Captionly – Word Synced Videos That Convert – a one-page tool that turns a topic or URL into a polished, word-synced “caption” video in under 60 seconds — voiceover and all, straight to MP4. Unlimited use, no subscription. Runs in your browser with your own API keys.

Captionly makes the scroll-stopping, word-synced videos you’ve seen in top-converting ads – the ones where each word lights up as it’s spoken.

Paste a topic or any URL, pick a voice and theme, and MP4 comes out in under a minute. No camera, no mic, no editing software.

Every video ships with a ready-to-paste YouTube SEO pack (title, description, hashtags, timestamps), an .srt file, your logo, background music and an end CTA with your link. 15 languages, 10 editorial themes, and unlimited use – no monthly fees.

It runs right in the buyer’s browser using their own Anthropic (Claude) and ElevenLabs API keys, so there’s nothing to install and no recurring cost to the tool.

Perfect for paid ads, affiliate promos, blog post videos, local business adverts, and your own product launches. If you can copy and paste, you can make these videos.

Demo Video Walkthrough

Word-synced, moving-text videos pull people in and keep them watching. Retention is high because the format itself gives the eye something to follow — which is exactly why they work so well as ads and promos.

But actually getting them made was the painful part. I used to pay someone on Fiverr around $75 for a single video — or sit in Canva for hours nudging text boxes into place, frame by frame, to make just one.

Captionly collapses all of that into one screen. Paste a topic or a URL, hit generate, and a finished word-synced video comes out the other side — in under a minute. Then make as many as you want.
One brief in. A polished, captioned video out. No camera, no mic, no editing software, and no $75 invoice.
