Browser-based BIM platform · Works with your own AI

Every building should have a digital twin. Build yours in the browser.

Skanna is a BIM platform that runs entirely in your browser. Model the building yourself, connect your own AI to model it through the Skanna MCP connector, or pay a one-off price to have it digitised for you. Out come dimensioned drawing sets, an interactive twin anyone can open on a link, and data on every object, all from one model that stays with the building for as long as it stands.

A live link, not a mock-up. The finished building opens in your browser with no account. Nothing to install: the whole platform runs in the browser, and accounts are open now.

Running todayOn site on multiple continents, making drawings and digital twins. For a 100-unit housing development it produces the drawings, the visualisations and the operations and maintenance system, all from one model. They are dropping clunky CAD tools and scattered systems for booking, service and unit records, cutting their overall cost, and getting software shaped around the way they actually work.
AdaptableOne house or a whole development. Drawings, sales visuals, renovation, operations. Use it for what you need.
Pay for what you useFair pricing: a plan for your own buildings, seats for companies, or a one-off price to have a building digitised.
Open, web and AI friendlyRuns in the browser. IFC, DXF, PDF and GLB out, in a model format your own AI can read and write.

What it is, what it costs, how to start

Skanna gives a building one living model. Start from a scan, a drawing, a CAD file or your own AI, and get dimensioned drawings, rendered visuals and a twin anyone can open on a link. The iPhone scanner is free, and the modelling tool runs in your browser.

Skanna Web · BIM Author

The modelling tool, entirely in the browser, built so an AI can use it, and just as usable by hand. Connect your own AI and it drafts the model through the Skanna MCP connector. Or do it yourself: trace a scan, a splat, a CAD file or an old floor plan, or draw from nothing, and build a real IFC building model floor by floor, with every wall, opening, fixture and service run carrying its real specification. Either way it is the same model, and you can take over from the AI at any point. No CAD seat, no plug-ins, no workstation. Most people are productive in it in a day.

Everything comes back out in open formats: IFC for the model, GLB for the geometry, DXF, SVG and PDF for the drawings. Take them to SketchUp, Revit, Blender or any other platform, or keep working here. Nothing is trapped.

Digitise a building with your own AI, or have it done for you

A Skanna building model is documented, open JSON, not a proprietary binary or a licensed API. So your own AI can author the model directly, through a connector that is live today, and nobody has to force an MCP into a closed CAD system that was never going to let it in. Done properly, one professional with their own agents does the drafting of a whole CAD department: an army of drafters that costs what your tokens cost.

Connect your own AI · free to draft

The Skanna MCP connector

Add Skanna to ChatGPT, Claude or any AI that takes MCP connectors: one URL, no login. Give it your drawings, scans or files and it drafts the model floor by floor, checks it with the same code the app uses, and draws the plans and elevations for you to compare against the source.

  • Drafting is free. Open the claim link your AI gives you and the building moves into your Skanna account, where hosting it counts against your plan.
  • Every draft is labelled AI-drafted: checked as sound, not verified against the building. A person still compares it with the source.

Connector URL: https://mcp.skanna.site/mcp

Done for you · one-off price per building

Have your building digitised

Send me what you have: DWG or DXF, PDF drawings, scanned paper, LiDAR scans, photos or a 3D model. Tell me what you want at the end. I model it with a person checking every step against the source, and hand over the model, the drawing set and a published twin.

  • One price per building, quoted up front. It depends on what goes into the twin, what information you already have, and whether you want to work in rounds.
  • Changes after a round are billed as an extra round, so every piece of work is accounted for.

Started a draft with your own AI already? Include its claim link and I'll pick it up from there.

Optional: the Skanna iOS app

The Skanna app icon

Scan a building with your iPhone or iPad Pro

You don't need it to use Skanna. If you have a LiDAR iPhone or iPad Pro, it captures geometry, photos, 360° panoramas and notes in one walk-through, all positioned in space and true to scale, ready to model from. We don't guess at the geometry and we don't invent the images. Everything is captured, processed and stored on the device. Free, no account, and completely private.

Download on the App Store

Needs a LiDAR sensor: iPhone 12 Pro or later Pro model, or iPad Pro 2020 or later. No Pro iPhone? Nothing else on this page needs one. See the six ways in. Privacy policy.

How it works

Five stages, once per building. Click any stage to open it. In stage two, click the way in that matches what you already have.

Six ways in, and all of them end at the same model

Only one of them needs a scanner. Everything after this stage happens in a browser tab, and you can mix them freely: scan the ground floor, trace the architect's DXF for the first, draw the loft from a tape measure. One model either way.

Fastest and most accurate

LiDAR scan. Walk the building with an iPhone or iPad Pro and come out with measured geometry, photos and 360° panoramas, all positioned in space. One visit, everything collected at once.

The long version, on why buildings lose their information in the first place and everything a finished model produces, is on a page of its own. Picking which of the six ways in to use? See what actually goes wrong with each capture method.

Who this is for

Everybody gets the same platform, the whole of it. Scanning, browser modelling, drawing sets, the published twin, the property portal and the operations side are one product, not tiers sold to different trades. The only difference between the rows below is which part you reach for first.

Property owners The main one. You own the building, so you carry every cost of not knowing what is in it: the survey paid for twice, the site visit that existed only to measure something, the material ordered wrong, the contractor quoting from a drawing that stopped being true years ago. One accurate twin ends that. Every trade, valuer, insurer and buyer after it starts from the model. You do not need a scanner: an old floor plan is enough to start. And when you sell, the twin goes with the property, the way keys and deeds do. Start your own → Property developers Sell off-plan: a buyer explores their own unit, sees the morning light in it and picks finishes months before there is anything to visit. Then keep the same models for permit and construction drawings, handover documentation, and the operations system for the finished estate. The twin → Hotel & property operators Know what you own. Every vent, riser, fixture and finish located and specified, so a refurbishment starts without re-surveying and maintenance hangs off the objects instead of a spreadsheet nobody trusts. Building data → Designers & fit-out teams Author and share in a browser. No CAD seat, no scanning device, no render budget, and drawings that come out of the model instead of being redrawn. BIM Author → People who want to learn it A self-paced online course: reality capture, modelling, and connecting your own AI to Skanna, to set it up in your business or to digitise your own buildings. The course → Teams paying for CAD seats Cut the licence, survey and drawing-production lines, and the separate booking, service and document systems alongside them. Talk it through →

What the model gives you

Publish the finished model to a link. Anyone you send it to opens a fully rendered building in their browser, with no software, no account and no download, and everything below is already in it.

Digital twin · dollhouse view, after dark
A digital twin of a two-bedroom apartment seen from above with the roof off, after dark: rendered walls, tiled floors, a fitted kitchen, a stone feature wall, and a furnished terrace with a pool, all lit by the building's own fixtures

Sun study

Real solar geometry on the site's own coordinates. Move the time and the date, and the shadows follow.

2D drawings, in vector

Plans, elevations and sections on your title block. PDF, SVG and DXF at any standard scale.

Lighting

Every fixture is a real emitter, on its own switch, from warm white to daylight.

Walk and orbit

Drop into first person at eye height, or stay above it and turn it in your hand.

Measure anything

Two points, a real dimension, off the same geometry the drawings come from.

Click for the data

Every object carries its type, storey, dimensions and whatever the author attached: manufacturer, capacity, service dates, the manual.

Building services

Ventilation, electrical, water, drainage, gas and data as real objects. X-ray the structure to see all of it at once.

Materials the viewer picks

Offer a curated set of finishes and let the buyer restyle a room. Your published model is never touched.

Furniture and equipment

A catalogue of real products at real dimensions, placed by the viewer and cleared with one button.

Pins

A photo of how it was actually wired, a 360° panorama of the room as built, a note for whoever comes next, pinned to the surface it describes.

Property portal

Every building on its own permanent page: models, drawings, documents, media and a dated log of everything ever added.

Operations

Inventory, condition, service history and renovation progress recorded on the objects themselves.

How it compares

Skanna costs a fraction of a traditional CAD seat. This is about scope, not quality: every tool here is good at the part it was built for. The difference is that you need all of those parts to keep a building documented, and buying them separately is where the money and the contradictions go. Open a row to compare.

In use today

This is in production, not in beta.

Skanna is already on site on multiple continents, making the drawings and digital twins for housing developments, private homes, a restaurant, sports centres and mixed-use buildings. We are making a difference from the ground up, in developing markets as much as anywhere, with solutions that work on real buildings. Here are four of the jobs, and what each one started from.

One model, many jobs

A 100-unit development, and everything else the model can do

On a 100-unit development the same models give the permit and construction drawings, a buyer walkthrough of each unit, and the operations and maintenance system for the finished estate. Villas are measured on site while they are being built, so the model follows what is actually there. And the same model does the work you would otherwise buy from several other places:

  • Virtual toursWalk the building on a link, with 360° panoramas pinned where they were taken.
  • Photoreal renderingsThe images an image studio would make, rendered from the model.
  • MEPVentilation, electrical, water and drainage as real objects, for the companies that design and install them.
  • Operations and maintenanceInventory, condition and service history kept on the objects themselves.

If you make the products

Talk partnerships

For anyone who wants to build on top of Skanna and bring their own products and data into the model. Your range goes in at real dimensions with its data attached, and can then be placed in real buildings by hand in BIM Author, or by AI through the MCP connector.

  • Material calculation: quantities and take-offs straight off the walls, floors and finishes in the model
  • Custom furniture and joinery: made to measure against geometry that is actually correct
  • Materials and fittings suppliers: your range as finishes and fixtures a designer or buyer can pick
  • Furniture and appliance brands: your library of models and product data inside the model
  • Interior design-and-build and renovation firms: design, quote and build from one model, with your own catalogue in it

Bring the idea, whether it's a catalogue inside the model, a market of your own or a white-labelled tool, and we'll talk it through.

This one goes straight to me.
