Cook naturally.
Jef keeps track.

Jef follows one real cooking session from first chop to last plate — and interrupts only when interrupting is worth it. The messy parts are the point.

  • spaghetti
  • pecorino, grated fine
  • black pepper, cracked
  • reserve a mug of pasta water

don’t forget this one!!

1.0 · observe

It watches your work surface.

One overhead camera and one microphone turn the session into timestamped evidence: what moved, what went in the pan, what you asked. Nothing more than the session, and never without the recording light.

Camera above, evidence below.

camera sits about 40 cm up — sees the whole board, not just the pan.

2.0 · understand

It keeps one world state.

Evidence is reconciled with your plan into a single persistent state: vessels, ingredients, heat, timers, ambiguity, hazards. When you correct it, the correction is appended, not rewritten.

when it’s unsure, it asks — and you fix it in a word.

3.0 · intervene

It speaks when it counts.

Timers and measurements are owned by deterministic code, not guesses. Jef talks when the expected value of interrupting is high: a timer, a likely mistake, a safety risk. Otherwise the kitchen sounds like cooking.

One session, one interruption.

twelve minutes means twelve minutes. a timer is a promise.

notes from one session

00:00:00 · session started

00:03:12 · pan on heat, high

00:06:48 · butter added to pan

00:09:30 · timer set, 6 min

00:15:56 · asked “how long now?” — answered

00:18:20 · timer done, spoke once

and then it shut up and let me cook.

Where this goes.

Software first. Hardware only where measurement earns its place: one camera above the bench today; a probe, a scale, and a thermal view when they make Jef more honest.
