Top 3 New AI GitHub Repos for April 2026

Chase rounds up his three favorite AI GitHub repos created in April 2026, covering design systems for front-end work, a token-saving skill for Claude Code, and an AI-powered job application tool. Each repo solves a specific pain point for developers and AI power users.

1. Awesome Design

The first pick is Awesome Design, a repo aimed at anyone doing front-end work. It lets you browse a curated list of websites and copy their aesthetic into your own projects. Choose a site like ElevenLabs, and the tool generates a complete design system inspired by their page -- colors, fonts, spacing, card components, everything. It is essentially a shortcut to professional-quality design systems without starting from scratch.

2. Caveman

The second repo is Caveman, a skill and plugin for Claude Code that makes the model less verbose. It significantly reduces the number of output tokens Claude uses to generate answers. Chase notes that he actually uses this one himself. The repo links to studies showing that the reduced verbosity might also improve Claude's reasoning performance -- fewer words, better thinking. The tagline says it all: "why use many token when few do trick."

3. CareerOpt

The third repo is CareerOpt, and it targets job seekers. It uses Claude Code to automate the job application process -- evaluating offers, scanning job portals, and generating tailored PDF resumes and cover letters. For anyone who needs to send out a high volume of applications, this turns a tedious manual process into an automated pipeline.
