The useful kind of simple

Write the thought.
Keep the model.

Variables stay readable. Consequences stay attached. When one assumption changes, everything downstream can answer back.

01

Write naturally

Mix named assumptions, percentages, rates, currencies, and ordinary expressions in one calm document.

remaining = income - expenses
02

See every result

The result rail keeps each consequence aligned with the line that produced it.

03

Follow the impact

Change one root value and Continuum highlights the dependent values that moved with it.

A real workspace, not a widget

Calculations deserve somewhere to live.

Organize documents and folders, search at keyboard speed, keep reusable assumptions, archive old work, and export a backup when you want one.

  • Autosaved local documents
  • Folders and shared variables
  • Quick search and archive
  • Explicit JSON backup and restore

Local-first by design

Your model is not content for someone else’s cloud.

No account

Open the workspace and begin. There is no sign-up wall.

Local documents

Calculations, folders, settings, and quick drafts stay in the current app data store.

Explicit movement

Browser and desktop data stay separate. Backup and restore only when you choose.

Honest boundary

Analytics and submitted feedback are documented separately from calculation data.

A few honest answers

Before you begin.

Is Continuum a spreadsheet replacement?

Not for every table. Continuum is for the moment when you want to write an assumption, connect it to another, and understand the consequence without building a grid first.

Where are my calculations stored?

Documents and settings stay in the current browser or desktop app data store. There is no account or cloud synchronization in the current build, and backups are files you create explicitly.

Does the live demo save anything?

No. The embedded demo evaluates what you type inside that page and does not create a Continuum document or write to workspace storage.

Can I download Pocket Scribe?

The Apple Silicon macOS companion is a working unsigned alpha, not a signed public download yet. The browser workspace is the immediate way to try Continuum.

The next thought is yours

Give the numbers
somewhere to answer.

Start with one assumption. Continuum will keep up.
