Why Compozit exists
A listing in one tab. A budget in your head. A bylaw nobody explained. Photos, a sketch, a quote. Change one and the rest stop agreeing.
One agent, one project
Compozit holds them together.
Your lot, your life and its limits stay attached to one project. When something moves, the plan moves with it. What nobody knows yet stays marked as unknown.

Plan v3 · redrawn whenever one of these changes
How it works
Lot
Start from the lot, not a blank page. Its shape, its street and its sun come first.
Life
Say how you live. Rooms, and the way you move between them, become a programme.
Limits
Setbacks, height, heritage. What is known is applied. What is not is flagged to verify.
Plan
The programme settles into a plan you can push, pull and question.
Change
Change your mind. The plan re-lays itself and shows what moved and what it costs.
You
Put the office on the garden side. I want the light.How it works

The four lenses
Design lens
Photograph a room, describe the feeling, and get photo-real before-and-after direction tuned to your budget, location and taste, in under thirty seconds.
Property lens
Voice-first property search tuned to your budget, location, taste, and renovation potential, not just filters and square footage.
Regulation lens
Early constraint awareness for Quebec and Montreal. Zoning, heritage and structural questions surface as flags to verify, before the concept becomes a project.
Build lens
From concept to sourced path: materials, finishes, suppliers, price ranges, and project inputs that match your design and budget.

Honest by design
01
When a setback, a price or a soil condition is not known, Compozit says so and tells you who can confirm it. It never fills a gap with a guess dressed as a fact.
02
Every change arrives as a proposal you can read, compare, accept or undo. Nothing on your plan moves behind your back.
Proposal
Move the stair 1.2 m east to free the entry.
2 walls, 1 door · no cost change
03
The same agent remembers your lot, your family and your taste, from the first photo to the first contractor call, on your phone or at your desk.

Compozit starts with homes in Québec. The method underneath, lot first, life second, limits always, is the same one the places we share will need.
Where this goes
Compoz · the Compozit Lab
Research previewCompoz is our construction-reasoning engine. It models buildings the way engineers think about them, starting from purpose, not parts, and an autonomous research agent grows its knowledge library around the clock, from cited sources, with every entry reviewed by a human before it counts.
Assembling the frame.
This is the research that will power the Check and Flow lenses: materials, assemblies and risk questions grounded in cited sources and real physics, starting with Quebec.

Questions
Compozit is an AI agent for home transformation and property development. It learns your budget, location, and taste, then turns a rough idea into photo-real design direction and a buildable plan. One agent carries your context across four lenses: Vision for design, Lens for property search, Check for regulation awareness, and Flow for the build. Built in Montréal, Québec first.
Compozit is one AI agent that holds a home project together. It keeps the lot, how you live, and its limits, like setbacks, height, and heritage rules, attached to one editable plan, so the building changes with the decision instead of after it. What is not yet known stays marked unknown. Built in Montreal, Quebec first.
Yes. Vision, the design lens, is live now on the iOS App Store. It turns a room photo into photo-real before-and-after direction in under 30 seconds. The other three lenses, Lens, Check, and Flow, roll out from late 2026 through 2027, Montreal and Quebec first.
Vision is Compozit's design lens and the first product live today. Photograph a room, describe the feeling, and get photo-real before-and-after direction tuned to your budget, location, and taste in under 30 seconds, with voice and chat refinement, 150+ design styles, and cost estimates. Available now on the iOS App Store.
Most AI design tools stop at a pretty picture, one project at a time. Compozit sources real furniture at real prices from real stores, gives cost estimates that hold up, and is built to carry that same project forward: into property search, regulation awareness, and sourcing, as one continuous plan instead of a new prompt each time.
Yes. Vision's renders are built from real products at real prices from real stores, so the before-and-after you see is something you can actually buy and budget for, not a generic AI mockup. Cost estimates are attached to every design so the plan holds up in the real world.
That is the Check lens, coming to Montreal and Quebec from late 2026. Check is designed to bring Quebec building codes and Montreal borough zoning, setback, and heritage rules into the plan as flags and checklists, so a limit surfaces before you build against it. Check gives awareness, not permit approval; a confirmed limit still gets verified with the relevant authority.
Compozit is built in Montreal and launching Quebec first. Vision works on iOS today; the property, permit, and build lenses, Lens, Check, and Flow, launch across Montreal and Quebec through 2026 and 2027.
