Timing for every single word
Most auto-captions time whole lines, so they drift. AutoCap gives every word its own start and end, which is what keeps a karaoke highlight or a word pop exactly on the beat.
Captions that hit every single word.
AutoCap turns speech into captions with a timing for every word. Fix anything, pick a style, and export a captioned MP4 — or SRT and VTT files for any platform.
- No credit card
- 2 free minutes every month
- Only the audio is uploaded
141 styles, every word tunable.
Each style reveals word by word and highlights what matters. What you see here is the exact renderer the editor and the exporter use, so the preview and the finished video can't drift apart.

Everything a caption needs. Nothing it doesn't.
Not a video editor with captions bolted on. Every part of AutoCap is built around one job: getting speech onto the screen accurately, on time, and in a style worth posting.
Edit every word
A transcript is a starting point, not a verdict. Fix names and jargon, split lines, retime a single word.
141 caption styles
Word pops, karaoke fills and clean subtitles. Recolor any word and choose from dozens of fonts, or upload your own.
Rendered in your browser
Export runs on your own device. Your footage is never uploaded to be rendered, and exports are unlimited on every plan.
Up to 2K, nothing lost
Burned-in MP4 at up to 1440p, keeping your clip's frame rate and audio — never upscaled, never resampled.
SRT & VTT from the same edit
Subtitle files written from the transcript you corrected, ready for YouTube, LinkedIn, Premiere Pro and DaVinci Resolve.
From upload to captioned video in about three minutes.
No timeline to learn and no project to manage. Upload, fix what the model missed, pick a look, export.

Captions aren't a nice-to-have anymore.
People watch with the sound off on trains, in offices and late at night — and deaf and hard-of-hearing viewers rely on captions every time. Accessibility rules on both sides of the Atlantic, from the European Accessibility Act to the ADA and WCAG, increasingly expect video to carry them.

What is AutoCap?
AutoCap is an automatic caption and subtitle generator. Upload a video, get an editable transcript with a timing for every word, style the captions, and export either a video with the captions burned in or standard SRT and VTT subtitle files.
Is AutoCap free?
Yes. The free plan includes 2 minutes of transcription every month, clips up to 60 seconds, every caption style and unlimited exports with a small watermark. No credit card is needed. Paid plans remove the watermark and add more minutes.
Which languages does AutoCap support?
English and 38 more languages spoken across Europe, including Spanish, French, German, Italian, Portuguese, Polish, Dutch, Greek and Ukrainian. Pick the language when you upload, or let AutoCap detect it. The languages page lists every one.
Can I download SRT or VTT subtitle files?
Yes, on every paid plan. The files are written from the transcript you corrected, so your edits carry over. The free SRT to VTT and VTT to SRT converters work for anyone, no account needed.
Do you upload my video?
Only the audio is sent, to transcribe it. Rendering the captioned video happens on your own device, in the browser, which is also why exports are unlimited on every plan.
Your next video, captioned in minutes.
Start on the free plan — no card, no expiry. Paid plans from $19 a month when you're ready to drop the watermark.
