracy, but typical phone recordings from a lecture hall work well.
