GOOD TO KNOW
Before you press play
A few things worth knowing about local transcription.
Is CaptionLeaf really free?
Yes. This version has no accounts, payments or transcription credits. It uses your device to process recordings, with an initial limit of 50 MB and 5 minutes.
Does my recording leave my device?
No. Your file is read in this browser and the transcript stays here. The site and speech model are downloaded over the internet; your recording isn't uploaded for transcription.
Which languages can I transcribe?
This version is designed for English speech. You can switch the interface between English and Chinese, but that does not translate the recording or change its recognition language.
What can I download?
TXT is plain text for your notes. SRT contains your edited text with subtitle timing for a video editor or compatible player. Downloading SRT does not add subtitles to your video image.
Why can the first run take longer?
Your browser first downloads and prepares a speech model. It can cache that model for later use. Transcription speed depends on your device and recording; keep the tab open until it finishes.
Will every video or browser work?
Support depends on the file's audio codec and your browser. Start with a short recording in a recent desktop Chrome or Edge. If decoding fails, try a WAV or MP3 file. Always review the result.
