The Best AI Subtitle Generators in 2026

Start with where the subtitles are going. If you need a proper subtitle file (SRT or VTT), possibly in several languages, plus burned-in captions from the same editor, BlaBlaScribe is our pick overall: 120+ languages, translation into 50+ and 30 free minutes. For styled captions on short TikTok and Reels clips, CapCut (free) and Submagic are quicker. When the subtitles are part of a bigger edit, VEED, Kapwing and Descript make more sense, and for subtitle files proofread by a person there is Happy Scribe.

We make BlaBlaScribe, which is why it’s on the list. Everything else was checked against the vendor’s own pricing and feature pages in October 2026, and we note where another tool does the job better.

AI subtitle generators at a glance

How we compared them

• Accuracy and timing. A line should appear when the words are spoken and break where a reader expects it to.

• Editing. Fixing a name or a line break should take seconds, on a timeline you can actually see.

• What you get out. A clean SRT or VTT file, and captions burned into the video for social platforms.

• Languages and translation. How many languages it subtitles, and whether translated lines keep their timing.

• What the free tier really allows. Watermarks, length caps, and which exports are locked.

The 9 best AI subtitle generators

1. BlaBlaScribe: subtitle files and translation

BlaBlaScribe turns speech into timed subtitles in 120+ languages. You fix lines on a waveform timeline and export SRT or VTT. The same subtitles can be translated into 50+ languages with their timing intact, and you can burn them into an MP4 in one of six caption styles; the video is rendered in your browser. It takes files up to 8 GB, or a YouTube link.

• Free: 30 minutes once, no card. Free MP4 exports cover the first 90 seconds and carry a small watermark.

• Paid: Creator, $14/mo for 600 minutes ($11 yearly), with translation and full-length burned-in video.

• Just want the file? The SRT generator goes straight from video to SRT.

It isn’t the right tool for short vertical clips with animated, emoji-heavy captions (CapCut, Submagic), or if you want cuts, b-roll and music in the same place (VEED, Kapwing, Descript).

2. VEED: a browser video editor with subtitles

VEED is a complete online video editor with auto subtitles, styling, translation on the Pro plan and AI dubbing. Paid plans come with unlimited auto subtitles within a fair-use limit, starting with Creator at $20 a month.

Downloading SRT and VTT requires a paid plan, which matters if the file is all you’re after.

3. CapCut: free captions for short social clips

CapCut’s auto captions cost nothing and come with a huge library of caption styles, inside a full editor for TikTok, Reels and Shorts. Captions can also be translated.

Subtitle files are its weak spot. The desktop and mobile apps export SRT or TXT but not VTT, and CapCut doesn’t publish which languages its captions support.

4. Submagic: animated captions for vertical video

Submagic is made for viral-style shorts: animated captions, emojis, highlighted keywords, and caption translation on every plan. Pricing is per video, and Starter covers 15 videos a month, each up to two minutes.

Once your videos run past a few minutes, or you need a transcript as well as captions, it stops fitting.

5. Kapwing: good value for teams editing together

Kapwing is an online editor built for collaboration. Pro costs $24 a month ($16 yearly) and includes 1,000 subtitle minutes and 500 translation minutes. On the free plan you can subtitle up to 10 minutes and export at 720p, with a watermark.

6. Happy Scribe: subtitle files checked by people

Happy Scribe handles 150+ languages, translates into 80+ and can have a person proofread the result. The Pro plan exports to Premiere, Final Cut and Avid.

There is no free plan, just a 10-minute trial, and Basic includes 120 minutes.

7. Descript: when subtitles are part of the edit

If you already cut podcasts and videos by editing the transcript, Descript adds captions in 61 languages to the same project. As a pure subtitle tool it’s overkill.

8. Maestra: one plan for subtitles and voice-over

Maestra puts transcription, subtitles in 125+ languages and AI voice-over into minute-based plans. Basic is $49 a month ($39 yearly) for 360 subtitle minutes and 180 translated minutes.

9. YouTube Studio: free, if the video is on YouTube

YouTube writes automatic captions for anything you upload, and you can edit and download them in Studio. They’re good enough to follow along with, not always good enough to publish, as we found when we checked how accurate YouTube auto-captions are.

Which subtitle generator should you use?

Burned-in captions or a subtitle file?

A subtitle file (SRT or VTT) stays separate from the video. Viewers can switch it off, YouTube and course platforms can index it, and you can correct it later. Burned-in captions are part of the picture, so they show up everywhere, including social feeds where video autoplays on mute. Most creators end up needing both, which is why tools that make both from one transcript save the most time. More on this in open vs closed captions and SRT vs VTT.

Frequently asked questions

What is the best free subtitle generator?

For short social clips, CapCut’s auto captions are free. For a subtitle file from a longer video, BlaBlaScribe gives you 30 minutes once with no card, and YouTube Studio will caption videos you’ve already uploaded.

Which subtitle generator exports SRT files?

BlaBlaScribe, VEED, Kapwing, Happy Scribe, Descript and Submagic all export SRT, and CapCut does from its desktop and mobile apps. Several of them only let you download files on a paid plan, so check that before you subtitle a long video.

Can AI translate subtitles too?

Yes. BlaBlaScribe translates into 50+ languages and Happy Scribe into 80+, and both keep each line’s timing. Translated lines tend to be longer than the original, which we get into in why translated subtitles break timing.

How accurate are AI subtitles?

On clear audio, very: BlaBlaScribe gets up to 99.8%. Before you publish, check names, jargon and any spots where people talk over each other.
