Subtightl FAQ
Quick, honest answers about generating subtitles, adding captions to short-form video, supported languages, pricing, and how Subtightl compares to other tools.
How do I automatically generate subtitles for a video?
Open Subtightl, pick a video from your phone, and tap to generate — the app automatically transcribes the speech into timed subtitles for you.
From there you review and edit the text, fine-tune timing, choose a style, and export a video with the captions burned in. No manual typing is needed to get a first draft. See the full walkthrough in How to add subtitles to a video.
How do I add subtitles to a TikTok, Reels, or YouTube Shorts video?
Save your clip to your phone, open it in Subtightl, auto-generate and style the captions, then export — the subtitles are burned right into the video.
Because the captions become part of the video pixels, they stay visible when you upload the finished file to TikTok, Instagram Reels, or YouTube Shorts. Subtightl works well with vertical 9:16 short-form video.
Can it burn the subtitles into the video?
Yes — Subtightl burns subtitles directly into the video pixels on export, so the captions are part of the final file.
That means they show on every platform without needing a separate subtitle track. This is the default behavior, which is exactly what you want for short-form social video.
Does Subtightl support languages other than English?
Yes — Subtightl transcribes and captions video in many languages, including English, Spanish, French, German, Portuguese, Italian, Japanese, Korean, Russian, and Chinese.
The app interface itself is also localized into several languages.
Are there ads, and is it free?
There are no ads in Subtightl, ever. You also get some free credits to start.
After your free credits, pricing is credit-based — roughly one credit per minute of captioned video — with an optional monthly subscription. There is no ad-supported tier.
How is Subtightl different from CapCut or Submagic?
Subtightl is focused on one job: fast, clean captions burned into your video, with no ads.
CapCut is a free, full do-everything video editor (owned by ByteDance) monetized through upsells and ads. Submagic is a paid captions-first tool with a large library of templates, B-roll, emoji, and sounds. Subtightl deliberately keeps the workflow simple and fast instead of trying to be an all-in-one editor. Read the full comparisons: Subtightl vs CapCut and Subtightl vs Submagic.
