Anvil
Put an idea on the anvil and work it into a long-form story. Anvil gives writers and AI tools such as Codex and Claude Code one shared system for planning, drafting, revision, evidence, and quality gates.
How it relates to the guide
The guide argues that ordinary people should keep judgment, voice, and exits in the AI era. Anvil brings that principle into writing: AI can help, while the work, rules, evidence, and final decisions remain with the writer.
Why build it
AI can generate a convincing paragraph and still forget a promise, character, or cause from dozens of chapters ago. Long-form work needs more than text generation. It needs a system that can remember, check, revise, and carry a work to completion.
What makes it strong
Anvil does not lock writers to one model or quietly call an AI API to write prose from the CLI. Local files, Git, a TypeScript CLI, quality gates, and host hooks let different AI tools collaborate under one traceable writing contract.
What comes next
The current step is consolidating the working writing engine under one durable identity. Installation, onboarding, interface design, and distribution for general users will follow gradually; there is no promised launch date yet.
