Our verdict on SubFlow AI
SubFlow AI is a web and Android video-subtitling tool for creators who need to turn speech into timed captions, translate subtitles, and export finished files or captioned video. Its bilingual editor brings translated and original subtitles together, while styling controls cover colors, size, position, outline, and canvas presets. It fits solo creators and small teams looking for an affordable captioning workflow, particularly when multilingual output matters more than a large editing suite.
The published plans show a free tier with 99+ languages, SRT export, and watermarked video export. Basic costs $2.99 per month and removes the export watermark while adding Full HD video export. Pro costs $9.99 per month and adds AI voiceover dubbing, priority processing, and H.265 export. All prices are monthly USD; the vendor says regional prices may vary and Google Play displays purchase pricing. This tier structure makes it possible to start without paying, though creators who need clean video exports must move to Basic, and those seeking dubbed audio need Pro.
SubFlow accepts video and audio uploads and supports workflows for content from Google Drive, Dropbox, TikTok, and Instagram. Caption timing and text can be edited, and subtitles can be exported as SRT or VTT or burned into the video image. Those options make it suitable for creators repurposing content across languages and social channels. The listed maximum video length is 60, so it may not suit workflows requiring longer source videos. Choose it for economical subtitle translation and direct captioned exports; consider another tool if you need a wider platform range or a workflow centered on longer videos.
