# Hemingway AI

> Turn local dev sites into live copy editors that write to source

Hemingway AI is an open-source tool that turns your localhost marketing site into an interactive copywriting canvas. Clicking any text element generates AI-written alternatives calibrated to the page's structure and voice. Selecting an alternative immediately updates the live page and writes the edit back into your local source files.

## Why it was saved

- [@hunterhammonds, 3 March 2026](https://x.com/hunterhammonds/status/2028876079570522131): Double-click any text element to edit freely, or click any heading/paragraph/button/link to get three Claude-written alternatives calibrated to copy job, context and page position. One click applies to the live page and writes the change back to your source file — no copy-paste, no round-trips. Features: Local-first (goes to Anthropic's API only), framework-agnostic (one script tag works with React, Vue, Svelte, Astro, plain HTML), writes to source (changes go to source files, not the DOM), context-aware (builds a page brief before every generation). Free and open source.
