AI extraction analysis
The curve, the verdict, and the cause. Channelling, erosion and early flow named rather than hinted at.
AI powered espresso
Brew better.
Powered by AI.
Every espresso tells a story. CAFFYX reads the dose, the yield, the curve and the taste, then tells you the one thing to change next.

AI Coach
It does not hand you a dashboard. It hands you one instruction.
Ten numbers you have to interpret is homework. The coach reads them, commits to a change, and tells you what it expects to happen.
Say hello
Coach, this morning
ExampleEvery line is drawn from your own shots, never a generic tip.

Watch the shot think.
Pressure, flow, weight and temperature, plotted while the pump is still running. Scrub it and see exactly where a shot goes wrong.

Preinfusion that matters
A slow, low-pressure start is where channelling is prevented, and where most logs stop looking.
Flow tells you first
Flow climbing while pressure falls is the puck eroding. You can hear it too late; the curve says it at 12 s.
One number to keep
Ratio and time in one line. Everything else is evidence for the one change the coach asks for.
Everything in the box
Nine things it does. One thing it is for.
Every screen exists to answer the same question: what do I change on the next shot?

Pressure profiling
Preinfusion, ramp and decline as a shape you can compare, save and pull again.

Statistics
Weeks, months and the slow curve of getting better. Trends you cannot feel day to day.
Designed for people who care how it tastes.
Grind, distribute, tamp, pull, taste. CAFFYX does not change the ritual. It remembers all of it, and notices what you cannot.
How it works
One week from lucky to repeatable.
Nothing here needs a refractometer or a new machine. It needs four taps a morning.

Three shots is enough of a pattern. It asks for one step finer, and says what to expect.

Same beans. Same machine. Different spread.

Illustrative. Your own numbers are the ones the app plots.
Your setup
It fits around what you already have.
No new machine, no subscription hardware, no brand you have to buy into.
Any espresso machine
The log does not care what pulls the shot. Lever, pump, or a machine older than you are.
Bluetooth when you want it
Pair a scale and the weight, flow and timer stream in live. Everything still works without one.
Installs like an app
Add it to the home screen and it opens at the machine, offline, in under a second.
