Ralph Wiggum Marketer is a Claude Code plugin that serves as an autonomous AI copywriter tailored for SaaS content marketing, enabling automated generation of marketing copy such as landing pages, taglines, feature summaries, and promotional messaging. It leverages the Ralph Wiggum loop concept — a continuous iteration pattern named after the iconic character that symbolizes persistent, repeated refinement — to let Claude Code keep iterating on content until predefined completion criteria are met, rather than stopping after a single output.
