Free YouTube to Thread Converter
Turn a YouTube video into an X or Threads thread by pasting its link. We read the captions and use AI on our servers to write a connected draft around the video's key points. The first post is free to preview here; create a free account to see the full thread. You do not need to supply an AI API key. If the video has no captions we can read, paste the transcript instead. This converter writes a thread from the material you provide; it is not a transcript downloader. Use a video you own, or credit the original creator and source when sharing their ideas. Read the draft before using it, checking names, numbers, and any context that a short post might lose. You can then refine the opening and transitions to match your voice. ThreadMaster publishes to X, Threads and Facebook Pages.
