Caption

Style

Pick a caption look and size it, space it, box it your way.

Export

Download a finished MP4 — your original audio kept intact.

From clip to post in minutes.

Buy on Gumroad → get your license key → paste it into the studio to unlock.

Good to know

Questions, answered.

No. The studio runs entirely in your web browser. Open the link, paste your license key, and you're working — on the computer you already have.

No. It's a one-time purchase. You buy it once and it's yours — no monthly bill.

When you buy on Gumroad you get a unique license key. Open the studio, paste the key once, and it unlocks on that device.

Short-form vertical clips — Reels, TikToks, Shorts. Upload your clip, caption it, style it, and export a finished post.

Transcription is good, and when it mishears a word you fix it in one click — your correction updates the caption and stays in sync.
