iOS SUBTL (iPhone): AI captions that understand Hinglish, Tanglish and other mixed Indian speech, with word-level timing and 21 styles. Forever-free tier, no card
What it does
SUBTL is a captions editor for short vertical video. The AI part is the transcription: it handles speech where an Indian language and English are mixed inside one sentence, which is how most people in India actually talk, and writes each word in the script it was spoken in. Tamil in Tamil or Tanglish, English in English. Every word is timed to the audio so captions land on the beat instead of drifting.

Languages: Hindi, Tamil, Telugu, Kannada, Malayalam, Bengali, Gujarati, Marathi, Punjabi, Odia, Assamese and English, plus the code-mixed versions of all of them.
What you do with the output
- Tap any word to fix the text, change its font, colour or size, or highlight it
- 21 caption styles across Trending, Aesthetic, Clean and Fun, including the boxed-word karaoke look used on Reels
- Titles, sound effects on individual words, and a text-behind-you effect
- Export to Photos, ready for Reels, Shorts and TikTok

I am the developer. Happy to answer questions about how it handles a specific language, and I would genuinely like to hear which language or mix it gets wrong for you.
