Sketch in. Block diagram out. Before your coffee goes cold.

Patchdraft turns the scribble on the case lid into a standards-based AV block diagram — title block, cable list, bill of materials, PDF. For people who patch faster than they document.

A hand sketch of a theatre setup on the left, the block diagram generated from it on the right — The scribble on the left, the plan it produced on the right — 6 devices, 7 connections, passed the check with no findings. Made on 16 Aug 2026, no Photoshop, no retouching.

Start free — 300 patch tokens on the house

For live event technicians, AV integrators and anyone who still owes the building a plan at 2 a.m. Per IEC 61082-1 and DIN EN ISO 5457.

The show went fine. The plan? Still in your head.

Rig is up, soundcheck done, client happy. The documentation is a sketch on the back of the rider, the only person who knows the cable numbers is the stagehand who’s on another gig tomorrow — and at the next changeover somebody gets to guess it all again. You know the drill. So do we.

Three steps. One PDF. No Visio evening.

Say it or show it

Type three sentences or photograph the sketch. Devices, sockets, cables — the way it’s actually patched, not the way the catalogue would have it.
Give it a once-over

Patchdraft proposes the graph, you nod or correct. Nothing reaches the PDF that you haven’t seen. The AI proposes, you have the last word.
Export, move on

Layout, sheet size and cable routing aren’t done by a language model but by code that draws the same thing every time. Out come title block, cable list, bill of materials, PDF — and DXF for the electrical planner who needs it “in CAD”.

Not a mockup. Real plans, real cables.

These aren’t design templates. They’re exports exactly as they come out of the app. No make-up.

Block diagram stage to FOH — Stage to FOH over a Dante stagebox. From a hand sketch, two minutes.

Block diagram video path with SDI matrix — Video path with an SDI matrix. The fibre run was not in the sketch — only the margin note “projector is 80 m away”. That was enough.

Block diagram meeting room with ceiling array and DSP — Meeting room. The sketch wired the ceiling array straight into the DSP — which only has analogue inputs. Patchdraft inserted a Dante switch and a converter instead of just drawing a line.

Free account. Free company. You pay when the app does the work.

Patch tokens count every job the app does for you: a drawing 15, a PDF 3, a follow-up question 3. A demo account starts with 300 patch tokens — on the house, no expiry, no credit card. In a company, everyone draws from one shared pool that the company admin allocates.

Tier	Price	Patch tokens	Plus
Demo	CHF 0	300 PT, one-off	PDF with watermark, no list or DXF export
Starter	CHF 5/month	450 PT/month	All exports, no watermark
Pro	CHF 10/month	1,100 PT/month	Your own devices from a description, your logo in the title block
Studio	CHF 30/month	4,000 PT/month	For companies: one pool for everyone, allocation per member
Enterprise	on request	agreed	We set up style and title block, invoice instead of credit card

Top up

Pack	Patch tokens	Price
Small	500 PT	CHF 6
Medium	1,500 PT	CHF 15
Large	5,000 PT	CHF 45

Packs don’t expire. A typical plan (three drawing rounds, PDF, cable list) costs around 55 PT — roughly 55 Swiss centimes. Less than the gaffer tape you’ll burn through the same night.

Straight talk, before you ask.

Doesn’t the AI just draw nonsense?

Sometimes. On odd setups it proposes the wrong thing. That’s why it only produces the graph, and you have the last word before anything reaches the PDF. Coordinates, cable routing, numbering: that’s code, not gut feeling.

My device isn’t in there.

Could be. 621 devices with 9,358 ports is a good start, not a manufacturer catalogue. You add your own devices from a description, and they stay in your library. Nobody who has ever maintained a library promises full coverage.

And my data?

Your description and the drawing are sent to the Anthropic API for processing — that’s the part that thinks. They are not used to train models. Server location, encryption and the data processing agreement are in the privacy policy, before you sign up — not in the fine print.

What if I cancel?

Then you take your plans with you. PDF and raw data are yours and stay downloadable. No lock-in, no drama.

I already have Visio.

Keep it. Patchdraft doesn’t replace the drawing tool, it replaces the hour of grunt work after it: cable numbers, legend and bill of materials from one sentence — consistent, every time.

Standards we measure ourselves against

IEC 61082-1 — cross-references across sheets
DIN EN ISO 5457 — sheet grid
ISO 13567 — layers
IEC 81346 — reference designations
DIN EN ISO 3098 — minimum lettering size

Oriented on, not certified to. The difference is spelled out in What Patchdraft is not.

Next plan: before your coffee goes cold.
