Shorts Kit

Shorts Kit is an open source toolkit designed for creators who want to automate and streamline the production of narrated vertical short-form videos for platforms like TikTok, YouTube Shorts, and Instagram Reels. Drawing from hands-on experience running a growing TikTok knowledge channel, Shorts Kit packages a set of agent-based workflows that guide the user through each stage of video creation—starting from researching verified facts, moving through story structuring, scripting, text-to-speech narration, and visual scene composition, to final renders and caption generation.

The system uses a coding agent (such as Claude Code or similar tools) to handle nine distinct skills within the video creation pipeline. It also comes equipped with a detailed rulebook for storytelling, voice and sentence style, caption placement, and video composition—each justified by hard-learned lessons from past video performance. The included fact ledger ensures that all claims in scripts are supported by verifiable information before production continues, with automated linting to enforce high standards throughout.

Out-of-the-box, Shorts Kit provides over 20 storytelling templates, a storyboard planning system, and a library for creating timed captions, kinetic typography, and animated illustrations. It features map and globe visualizations, built-in CC0 sound effects, and scripts for everything from TTS narration to platform-ready encoding. A preview dashboard helps creators review progress and make adjustments before publishing. By covering technical and narrative best practices, the toolkit saves time and offers best-in-class workflow for small creator-led studios looking to scale their presence in vertical video formats.

Content creators who want to make narrated short-form videos more efficiently, especially those with a technical or educational angle. This tool best suits solo creators, small teams, or independent channels aiming to grow their audience on TikTok, YouTube Shorts, or Reels with fact-checked, well-structured, and visually polished content.

It’s especially relevant for developers and makers familiar with TypeScript and open source workflows, as well as marketers, educators, and creative leads at startups or media agencies who want to produce consistent and high-quality video content without needing a dedicated production team.
