What you need
- Windows 11, 64-bit (Windows 10 21H2+ is a legacy target).
- A folder for the project. Planning files live beside application source, never inside it.
- Optionally, Git and an AI provider account. Neither is required to inspect or edit a project locally.
Create a project
File → New Project asks for a name, description, type (web, desktop, mobile, API, AI application, SaaS, library or other), target platforms and an optional stack. Project Planner then writes two things at the chosen location:
- A
.ppidentity file in the project root. See Project identity. - A
project-planner/directory with canonical sections for requirements, architecture, agents, development, security, testing, decisions and the blueprint.
If you open an existing folder that already has a .pp file, Project Planner loads that identity and does not create a second one.
Describe the idea
The Overview screen starts with the description you typed. The Product Planner and Requirements Analyst can propose a first set of phases and candidate requirements. Every proposal is a draft until you accept it. Nothing is written into the plan automatically.
Work through the lifecycle
- Accept, edit or reject proposed requirements. Each one gets a stable ID such as
REQ-001. - Turn accepted requirements into phases, milestones, tasks and subtasks.
- Add architecture components and the data that moves between them.
- Open the System Map and Data Flow screens — they are generated from that data, not drawn by hand.
- Assign agents, skills and MCP servers if you want AI assistance. Configure a provider first if you want model-backed runs.
- Run audits. Findings carry evidence, severity and a recommendation.
- Generate the blueprint and export it as Markdown, JSON, HTML or PDF.
