AITranscribe vs 讯飞智作：怎么选？

AITranscribe is an online speech-to-text tool for video and audio. You upload a recording (MP4, MOV, M4A, MP3, WAV or WebM, up to about 30 minutes), or paste a public Facebook, Instagram or X video link to try automatic fetching, and the tool turns the spoken dialogue into a timestamped transcript. It works from the audio track, so the video doesn't need existing captions. You can choose between two engines: Whisper running inside your browser, where the file isn't uploaded, or Whisper on Cloudflare Workers AI for faster cloud processing. Results can be copied or downloaded as plain text (TXT), SubRip (SRT) or WebVTT (VTT) subtitles for editors such as CapCut and Premiere. Speech can also be translated (Meta M2M100). The site says it does not store uploaded media or transcripts. A free tier is available after sign-in, with paid Pro and Unlimited plans. (≈145 words)
