Auto-Caption Short Videos with Animated Word Emphasis (Claude Cowork Self-Install Kit)

Post the captions that hold attention instead of the plain ones you settled for.

You spend longer captioning a clip than you spent filming it, so the styled version keeps losing to the version you can actually ship. You batch-film on Sunday and you're already behind by Wednesday.

The leak isn't your filming pace. It's that every clip needs a caption pass before it can go out, so the queue backs up behind the slowest part of the job.

What this kit does

The kit hands the whole caption loop to Submagic. You upload the clip and word-by-word animated captions with color emphasis and zoom effects come back, no exporting, timing, or re-exporting by hand.

What you can expect

You get back 45 to 90 minutes of caption work per video, and the caption pass itself runs in under five minutes instead of eating your afternoon. At 4 to 5 clips a week that's 3 to 7 hours of production time returned, and the styled version stops being the one you skip.

Who it's for

Built for content creators, coaches and consultants, and solopreneurs shipping short-form on a schedule they'd like to keep. This is a self-install kit you run yourself with your own AI agent, built for Claude Cowork first.

What's included

Skip building from scratch. No coding. You get the complete kit your own AI agent reads, sets up, and runs for you, step by step:

• A Start Here guide, so you know exactly what to open first
• The agent install instructions, the part that lets your own AI agent stand the workflow up for you
• A guided setup that interviews you about your business, so the workflow fits how you actually work
• Workflow Briefing: the plan, the inputs, and what done looks like
• Task List your agent follows to build it
• MCP Connection Guide for the tools involved
• Tool Setup notes for accounts, keys, and permissions
• Prompt Library, including the ready-to-run prompt for this workflow
• Troubleshooting and maintenance guide for the common snags
• A Next Steps and Roadmap, so you know what to automate next once this one is running
• A Run Guide you keep, so you can run it any time with no setup again

This one's free, and it's a real kit, not a teaser. You keep it, you run it on every clip you cut, and the Next Steps and Roadmap inside points you at what to automate once this one is running.

What you'll need (not included)

The kit is the workflow, the prompts, and the setup guide. It does not include the tool subscriptions it runs on. You'll need your own Claude with Cowork account and a Submagic account. Those are billed by the tools themselves, not by us.

You'll also need your Claude account on Cowork's Pro plan or higher, so your agent can connect your tools and use the most capable model while it installs the workflow.

Not on Claude? The kit is plain files that describe what to achieve rather than which buttons to press, so a capable AI agent on another platform, like ChatGPT Work, can follow the same steps. If anything doesn't map to your setup, email support and we'll get you working.

How to install this kit

Connect Submagic to Claude using the MCP Connection Guide in the kit and authorize your account. Open the kit in Claude Cowork, run the included prompt, and push a clip through end to end so you can see the caption style come back the way you want it. Step-by-step instructions ship inside every kit, so you're never guessing. See How Self-Install Kits Work for the full walkthrough.

Install once, not every month

If you've been pricing video captioning software, this is the install-it-once alternative. You set it up yourself with your own AI agent and keep it, with no monthly seat. Add it to your cart, open it in Claude Cowork, and caption the clip that's been sitting in your drafts.
