The ledger calculates. Code writes.

Your question becomes a checked query, and code writes the answer from recorded data. A model may only help read the question.

A question goes in as a sentence, and comes back as an answer with the records and dates it covers.

Understand: code first

The question becomes a query

What is being measured, how it is grouped and over what period. Code does this first. If it cannot, a model may propose a plan, using only names in your records. Checked before anything runs.

Calculate: no model involved

The query becomes figures

It runs over your own reconciled records. Every figure, row and piece of evidence in the answer comes from this step.

Explain: code writes it

The figures become a sentence

Code writes the answer from the figures. No model sees the result or writes a word of it.

Every answer shows its math.

Code writes every answer from the computed figures. A model never writes one.

How it is enforced →

Ask in the product, or through our MCP server.

One set of figures, read-only everywhere.

  1. In the product

    From any screen.

    Press ⌘K on any screen and ask. The answer comes with the figures it was worked out from, and a link to the rows behind it.

  2. In your editor

    From Claude Code and Cursor.

    Add our MCP server with one read-only key. An agent can read every figure and change nothing. The key does not expire; replace or delete it.

  3. In Claude

    From Claude, Cowork and the desktop app.

    Add our MCP server as a connector and sign in. The connection is yours, read-only, for one organization. It ends after 30 days without use.

Ask, understand, act.

Connect one source and ask the first question.

No prompts or replies by default · Checked against your bills

Every answer comes from the ledger your teams use, and opens the screen where you approve or reject.
