Best AI Captions

Best AI Captions transcribes speech in a video and burns styled captions onto it, or turns audio and video into SRT, VTT, TXT and Word files. It is free, needs no account and adds no watermark, which suits people making TikToks, Reels, Shorts and lesson videos.

After uploading a file of up to 4 GB in formats like MP4, MOV, WebM, MP3, WAV or FLAC, you choose a caption look such as Viral, Native, Clean or Punchy, or build your own by changing font, color, highlight, border, background box, size and position. A short preview shows real captions on a sample before the full video is rendered.

The Transcribe option skips burning and gives subtitle and text files instead. The site comes from Mallary Labs, which also lists separate translate and dub tools.
