About this app

Turn any video into accurate subtitles, a translated version, or a fully dubbed one — automatically. SubFlow AI transcribes the speech, translates it into 99+ languages, and can re-voice your video with an AI voice you choose.

YOUR VIDEO NEVER LEAVES YOUR PHONE
SubFlow AI extracts only the audio on your device and uploads just that — a few megabytes instead of a few gigabytes. The video itself stays with you, and burning the subtitles into it happens locally on your phone.

WHAT YOU CAN DO
• Auto subtitles: speech recognition turns any video into timed captions, no typing
• Translate video: subtitles in 99+ languages, with a glossary so names and terms stay consistent
• AI dubbing: replace the original audio with a natural AI voice in 85 languages, Persian included. Choose the voice, preview it, then export
• Subtitle editor: fix any line, nudge the timing, merge or split
• Quality review: SubFlow flags missing translations, overlapping lines and bad timing, and can fix them in one tap
• Export your way: SRT subtitle file, burned-in MP4 video, both, or a dubbed video
• Styling and presets: colour, size, position, outline, plus ready-made looks sized for YouTube and TikTok
• Trim a long video down to the part you actually need, right inside the app

LONG VIDEOS WELCOME
Lectures, podcasts, sermons, interviews and full films — up to 3 hours per video. Without a subscription you can subtitle a 15-minute video, and a one-off minute pack lifts that to 60 minutes.

SIMPLE, HONEST PRICING
• Minutes, not credits: one minute of video costs one minute
• A job that fails never consumes your quota
• No subscription required: buy a minute pack when you need one, and those minutes do not expire when the month resets
• Remove the watermark once and it stays removed

PLANS
Free: 30 minutes per 30 days, videos up to 15 minutes, every core feature, watermark on exported video
Basic: 200 minutes, videos up to 60 minutes, no watermark
Pro: 1000 minutes, videos up to 3 hours, AI dubbing with voice selection, compact H.265 export

BUILT FOR EVERY LANGUAGE
Transcription and translation cover Persian, Arabic, Hindi, Urdu, Indonesian, Vietnamese, Spanish, Portuguese, Turkish, Russian, Chinese, English and 88 more — right-to-left scripts included. The app itself is translated into 145 languages and runs well on affordable phones and slow connections.

WHO USES SUBFLOW AI
Creators adding captions to short vertical video. Teachers captioning lectures and course material. Translators who just need a clean SRT file. Podcasters turning speech into text. Anyone who wants an audience that does not share their language to understand the video anyway.

HOW IT WORKS
1. Pick a video from your phone
2. SubFlow transcribes the speech and translates it
3. Review and edit the subtitles, or let the quality check fix them
4. Export an SRT file, a subtitled video, or a dubbed one

AI transparency: subtitles, translations and dubbed voices in this app are generated by AI and can contain mistakes. Review them before you publish.
