Frequently asked questions
Subtightl is a mobile app that adds designed, animated captions to short videos and burns them in. New users get 3 free minutes; there are no ads and no forced watermark.
What is Subtightl?
A mobile app that adds designed, animated captions to short videos and burns them into the video. It transcribes the speech automatically, lets you fix any word, and exports a captioned video ready for Reels, TikTok and Shorts.
What caption styles are there?
Six complete looks, each designed for a kind of creator: Punch (coaches, fitness, founders), Clean (educators, podcasts), Soft (storytelling, beauty), Bounce (streamers, gaming, comedy), Lyric (music) and Elegant (fashion, aesthetic). Each has its own type treatment, way of revealing words, how — or whether — it marks the spoken word, and motion. See them on real videos.
How much does it cost?
New users get 3 free minutes. Minute packs cost $0.99 (1 minute), $3.99 (5), $6.99 (10) or $14.99 (25); Pro is $7.99 a month with no minute counter (fair use applies). US prices — the store shows yours in local currency. Pricing details.
How are minutes counted?
By the second of video, never rounded up to a whole minute. English captions for a clip in another language cost an extra half of its length — a 60-second clip uses 60 + 30 seconds. Editing, re-styling and exporting again are free, and minutes for a failed transcription are refunded automatically.
Are there ads or a watermark?
No ads in the app. Exports carry no watermark unless you turn one on in Settings — on every plan, including the free minutes.
Is it on iPhone?
Subtightl is on Android (Google Play) now. The iPhone version is coming soon.
Which languages does it support?
Captions in English, Spanish, Portuguese, French, German, Italian, Japanese, Korean, Chinese and Russian. Japanese, Korean and Chinese are set in Noto typefaces made for those scripts; serif styles stay serif.
Can I get English captions on a video in another language?
Yes. Choose English captions and Subtightl writes them from the original speech — or show both lines, the original and English, at once.
Can I edit the captions?
Yes. Tap a line to correct its words. Your project is saved, so you can come back, change the style and export again without transcribing twice.
Does it burn the captions into the video?
Yes. The export is a new video with the captions drawn into the picture at your video's resolution, so they show on every app exactly as designed. See open vs closed captions.
Is my video uploaded?
Only the audio is sent for transcription. The video stays on your phone, and the captions are drawn into it there.
Do I need an account?
No account is needed to try it with the free minutes. Buying minutes requires signing in, so your balance follows you to a new phone. You can have your account and its data deleted at any time — here is how.
How is it different from CapCut or Submagic?
Subtightl does one job — captions — and focuses on how they look: six designed styles instead of a long template list, captions that follow every word, paid by the minute, with Pro optional. CapCut is a full video editor; Submagic is a captioning tool with many templates, sold monthly or yearly. See vs CapCut and vs Submagic.
