The whole workflow →

Design in the meeting, not after it.

A drawing program

  • Learn the tool first
  • Place every wall and door by hand
  • Take the feedback away, come back next week

Flawlessplan

  • Nothing to learn: you talk
  • The agent draws, you decide
  • The change is on the plan before anyone leaves

For whoever is still deciding

Your own home

Try the extension before you pay anyone to draw it.

Architects and designers

Sketch the options with the client in the room.

Builders and the trade

A plan in minutes, to talk a job over or price from.

To scale, but not construction drawings.

Fast, and still right

Measured, never typed
Every room size is read off the drawing.
Say a figure once
Correct one measurement and everything follows.
It checks itself
Every change is validated, so the agent catches its own mistakes.
