Indoor navigation from a PDF floor plan.
Upload the plans you already have and Wayfinder turns them into a building people can navigate on their phone. No beacons. No hardware. Nothing to install in the building.
Viewing is free and unlimited — you just need an invite from whoever manages the building.
01 The problem
Printed signs stop at the lift lobby, the room numbering made sense to whoever laid it out in 1974, and the answer to "where is Meeting Room 4?" is usually a receptionist pointing down a corridor.
The fix on the market is beacons: buy the hardware, install it on every floor, maintain the batteries, repeat in the next building. Most estates never get past the quote.
Wayfinder needs a PDF.No beacons · No hardware · No site survey
02 How it works
Drop in the vector PDFs you already have, one per floor. No CAD licence, no data prep, no site survey.
Walls, rooms, doors, stairs and lifts are pulled straight out of the PDF and wired into a navigation graph. No tracing by hand, no per-floor fee.
Invite your people and they're in. It opens in a browser: no app store, no rollout, and no charge for anyone who's only looking.
03 What it does
Extraction
The extraction pipeline does the work everyone else quotes you for. One floor of this building came back as 105 rooms, 207 doors, 11 staircases and 20 lifts, and every one is reviewable before it goes live.
Live position
Each floor is pinned to real-world coordinates once, so GPS and the phone's motion sensors work together and keep a position where GPS alone gives up. Rotate the map to your heading, or keep it north-locked and rotate the arrow.
3D view
The floor renders in 3D with walls, corridors, rooms, doors, stairs and lifts as separate layers, so you can switch off the clutter and get your bearings.
Compound sheets
Big floors usually arrive as a pile of separate drawings. Drop them in, line them up, crop the overlaps, and Wayfinder composes one floorplan.
Geo-calibration
Drag the plan onto the map, scale it to the building and rotate it to true north. From then on the building knows where it is in the world, which is what lets a phone's GPS put someone on the right corridor.
Search for a room and get a route across floors, via the lift or the stairs, with distance and walking time. In beta while we sharpen extraction on messier plans.
Find a room, office or department by name or room code, and go straight there.
Smooth touch and mouse zoom, enough to read the small print on a plan.
Installs as a web app and caches the plans you've opened, so a patchy basement signal doesn't take your map with it.
Floors switch with a tap, and on handsets that report altitude reliably, Wayfinder can pick the floor for you.
04 For estates teams
Belong to as many organisations as you need, with a role in each. A Control Panel governs who can author, who can invite, and who can only look.
Every invite names the organisation it's for, so nobody has to guess which building they've just been added to.
An organisation owner runs their own tenancy and can export their data whenever they want. No hostage-taking.
Plans and data are held in Microsoft Azure UK South. It's in section 13 of the Terms, and it's the second thing every buyer asks.
05 Pricing
Unlimited floors, unlimited authors, unlimited viewers. Free, and it stays free.
Get Started FreeBilled on your peak building count for the month. Cancel any time: no contract, no minimum term, no sales call.
Add a BuildingRoll it out to a thousand staff and visitors for nothing. The only paid seat is the person who uploads the plans.
You pay for the buildings you have, and the price is smooth all the way up.
If a subscription lapses, buildings lock rather than vanish. Pick it back up and everything is where you left it.
06 On the roadmap
The route already exists; what's coming is the written version. "Left out of reception, lift to floor 3, second door on the right."
Marked locations for receptions, lifts, toilets, meeting rooms and other key facilities.
Lift-only routes for anyone who can't take the stairs, and a route that says so before you set off.
Let your team annotate the floorplans together: notes, markup and corrections on the plan itself, not in an email thread.
07 Why Wayfinder
No beacons, no anchors, no batteries, no contractor on site. The install is a PDF upload, so the second building costs the same effort as the first.
Wayfinding only works if everyone has it. Charging per user would guarantee it never got used, so we don't.
Held in Azure UK South, exportable on demand, and locked rather than deleted if you stop paying.
08 Questions
No. Wayfinder positions people using the phone's own GPS and motion sensors against your floor plan. There is nothing to buy, install or maintain in the building.
Automatic extraction needs vector geometry — it reads the actual lines and text out of the PDF, which a scanned image doesn't have. A scanned plan can still be displayed and navigated, but the rooms, doors and routes have to be set up rather than detected. If you're not sure which sort you've got, send one over and we'll tell you.
They need an invite from whoever manages the building, and that's it. Viewing is free and unlimited — there's no per-user charge, ever.
It installs as a Progressive Web App and caches the plans you've already opened, so you keep your map when the signal drops. Loading a building for the first time needs a connection.
Buildings over your free allowance lock. Nothing is deleted, nothing is overwritten, and everything comes straight back when you resubscribe. Your free building carries on as normal.
Only people your organisation has invited. Buildings belong to an organisation, roles control who can author and who can invite, and nothing is public by default.
