FROM RECORDING TO RESULT
Transcripts and subtitles for your next step
MP4 to text for video recordings
Turn the English speech in a local MP4 into an editable transcript. Copy passages into your notes or download a TXT file. MP4 with H.264 video and AAC audio has been tested; other encodings depend on your browser.
MP3 to SRT for timed subtitles
Transcribe an MP3 or WAV recording, correct the words, then download SRT with timestamps for a compatible editor or player. Review subtitle timing before using it. This creates a subtitle file, not a new video with captions burned in.
Instagram transcripts from public videos
Switch to Instagram / Reels and paste a single public video link. Import is in beta: private posts, Stories, carousels and live video are not supported, and some public links may fail. You can use a local copy you have permission to process.
GOOD TO KNOW
Audio & video transcription FAQ
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?
Local files are not uploaded. For Instagram imports, CaptionLeaf receives the video link and fetches the media through its server. Speech recognition and the transcript stay in your browser. The site and speech model also require network downloads.
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 audio codec and browser. Instagram import is in beta and supports accessible, single public video posts and Reels. Private content, carousels, Stories and live video are not supported. Instagram can block requests. Start with a short recording in a recent desktop Chrome or Edge and review the result.
