Answer domain-specific questions
PromptArch guides you through intent, context, and constraints instead of dropping you into an empty text box.
PROMPT & CONTEXT ENGINEERING WORKBENCH
Context engineering for AI agents.
Architect every file they read.
Generate and lint CLAUDE.md, AGENTS.md, Cursor rules, Copilot instructions, and 17 artifact types, plus scored prompts for every workflow. In the browser, from the CLI, or over MCP.

Context Engineering Studio
One brief. Every config file your stack needs.
Describe your project once. Studio emits CLAUDE.md, AGENTS.md, Cursor rules, Copilot instructions, and more, each within size budgets and linted before you ship.

Frequently asked questions
What is context engineering?
Context engineering is the practice of designing the instructions, files, and constraints that guide AI agents, like CLAUDE.md, AGENTS.md, and Cursor rules. PromptArch is a workbench for building them.
Do I need an account to try it?
No. You can generate one prompt free with no signup. Create an account to save, copy, share, and generate more.
Which AI models and tools does PromptArch support?
PromptArch generates prompts and dev-tooling artifacts for Claude, GPT, Cursor, Windsurf, GitHub Copilot, and more, with output tuned per target.
Is there a CLI?
Yes. Run `npm install -g promptarch` to get `promptarch lint` (free, offline, CI-friendly exit codes) and `promptarch init`, which scans your repo and generates CLAUDE.md, AGENTS.md, Cursor rules, and Copilot instructions.
Can my AI agent use PromptArch over MCP?
Yes. The promptarch-mcp server speaks Streamable HTTP. Point Claude Code, Cursor, or any MCP client at it to lint artifacts for free, or generate them with an API key.
