Spec Writer

From idea to structured spec in minutes.

Describe your goal. AI asks clarifying questions. Get a complete specification with user stories, edge cases, and failure states.

01How it works

Describe once. Get everything.

You describe the feature in plain English. ClearSpec asks the right clarifying questions — the kind a senior PM would ask — then generates a complete spec with every section an engineer needs.

Natural language input

No forms or templates to fill. Just describe what you want to build.

Domain-aware clarifications

Questions adapt to your feature type — e-commerce, SaaS, API, mobile, infrastructure.

Complete output in one pass

Goal, user stories, edge cases, failure states, acceptance criteria — all generated together.

GitHub-aware context

Connect a repo and specs reference your actual codebase — real files, real services, real schemas.

02Quality built in

Specs tight enough for agents to execute.

ClearSpec doesn't just generate text — it generates structured specifications scored for completeness. Every section is designed to eliminate follow-up questions from engineers and ambiguity from AI agents.

Completeness scoring

Real-time score from 0-100% based on coverage of goals, stories, edge cases, and failure states.

Failure state coverage

Every spec includes what happens when things break — timeouts, sync failures, fraud, edge cases.

Structured for agents

Export as Cursor Rules, Agent Prompts, or Claude Code format — structured enough for AI to execute without hallucinating scope.

Iterate with AI Coach

After generation, the AI Coach reviews your spec like a CPO — questioning assumptions and flagging gaps.

Without ClearSpec

4-6 hours writing a PRD from scratch
Missing edge cases discovered during code review
Engineers ask 10+ clarifying questions before starting
AI agents hallucinate scope from vague specs
Specs become outdated before implementation starts

With ClearSpec

First draft in under 5 minutes
Edge cases and failure states generated automatically
Specs precise enough to build without follow-ups
Structured output agents can execute directly
Living specs that version and evolve with your project
