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.
What it's for
- Refine landing page headlines and CTAs directly on localhost
- Generate context-aware copy alternatives aligned with brand style guides
- Write edited text back into project source files without manual copying
Features
- In-browser editing by clicking headers, paragraphs, buttons, or links
- Generates three context-aware copy variations based on page position and role
- Direct source-file writing without touching files manually
- Framework-agnostic integration using a single local script tag
- Local-first architecture that connects only to your AI provider API
- Custom style guide support to enforce brand voice
- Preference learning based on which suggestions you accept

Why it was saved
- @hunterhammonds: 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.
