What SubFlow AI is
SubFlow AI brings video transcription, translation, subtitle editing, and export into one workspace. It uses Whisper speech recognition and contextual translation to create a synced bilingual draft, which users can refine by changing wording, splitting or merging captions, and keeping translations aligned with the original timing. The service supports more than 99 target languages and accepts MP4, MOV, MKV, and WebM uploads. Captions can be styled, exported as SRT or VTT, or rendered into a video. Paid plans provide watermark-free Full HD video export. The Free plan includes 30 processing minutes monthly and allows videos up to 15 minutes; Basic costs $2.99 a month for 200 minutes and videos up to 60 minutes. Pro costs $9.99 a month and includes 1,000 minutes, videos up to 180 minutes, and AI voiceover dubbing. SubFlow AI is available on the web and Android, with the web workspace intended for detailed editing on larger screens. Projects are private to the account, and users can delete project media and account data.
