# AfterPencil

> AfterPencil is a browser-based floor plan application for making better decisions before building. One semantic project drives the measured plan, 3D views, sunlight, materials, quantity takeoff and technical documents. People can begin without an account; cloud projects add continuity and sharing.

## Audiences

Stable audience ids: `homeowners`, `architects`, `builders`, `developers-and-agents`.

- Homeowners and renovators: bring an existing drawing or start from scratch, test alternatives and share a clearer project.
- Architects, interior designers and students: keep exact dimensions while presenting client-readable views, quantities and documents.
- Builders and contractors: inspect geometry, preliminary quantities and files without treating them as a closed estimate or signed construction documentation.
- Developers and agents: use documented, permissioned interfaces instead of guessing through pixels.

## Pricing

- Free: complete everyday modeling, local 2D and 3D, quantities and core documentation.
- Plus: $10 per month or $90 per year. Higher costly-compute allowances, advanced files and integrations.
- Pro: $30 per seat per month or $250 per seat per year. Shared capacity and studio workflows.

An agent must use only the access granted by the person and workspace role. Read the relevant state, make an explicit change, inspect the structured result and verify it through plan or 3D output before reporting success.
