What it's for

One tool, many shapes of work

Because pages can hold live inputs, charts and databases, OpenBook fits jobs a plain editor can't.

Knowledge base

Linked notes with mentions, a table of contents and full-text structure — your second brain, offline.

Lightweight dashboards

Wire inputs to formulas to charts and you have a living model — no spreadsheet gymnastics.

Plans & trackers

A database as a board today, a calendar tomorrow, a swimlane next week. Same records.

Research notebooks

Interleave prose, data and interactive widgets; export a clean, self-contained HTML artifact.

Teaching & decks

Author once, then present the same page as a slide deck with notes and live demos.

Shared tools

Lock a group of blocks and hand teammates a read-only calculator or picker that still works.

Bring your own workflow

Start from a blank page — OpenBook bends to the task, not the other way around.
