Auto Caption Instagram Reels
To auto caption an Instagram Reel, upload the clip here, let the AI transcribe the audio, choose one of three caption styles, and download the Reel with captions already rendered into the video — ready to post.
Most Reels are watched on mute, in feeds, waiting rooms and offices. A Reel without captions loses those viewers in the first second; a captioned one delivers its message silently. Automatic transcription gets you there without typing a word.
How it works
- 1
Upload your Reel
Drop in your vertical clip, up to 500 MB. Pick the audio language — English, French, Spanish or German — or leave auto-detect enabled for mixed content.
- 2
Style and place your captions
Choose TikTok-style bold highlights, Classic subtitles, or the handwritten Dream look. Use the custom height option to keep text above the Instagram caption overlay at the bottom of the frame.
- 3
Download and share to Instagram
Download the captioned Reel and post it from the Instagram app. The text is part of the video, so it displays for every viewer regardless of their caption settings.
Why use Video-Matic

Bold TikTok highlights for energy, Classic for a clean brand feel, Dream handwriting for softer aesthetics — pick per Reel.
First Reel captioned free
Signup includes 3 free credits and captioning costs 3, so you can test the full workflow on a real Reel before paying anything.
Fast, browser-based workflow
No desktop editor and nothing to install — upload, caption and download from the same phone you film on.
Frequently asked questions
Why not just use Instagram built-in captions?›
Instagram auto-captions are a sticker viewers see only inside Instagram, with limited styling. Burned-in captions travel with the file: the same captioned Reel can be reposted to TikTok, Shorts or a website, and the styling — including word-by-word highlighting — stays exactly as you designed it.
What does auto captioning a Reel cost?›
A caption job costs 3 credits and new accounts start with 3 free credits, so your first Reel is free. After that, one-time credit packs on the pricing page keep you going — there is no subscription and nothing renews automatically.
Can I control where the captions appear on my Reel?›
Yes. Choose bottom, middle or top, or set a custom height as a percentage of the frame. On Reels it is smart to raise captions slightly, since Instagram overlays the description and action buttons over the lower part of the video.
Is my footage kept on your servers?›
Only briefly. Uploads and captioned results are deleted automatically within 24 hours, and processing happens on EU servers located in Paris. Nothing is shared, and the finished Reel has no added watermark.
