AI translates business needs
into structured PRDs, automatically.

Free-form requests are auto-converted into template-based, structured PRDs. Codebase analysis, a review/approval workflow, and bidirectional Notion sync bridge business and engineering.

How It Works

From idea to engineering hand-off — end to end

1

Idea consultation

Chat with AI to organize requirements right from the concept stage. Even without a registered repository, you can start with just "what we want to do".

2

Codebase analysis

The Claude Agent SDK analyzes your GitHub repository and captures the context of the existing implementation, so you can write PRDs that extend existing features.

3

AI PRD structuring

Free-form text and chat content are auto-converted into structured PRDs that follow your project's template — background, goals, requirements, and acceptance criteria all organized.

4

Review and approval workflow

Assign reviewers and request approval. State transitions from draft → pending_review → approved and per-section comments make consensus visible.

5

Bidirectional Notion sync

Approved PRDs sync to Notion, and Notion-side edits flow back into the PRD. Share PRDs as the single source of truth without leaving your everyday tools.

Hand-off to engineering

Push approved PRDs out as Slack notifications, Jira tickets, or external task entries. Hand-off to Purple Codens or Blue Codens is one click away.

AI closes the language gap

Business wants to write "what we want to do".
Engineering wants to implement "what's been decided".
Green Codens stands between the two, translating free-form text, existing code, and your
organization's templates into PRDs that readers can act on.

Core Features

Write, align, iterate, and hand off PRDs — all on one platform

AI PRD structuring

Auto-converts free-form requests into template-based structured PRDs — background, goals, requirements, and acceptance criteria all organized.

Idea consultation chat

Even without a registered repository, organize requirements via chat with AI from the concept stage. When the discussion is solid, turn it into a PRD directly.

Codebase analysis

The Claude Agent SDK reads your GitHub repository and grounds PRD generation in the existing implementation — perfect for "extend the X feature in this app" themes.

Custom templates

Define PRD structure per project. Reuse the best practices accumulated across your organization as a "shape" for every new PRD.

Review and approval workflow

Make consensus visible with reviewer assignment, approve, send back, and per-section comments. Track state transitions across draft → pending_review → approved.

Version history

Change history is saved automatically and diffs are easy to compare. Trace the rationale behind decisions and "what changed when" after the fact.

Bidirectional Notion sync

Sync PRDs with Notion so edits in either place stay in sync automatically. Maintain a single source of truth for your internal documentation.

Slack / Jira / external task integration

From an approved PRD, fire Slack notifications, create Jira tickets, or register external tasks in one click. Drops right into your existing team workflow.

Codens family integration

Pass approved PRDs straight into Purple Codens (implementation) or Blue Codens (QA / E2E test generation) — the starting point of your dev chain.

Get Started in 4 Easy Steps

From business team members to engineering — bring everyone in instantly

1

Create your account

Sign up at auth.codens.ai. Create an organization and invite both business and engineering members.

2

Create templates

Define PRD templates for your project (a default template is also available). Lock in your organization's conventions as a reusable shape.

3

Connect repos and Notion

Connect a GitHub repository (optional) and your Notion workspace. This activates codebase analysis and bidirectional sync.

✓

Author, approve, hand off

Create a PRD from idea consultation or free-form text → review and approve → sync to Notion → push to Slack/Jira/Purple/Blue.
