Fix it
“The pipe under my sink is dripping.”
Something has broken and you would rather not pay someone.

Knack draws the answer onto a photo of your own thing — arrows on the exact screw, latch or button — and reads the steps out while your hands are busy.

On a computer?Scan this with your phone camera to open this page there.
A dripping trap under a kitchen sink: the leaking joint ringed, the nut to turn arrowed, and which way to turn it.
Drawn live on this page by the same renderer the app uses. No video, no screenshots.
Four things people point it at.
It is not only for things that are broken.
Build it
“What order do these pieces go in?”
Flat-pack, a kit, or a box of parts in the wrong order.
Use it
“I have just got this — how do I start it?”
You have just bought it and do not want to read forty pages.
What is it?
“What is this part called?”
Name an odd part, screw or symbol — and what to search to buy another.
Three steps.
Point your camera
At the thing itself. No model number to hunt for on the back.
Ask in your own words
Say it out loud or type it. Describing it badly is fine — that is the job.
Follow the drawing
One step at a time, drawn on your own photo and read out to you.
It tells you when to stop.
Knack is built to be honest about what it does not know, which matters more than being clever.
- If the job involves gas, mains electricity or the structure of a building, it says so and tells you to call a qualified person.
- If it cannot tell what it is looking at, it asks instead of guessing.
- If a step does not work, tell it. It looks at a fresh photo and finds another way in, and that never costs you anything.
Get the knack of it.
