About Flowsub

FlowSub turns an uploaded video or audio file into subtitles. You drop in a file of any common format up to 500 MB, the AI transcribes it with automatic language detection across more than 29 languages, and you download SRT, VTT, ASS or TXT files that work with any editor. The process is described as taking about two minutes for a 10-minute video, and no signup is needed to try it.

Subtitles can be translated into 29 or more languages, edited inline for timing and text, and burned into the video as an MP4 export. The site markets it to YouTubers adding captions, podcasters making transcripts and SRT clips, and course creators translating lessons. Transcription runs on a hosted Whisper model, and the navigation also lists related tools for image, video, voice and music generation and file conversion. The free plan includes 5 credits a month with all features and no watermark. A Pro plan costs $4.99 a month for 100 credits, with a 14-day money-back guarantee and cancellation at any time.
