What SoCaptions is

SoCaptions is a web-based AI caption generator for short videos. Upload MP4, MOV or WebM files up to 5 GB, then receive word-level captions with Whisper auto-detecting 99 languages. You can edit text, apply styles such as Bold Outline, Box, Cinematic and Karaoke, and burn captions into videos. The service offers watermark-free MP4 output at source resolution plus SRT or VTT downloads, although its subtitle-export listing specifies SRT. It is presented for TikTok, Reels, Shorts and YouTube workflows. The Free plan costs nothing and provides five transcription minutes with editing but no MP4 export. Pro is listed at $3 a month, billed monthly, with 100 transcription minutes and unlimited MP4 exports. Uploaded videos are stored in Cloudflare R2, rendered files are deleted after two days, and SoCaptions says it does not train AI models on user videos or transcripts.
