Everything OpenBook does

One calm surface, a lot of range

A familiar block editor at its core — and a kit that turns pages into living, interactive documents.

Headings, lists, to-dos, quotes, callouts, code, tables, columns, toggles, tabs and groups.

Sliders, steppers, inputs and formulas that publish named values across the page.

Write an expression over your inputs; it recomputes the instant anything changes.

Line, bar, pie, scatter and funnel charts that read live data from the page.

Typed columns, relations, filters, sorts and groups — no query language needed.

Table, board, gallery, calendar, swimlane and map over the same records.

Turn any page into a slide deck with a presenter console and speaker notes.

A review layer: humans (and AI) suggest edits that you accept or reject.

CRDT-native collaboration that merges cleanly across tabs, people and devices.

Full speed offline. Your data lives on your device; sync is optional.

Lock a group of blocks to share it as a read-only, still-interactive widget.

HTML, PDF and Markdown — including self-contained interactive HTML.

See it in motion

The home page has the real editor embedded — drag a slider and watch a chart recompute.
