Continuum

Continuum is a local-first calculation editor for people who need to turn notes, assumptions, and models into clear results. Write structured, line-based notes and Continuum evaluates expressions in a live result rail, so changing an assumption updates the downstream calculation. It keeps the reasoning visible instead of hiding it in a spreadsheet cell, making proposals, budgets, scenarios, and everyday decisions easier to inspect and revise. Continuum also includes a companion scratchpad for quick calculations and a full workspace for deeper work. Your documents remain readable and exportable, with a calm interface designed for thoughtful, human-controlled analysis.
