Agents build fast. The bottleneck is knowing what to build.

19%

slower. Developers using AI were measurably slower — despite believing they were faster.

91%

longer reviews. PR volume doubled. Verification became the bottleneck.

30-50%

of engineering time clarifying requirements. 15-30% rework from ambiguous specs.

Three ways in

Start from anywhere.

Different contexts need different entry points. Start however feels natural — you'll get the same structured spec.

Chat

Talk through your idea with an AI PM. Conversational, iterative, natural.

Wizard

Describe your goal, answer targeted questions, review the output. Structured and fast.

Meeting notes

Paste raw notes or a transcript. The AI extracts decisions, requirements, and gaps.

After the first draft

A coach, not just a generator.

The AI Coach reviews your spec like a CPO would — questioning assumptions, flagging weak areas, pushing you to think deeper. Drop in mockups or screenshots for richer context. Customize the coach's tone and domain expertise to match your team.

Review my spec for the returns flow

Your goal and user stories are solid, but I see two areas worth tightening:

"What happens when a user tries to return a gift they didn't buy? Your spec assumes the purchaser is always the requester."

What's your refund SLA? The spec says "same-day" but doesn't define what happens after business hours.

Good catch — should be next business day outside hours

Understood goal

Add a returns flow to the e-commerce app

e-commerce·workflow

Do gift recipients get the refund, or the original purchaser?

This determines the refund routing logic and notification flow

 

Should customers be able to return individual items from a bundle?

Partial returns on bundles require inventory reconciliation

 

The process

The questions a senior PM would ask.

Domain-specific clarifications — gift return routing, bundle pricing logic, fraud edge cases. Short answers are fine. The AI infers the rest.

Ship to where code gets built

One click to export your spec in the format your tools expect — whether that's a human reading Markdown or an AI agent executing Cursor rules.

Repo-aware

Specs that know your codebase.

Connect your GitHub repo. ClearSpec reads your file tree, dependencies, and recent PRs — then generates specs that reference actual code. No source code stored.

Without context

“Add refund support. Should handle full and partial refunds with proper error states.”

With GitHub context

“Add POST /api/refunds in src/routes/payments.ts using the existing StripeService from src/services/stripe.ts. The OrderV2 schema from PR #487 applies.”

IDE Integration

Specs flow into your editor.

Your AI coding assistant pulls specs directly from ClearSpec — structured sections, always the latest version, zero copy-paste.

Structured context

Goal, user stories, edge cases, and failure states — delivered as structured data, not pasted text.

Always current

Every request pulls the latest version. No stale screenshots or outdated copies.

FAQ

Common questions

A structured spec with a goal statement, user stories with acceptance criteria, edge cases, failure states, dependencies, out-of-scope list, and verification criteria. It's formatted as markdown so you can paste it into Claude Code, Cursor, or any agent that reads text.

Traditional PRDs are written for humans in meetings. ClearSpec generates specs structured for AI agents — with the specific sections (edge cases, failure states, out-of-scope) that prevent agents from hallucinating scope. You describe the feature in one sentence; the AI fills in the rest.

Under 60 seconds. You type a plain-English description, optionally answer a few clarifying questions (or skip them — the AI fills in sensible defaults), and get a complete spec.

Free tier includes 5 specs per month. Pro ($10/month) is unlimited specs with priority generation and the AI Coach review feature.

Any agent that reads text: Claude Code, Cursor, Codex, Windsurf, Aider, and others. The output is plain markdown — copy-paste it into your agent's context, CLAUDE.md, .cursorrules, or chat.

No. Skip any question you're unsure about — the AI applies sensible defaults for your domain. You can always edit the spec after it's generated.

Your engineers need clarity. Your agents need structure.
