What you can do with an extracted transcript
Repurposing is the obvious win: one talking video becomes a newsletter section, a carousel, a thread, or a blog post, and search engines can read text where they cannot watch video. Transcripts also make translation cheap, and they are the right input for AI tools that summarize or rewrite content.
Captions are usually the easiest transcript source you already have. If a platform generated subtitles for your video, downloading that file and running it through this tool is faster than re-transcribing the audio.
Getting a transcript when you have no subtitle file
If all you have is the video, you need transcription first. Most cloud tools charge per minute and require uploading your footage. On iPhone, Wavcut transcribes on-device, the audio never leaves your phone, and uses that same transcript to burn captions, cut silences, and place b-roll automatically.
Whichever route you take, keep the transcript. It is the most reusable asset a video produces, and the raw material for every repurposing workflow.
