One tool for the whole planning workflow
From the first wall you draw to the quote you hand a customer — every step lives in NexusPlan.
Floor Plan Drawing
Draw walls, doors, windows, stairs and rooms with smart snapping, or import an existing plan (PDF or image) and trace over it to scale. Assign wall materials — brick, drywall, concrete, glass — so every simulation reflects how your building actually behaves.
AI Floor-Plan Detection
Upload a floor plan and let AI trace the walls, find the doors and windows, and estimate the scale — a working layout in seconds, ready to refine. You bring your own AI provider key (OpenAI, Anthropic, Gemini or Grok); we never mark up the tokens.
AI Assistant — Bring Your Own AI
Ask an assistant to review coverage, place devices, or draft a layout — running on your own OpenAI, Anthropic, Gemini or Grok key. Prefer your own tools? Connect NexusPlan to Claude Desktop, Cursor or any MCP client and drive it from there. You bring the AI; we bring the plan.
Device Library
A catalogue of real smart home devices — hubs, sensors, switches, cameras, speakers, thermostats — each with its protocol, power requirements and price. Drag them straight onto your plan and NexusPlan keeps track of what talks to what.
Protocol Signal Simulation
See signal coverage as a live heatmap over your floor plan. Simulation accounts for wall materials, distance and interference so you can find dead zones, place repeaters and size your mesh before anything is installed.
Theatre Planner
A dedicated mode for home cinemas and media rooms: speaker layouts (5.1 to Atmos), seating positions, screen size and viewing angles — with acoustic simulation to check reflections and bass response for the room.
Acoustic Simulation
Model how sound behaves in any room — not just theatres. Select a room from your floor plan, set wall materials, and get instant RT60 estimates, room mode analysis, and speaker coverage recommendations before you mount a single bracket.
3D Visualisation & Print
Flip any plan into an interactive 3D view. Walk the rooms, check device placement at real heights, and share the walkthrough so clients or family can see exactly what they are getting — or export a 3D-printable model (.3mf) of the building, floor by floor, roof and all.
BOM & Quote Export
One click turns your plan into a complete bill of materials. Pro users generate branded customer quotes with their own logo, terms, device pricing and labour rates — ready to send.
Bring your own AI — you supply the key
The AI features run on your own provider account. Add a key from OpenAI, Anthropic, Google Gemini or xAI Grok in Account → AI, or connect your own AI client (Claude Desktop, Cursor, or any MCP client) with a personal access token. Your provider bills you directly at cost — NexusPlan never marks up the tokens. Available on Pro Team and Business.
