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.
