## Definition

Information Operating System is the self-applied tagline for [GalaxyBrain](https://galaxybrain.com/), a local-first knowledge workspace where every page carries variables, formulas, and live cross-references. It sits between a note app, a wiki, a spreadsheet, and a task manager — structure and computation are built into the page, not bolted on.

The framing resurfaced on April 20, 2026 with a [Show HN relaunch](https://news.ycombinator.com/item?id=47833268) from creator Jon-Paul Wheatley. The new build stores everything as local JSON, ships a built-in HTTP API and MCP tool so Claude Code, Codex, or a local model can read and write the same folder, and runs as a single-HTML-file browser app with no account.

## Example

A user keeps one page per project with custom variables like `status`, `deadline`, `budget`. Those values auto-propagate into dashboard pages — change `budget` anywhere and the quarterly roll-up updates in real time. An agent pointed at the same folder via MCP can read the structured fields the same way the human does.

## Analogy

A spreadsheet you can write paragraphs inside, where every cell is also a page and every page is also an API.

## Why it's emerging now

Jon-Paul Wheatley relaunched GalaxyBrain on April 20, 2026 with the same 'information operating system' tagline plus a new MCP tool and HTTP API, pitching it as a shared local workspace for humans and coding agents like Claude Code or Codex.
