Caption generator

Caption generator — turn any video into captions.

Upload a clip and get accurate, timestamped captions back — even if the video has no captions of its own. We transcribe the audio itself with Whisper Large v3 Turbo, so short-form videos, screen recordings, and raw exports all come out captioned. Download SRT or VTT and drop it into your editor or uploader.

What you get

Captions that boost watch-time.

Upload the clip, get timestamped captions back — no existing subtitle track required. Built for the short-form video that lives or dies on whether people can read it with the sound off.

01
Captions from the audio
We don't need an existing caption track — we transcribe the audio itself. So a raw export, a screen recording, or a clip with no subtitles all come out fully captioned.
02
Real, synced timestamps
Every caption carries a genuine start time pulled from the audio, so the SRT or VTT you download lines up with the video instead of drifting out of sync.
03
On-mute ready
Most feed video plays silently. Clean, punctuated caption text means your message still lands when the sound is off — and stays readable at a glance.
How it works

From clip to captions in three steps.

Choose the video, let us caption it from the audio, then download the caption file. Captioning is a Plus and Pro feature at 10 credits per audio-hour.

01
Upload your video

Drag a video or audio file onto the box above, or click to browse. MP4, MOV, WebM, MP3, M4A and more — up to 500MB and six hours. Sign in on a Plus or Pro plan to start.

02
We caption the audio

Whisper Large v3 Turbo transcribes the audio and splits it into timed caption segments — even when the clip has no captions of its own. Costs 10 credits per audio-hour.

03
Download SRT or VTT

Grab the caption file and drop it into your editor or the platform uploader. Also export TXT and PDF, or translate the captions to 40 languages first.

Beyond captions

More than a caption maker.

Every captioned clip can be translated, summarized, repurposed, or exported — one upload, many directions out.

Multi-language captions
Caption once, then translate the text into 40 languages to caption the same clip for audiences around the world.
AI summaries
A two-sentence recap of the clip plus its core hook — handy for writing the post copy that goes with it.
Repurpose to 8 formats
Spin the captioned transcript into a thread, a description, or a newsletter blurb in your own voice.
Export SRT · VTT · TXT · PDF
Download the caption file your uploader or editor expects, plus plain text and PDF for notes and sign-off.

How it works

How to generate captions for a video.

A caption generator turns spoken words into on-screen text with the timing your video needs. Upload the clip and we transcribe its audio with Whisper Large v3 Turbo, then break it into timed caption segments you can download as SRT or VTT. Captioning is a Plus and Pro feature at 10 credits per audio-hour.

Works even with no existing captions

This is the difference from a caption downloader: we don't read a caption track that already exists — we create captions from the audio. So a raw camera export, a screen recording, a voice-over, or any clip that was never captioned comes back fully captioned. If it has sound, we can caption it.

Why captions lift your reach

Most feed video autoplays on mute, so a clip with no text loses viewers in the first second. Captions keep thumbs still, raise average view duration, and pull in the sound-off majority — which is why creators treat them as a growth lever, not a nice-to-have.

Accessible by default

Captions make your videos usable by deaf and hard-of-hearing viewers and help satisfy ADA and WCAG expectations for accessible media. The same file that boosts your watch-time also opens your content to an audience that would otherwise be shut out.

Caption once, reach every language

After captioning, translate the text into Spanish, French, Mandarin, Arabic, Hindi, and 35 more languages — so a single upload becomes captions for audiences worldwide, all without re-transcribing.

Download the caption file, add it your way

We produce caption files — SRT and VTT — that you load into your video editor or the platform's own caption uploader. That keeps you in control of font, position, and styling, and lets you edit a word before it ever goes on screen. Need subtitle files for a longer edit instead? See the subtitle generator.

FAQ

Caption questions.

How do I generate captions for a video?
Upload the video into the box above, and we transcribe its audio with Whisper Large v3 Turbo and split it into timed caption segments. Download the result as an SRT or VTT file and add it in your editor or the platform uploader. Captioning is a Plus and Pro feature.
Does it work if my video has no captions?
Yes — that is the whole point. We generate captions from the audio itself, so a raw export, a screen recording, or any clip that was never captioned comes back fully captioned. There is no need for an existing caption or subtitle track.
What caption file formats do I get?
Timestamped SRT and VTT for captions, plus TXT and PDF for notes and sign-off. SRT and VTT load into every major editor and social uploader.
Will the captions be in sync with my video?
Yes. Each caption segment carries a real start time taken from the audio, so the SRT or VTT you download lines up with the footage rather than drifting. Timing is per segment.
Can I caption videos in other languages?
Yes. Caption the clip once, then translate the caption text into 40 languages — so the same upload gives you captions for audiences around the world without re-transcribing.
Do you put the captions onto the video for me?
No. We generate a caption file (SRT or VTT) that you add in your editor or the platform caption uploader. That keeps you in control of the font, position, and styling, and lets you edit the wording before it appears on screen.
How much does captioning cost?
Captioning uploaded files is a Plus and Pro feature at 10 credits per audio-hour. Files can be up to 500MB and six hours long. Sign in on a Plus or Pro plan to start.
How accurate are the captions?
We use Whisper Large v3 Turbo, which holds up on background music, accents, and phone-quality audio. Captions come back as punctuated text, so they are readable at a glance and need only light editing before they go live.
“Half the clips I post are raw exports with no captions. I upload, download the SRT, and my Reels are captioned before I even write the caption copy — my mute retention jumped instantly.”
