Bidirectional binding

A debugger for spreadsheets, not a set of arrows

Excel's native tracer draws lines on top of the grid. Deckary turns the formula itself into the inspection surface — every input is a colored chip wired to a numbered row, with its live value next to it.

  • Numbered chips

    Every input is a colored chip in the formula

  • Live aggregates

    See each input's contribution in tabular numbers

  • Drill 3 levels

    Walk nested chains, breadcrumb keeps you oriented

  • Inline diagnostics

    Volatiles, errors, external refs flagged in place

Risk surfacing

What you reach for it for

The tracer earns its keep on the workbooks you didn't build, the formulas that don't add up, and the audits you have to ship — surfacing every risky pattern in the formula card itself.

  • Inherit a model

    Learn an unfamiliar workbook in minutes

  • Debug a wrong number

    Spot the input that's off at a glance

  • Pre-ship audit

    Catch hardcodes and volatiles before you send

  • Read a long expression

    Tokenized formulas beat the formula bar

Tracer vs. arrows vs. dedicated audit suites

Excel ships with arrows. Inquire and Macabacus ship with audit panels. Deckary ships with the binding between formula and data.
