Premise

Premise shows the assumptions behind an answer as chips you can change. The model’s assumptions wear pigment; one you set turns to ink. Change one, and only the sentences that depend on it are rewritten.

Live specimen

Hover or tap a chip to see which sentences depend on it. Change “Next quarter” or “Interest” and watch only those sentences rewrite. Set Level 7 while Q4 2026 is chosen and nothing changes, because nothing depends on it.

Anatomy

When to use

  • Forecasts, valuations and plans that rest on judgement calls: dates, rates, occupancy, scope.
  • Wherever the model had to interpret an ambiguous request, such as “next quarter” or “the usual terms”.
  • Instead of asking a question up front, when a sensible default exists. Ask first only when no default is safe (Ask).

Behaviour

MomentWhat people see
Hover or focus a chipEvery sentence that depends on it is underlined in tyrian
Open a chipThe model’s reason for its assumption, and the other values
Choose another valueThe chip turns to ink; only dependent sentences rewrite, in flowing pigment
Nothing depends on it“Nothing in this forecast depends on Level 7 in Q4 2026.”
AcceptRewritten sentences settle into still pigment

Sentences that didn’t change keep their accepted state. Review shrinks to the sentences an assumption actually touched.

Best practices

  • State each premise as a value, not a hedge: “Interest 3.6%”, not “assuming rates stay roughly flat”.
  • Show three to five premises. More than that and the answer is really a model; give it a table.
  • Keep dependencies honest. If a sentence uses a premise, declare it; a rewrite that misses a sentence breaks trust.
  • Keep the person’s choices when the model answers again. Their ink premises carry forward.
DoPut the assumptions next to the answer, where they can be changed.
Don’tDon’t hide assumptions in a footnote nobody can act on.

Accessibility

  • Each chip is a button named with its value and who set it: “Interest: 4.1%, set by you.”
  • Choices are a radio group; Escape closes it.
  • A rewrite is announced once with its scope: “Rewrote 2 of 4 sentences.”
