GenerateSpecs is a web-based tool that generates highly-detailed product specifications for AI-assisted application development. It takes a simple description of your app idea and, through an interview process and agent-driven loop, produces a comprehensive spec document (6,000–12,000 lines) covering system architecture, database schema, tech stack, design patterns, features, API endpoints, security, and build instructions. The spec is delivered to your inbox within 1–3 hours. GenerateSpecs is designed to be used with AI coding harnesses like Claude Code, Codex, and CRHQ, enabling agents to build production-ready applications without guessing.
What is GenerateSpecs?
GenerateSpecs is a SaaS tool that converts a basic app idea into a detailed, production-ready product specification. You input your requirements, answer interview questions, and the platform's agents run a loop to generate a comprehensive spec document. The output is a structured spec that includes architecture, database schema, tech stack, design patterns, every feature screen-by-screen, every API endpoint, security considerations, and step-by-step build instructions. The platform is web-based and accessible via a browser.
Key Features
- Detailed Spec Generation — Produces 6,000–12,000 line documents covering eight parts: system architecture, database schema, tech stack, design patterns, features, API endpoints, security, and build instructions.
- Interview Process — Guides users through a series of questions to refine requirements before generating the spec.
- Agent-Driven Loop — Uses AI agents to iterate and produce a comprehensive spec, delivered to your inbox in 1–3 hours.
- Integration with AI Harnesses — Provides copy-paste prompts for Claude Code, Codex, and CRHQ to use the spec for building the application.
- Project Builder Agent — CRHQ's Project Builder can execute the spec through implementation, QA, code review, polishing, and gap closure.
- Launch Offer — First 100 specs are free (93 of 100 left), one per person.
Who is it for?
- Developers — Use GenerateSpecs to create a detailed spec before starting a project, ensuring AI agents build exactly what you need.
- Startup Founders — Quickly turn a product idea into a buildable spec, reducing time from concept to MVP.
- AI Enthusiasts — Leverage the spec with Claude Code, Codex, or CRHQ to build production-ready apps without manual architecture planning.
What can you do with GenerateSpecs?
- Clone existing products — Use the spec to rebuild SaaS products like Tally, Granola, or Plausible, as tracked by canivibecodeit.com.
- Build from scratch — Describe your own app idea and get a detailed spec that AI agents can follow to build the full application.
- Streamline development — Hand the spec to an AI harness like CRHQ's Project Builder, which handles implementation, testing, and code review in a single session.
