There are two ways to put captions on a YouTube Short, and the right tool depends on which you mean. YouTube's own captions are a toggle the viewer can turn off, and as of 18 October 2026 YouTube's help page says they may not be ready when you upload. Burned-in captions are part of the video itself: they show on every device, on mute, and in the first second of the Short, which is where most viewers decide to stay or swipe. This post is about the second kind, and it compares eleven tools that make them.
The short version: CapCut and the Captions app are the phone-first choices; Kapwing, VEED and Canva do it inside a general editor; AutoCaption, Caption X and quso.ai give free burned-in exports with limits; Zubtitle is a paid social-video tool with a watermarked free plan; and CapsAI is the pay-once browser option when you want every word checked before export and you caption in English, Hinglish or an Indian language.
What a Short is, and why it changes the caption job
YouTube's help page (read 18 October 2026) says a Short is a vertical or square video "up to three minutes in length", and that videos "uploaded after October 15, 2024" that meet those rules are categorized as Shorts. Three minutes of 9:16 video at phone size means short lines, large text, and nothing in the bottom fifth of the frame where YouTube draws the title, channel name and buttons. The Shorts subtitle safe zone tool shows the covered areas.
YouTube's own captions on Shorts
YouTube's automatic captions page (18 October 2026) says automatic captions cover long-form videos and Shorts in a long list of languages including Hindi, that "Automatic captions may not be ready at the time that you upload a video", and that because they come from machine learning "the quality of the captions may vary". English also gets expressive captions that mark loud speech and sounds. The add-subtitles page gives three manual routes in YouTube Studio under Subtitles: upload a file, auto-sync a typed transcript, or type while the video plays; it has no Shorts-specific steps and does not describe adding captions from the mobile app.
Two things follow. First, if your captions are late or missing, the YouTube auto captions missing or late post covers why. Second, YouTube's captions are a separate track the viewer can hide, and they do not travel with the file if you also post to Reels or TikTok. Burned-in captions solve both, and you can still upload an SRT to YouTube afterwards for search and accessibility.

The tools, one at a time
CapCut
capcut.com returns HTTP 451 from India, so our CapCut facts are from a proxy render. CapCut's own pages disagree on price. Its auto caption page (read 18 October 2026) calls speech-to-text "free of charge" and shows "multiple languages" with an "American English" language menu, while its help article comparing Standard and Pro, dated 2 April 2026 and read on 19 October 2026, lists auto captions among Pro's "Advanced AI tools". Users report a Pro prompt at export, and Pro is listed at USD 19.99 a month. It is the editor most Shorts creators already use, with 9:16 caption templates and direct export. Watermark policy is not stated on the pages we could render, and some templates are CapCut Pro inside the app, so export a test clip; the CapCut auto captions post has the detail.
Captions app
Captions (captions.ai) says on its homepage (18 October 2026) that it offers "100+ caption styles" in "100+ languages" and that "It's free to sign up for Captions, but you'll want a subscription to access the best features". Its pricing page shows one caption template on Free and a Max plan at $24.99 a month, "iOS plans only". Watermark policy is not stated. See Captions vs CapsAI.
Kapwing
Kapwing's pricing page (18 October 2026): 10 minutes of auto-subtitling, exports up to 4 minutes at 720p, "Unlimited exports with a watermark", 2 GB uploads; Pro shows $16 with the billing period not labeled. The subtitles page confirms SRT, VTT and TXT download and lists creator-style templates. A good fit if you resize a landscape video to 9:16 and caption it in one place. See Kapwing vs CapsAI.
VEED
VEED's tool page (18 October 2026) says it is "free to start", that you "Upgrade to a paid plan to subtitle longer videos and download subtitle files", and that "A Creator plan starts at $20/month", with 125+ languages claimed and no watermark statement. Treat it as a subscription editor.
Canva
Canva's caption pages refused our fetch (HTTP 403) on 18 October 2026. Google's listing text of those pages says the free tier has "unlimited usage of captions with color, stylings and animations" and the help page lists about 80 languages; translation shows as "Translate (Pro)" on one page and free on another. Watermark, length cap and SRT are not stated in anything we could read.
AutoCaption
AutoCaption's pricing page (18 October 2026) lists Starter at $18, Expert at $25 and Pro at $39 a month, capped at 2, 3 and 6 minutes per video, each marked "No watermark", with Full HD exports on the lower plans and 4K on Pro. Its tool pages say there is a free plan with no card and 100+ languages, and that captions are burned in at 9:16; the free tier's limits and watermark rule are not stated.
Caption X
Caption X's studio (18 October 2026) takes videos "up to 10 min" and "under 2 GB", offers "unlimited free exports", and says "Free exports carry a small CaptionX watermark (Pro removes it); the SRT subtitle file is always watermark-free". It claims 100+ languages. Useful if you want a free SRT for YouTube Studio alongside a burned-in test.
quso.ai
quso.ai ranks for "add captions to youtube shorts". Its caption tool page (18 October 2026) names YouTube Shorts, Reels and TikTok as targets, claims "more than 100+ languages", and says you can "Export in SRT" or burn the captions in. Its pricing page shows a Free plan at $0 with "75 credits / month" where "One credit ≈ one minute of processed video" and "720p render quality", then Lite at $29, Essential at $39 and Growth at $49 a month with 1080p. There is no watermark statement on either page.
Zubtitle
Zubtitle's pricing page (18 October 2026) is explicit: Bootstrapper at $0 gives two videos a month, up to 720p, 20-minute uploads and "Zubtitle watermark added"; Guru at $19 a month gives ten videos at up to 4K with "Watermark removed"; Agency at $49 gives thirty. Uploads must be MP4, MOV or M4V under 1 GB and 20 minutes or less, and "a .txt or .srt file can be downloaded" for each video. It has a YouTube Shorts page and resizes landscape footage. The FAQ describes the trial as one video while the plan card says two, so expect one or the other.
CapsAI
CapsAI runs in a phone or desktop browser. Upload an MP4 or MOV up to 10 minutes (a Short is at most three), pick the spoken language from English, Hinglish in Roman script, Hindi, Bengali, Telugu, Marathi, Tamil, Urdu, Gujarati, Kannada or Punjabi, correct the draft word by word, choose one of 37 styles, and export one MP4 with the captions burned in at 1080p on Starter or up to 4K on Creator and Pro. It does not export SRT, does not translate, and does not import from a YouTube link; download the Short first. New accounts get 3 free minutes; packs are paid once from $4 (₹49 in India, €4 in the euro area) for 20 minutes, and watermark-free export comes with every paid pack. The YouTube Shorts subtitle generator is the starting point.
Best for each situation
- You cut Shorts from long videos: Kapwing or VEED for resize plus captions in one editor; on CapsAI, use Smart Clips to cut the highlights first, then caption the clip; the long video to short video page explains that route.
- You want a free SRT for YouTube Studio as well: Caption X or quso.ai export one; Clipchamp does too if you also edit on Windows.
- You caption in Hinglish or an Indian language: CapsAI is the only tool in this list that names Hinglish as a spoken language.
- You post the same clip to Shorts, Reels and TikTok: burn the captions in with any tool here rather than relying on YouTube's track.
- You want zero cost and accept a watermark: Zubtitle's free plan or Caption X.
Step by step: burned-in captions plus a YouTube caption track
- Caption the clip with one of the tools above and export the MP4. The how to add subtitles to YouTube Shorts post walks through the CapsAI version.
- Upload the MP4 to YouTube as a Short (vertical, under three minutes).
- If you also have an SRT, open YouTube Studio, choose Subtitles, pick the video, click Add Language, then Add, and upload the file. Viewers who need the track get it; everyone else reads the burned-in words.
- Check the Short on a phone. If the caption block sits under the title overlay, move it up and re-export.
What to do next
Upload one Short at the YouTube Shorts subtitle generator, read the draft within the 3 free minutes, and compare it with YouTube's own captions on the same clip. Keep whichever gets your names right. For regular long-form uploads, the YouTube subtitle generator page covers the landscape case.
