About Curio

Copy freely — these blocks are written to be pasted straight into an article.

Short description (one paragraph)

Curio is an intuitive, freeform notebook environment for macOS. Create a project to represent a real-world project, then fill it with everything related to that project — rich text and Markdown notes, images, PDFs, documents, web links, and multimedia — placed anywhere you like on Curio’s freeform idea spaces.

Standard boilerplate (three paragraphs)

Curio is an intuitive, freeform notebook environment for macOS. Create a project to represent a real-world project, then fill it with everything related to that project — rich text and Markdown notes, images, PDFs, documents, web links, and multimedia — placed anywhere you like on Curio’s freeform idea spaces.

Integrated collections such as mind maps, lists, tables, index cards, albums, pinboards, stacks, and Kanban boards organize that material when structure helps, and extensive metadata — tags, dates, priorities, ratings, checkboxes, percent complete, and custom data — makes all of it searchable and trackable.

Every Curio project is a single local file on your Mac. Nothing is uploaded to a remote service, nothing requires an account, and your work stays readable and exportable on your own disk.

Background (context and history)

Most note-taking apps ask you to choose a shape before you start: an outline, a document, a card, a canvas. Curio doesn’t. A Curio idea space is a freeform canvas where a paragraph of text, a scanned handout, a mind map, a table of lab results, and a to-do list can sit side by side, positioned however the work actually makes sense to you.

Curio has been developed continuously by Zengobi since 2004 and has a famously eclectic customer base: designers gathering inspiration and client requirements, writers brainstorming plot and character development, students taking notes and annotating handouts, professors building and presenting lesson plans, scientists collecting lab results, project managers tracking feature checklists, lawyers preparing cases, and entrepreneurs mapping out new companies.

Curio 34 adds Kanban boards that generate their own sorted stacks from any grouping you choose, Excel-style table formulas, project-scoped tag sets, paragraph and character text styles, macOS widgets, Shortcuts support via App Intents, and — for Curio Pro sustainers — the new Curio CLI and its built-in MCP server, which give Terminal scripts and AI agents direct, structured access to Curio projects.

Key Features

What Curio does

  • Arrange anything anywhere on freeform idea spaces.
  • Build mind maps, outlines, lists, tables, index cards, albums, pinboards, stacks, and Kanban boards.
  • Work with rich text and Markdown, images, PDFs, documents, web links, audio, video, equations, and diagrams.
  • Spread a PDF across idea spaces to annotate and take notes page by page.
  • Track work with tags, tag sets, checkboxes, priorities, ratings, resources, and start/due dates.
  • Connect ideas with wikilinks, backlinks, deep links, and cross-references.
  • Find what you need with fast, relevance-ranked search, fuzzy matching, and query-based collections.

Why Curio

  • One integrated workspace. Brainstorm, research, plan, write, and present without scattering your work across unrelated apps.
  • Local-first and offline-ready. Your projects are files on your Mac, under your control.
  • Flexible and visual. Start with a blank canvas, or use built-in collections, templates, and styles to give ideas structure.
  • No lock-in. Extensive import, export, and printing options keep your work usable elsewhere.
  • Made for deep work. Researchers, writers, students, educators, designers, project managers, and engineers use Curio to develop ideas, collect sources, plan projects, take class notes, prepare presentations, and track work.

What’s New in Curio 34

The headline additions. The full release notes cover dozens more improvements and fixes.

Kanban Boards

A new collection type that automatically generates sorted stacks from a grouping you choose — priority, rating, tag set, or dates like start, due, and last modified. Drag a card between stacks and Curio updates the underlying metadata to match its new home.

Smart Kanban Boards Pro

Curio Pro backs a Kanban board with a search query, pulling matching figures from anywhere in the project into synced instances that stay live with their originals.

Curio CLI and MCP Server Pro sustainers

A separately installed curio command line tool that opens Curio to Terminal users, shell and Python scripts, AI agents, and MCP hosts like Claude Desktop — querying, reading, and updating figures, importing and exporting content, and navigating projects. A perk for Curio Pro sustainers.

Table Formulas Pro

Table cells accept Excel-like structured reference formulas using column names rather than A1-style references, with current-row ([@Column]) and whole-column ([Column]) references plus the usual math and text functions. Rendered Markdown tables support them too.

macOS Widgets

Status and Query widgets bring Curio tasks and query results to the macOS Desktop and Notification Center. Click any item to open Curio and jump straight to it.

Shortcuts via App Intents

Native Shortcuts actions for opening projects, finding items, reading the current selection, navigating to results, and exporting or importing content — automation without touching a command line.

Synced Collection Instances Pro

Copied lists, mind maps, and stacks mirror their source, keeping item content and metadata in sync across idea spaces.

References Panel Pro

Attach typed references to any figure using Curio jump targets or web URLs from the clipboard, building a cross-reference layer over a project.

Project Tag Sets

Tag sets can now be scoped to a single project while keeping colors, ordering, and Kanban grouping support.

Paragraph and Character Text Styles

Project-wide paragraph and character styles that update matching rich text and Markdown across the project, joined by new kerning, line height, and paragraph spacing controls.

Flexible Adornment Positions

Checkboxes, tags, dates, priorities, and ratings can be placed at any of twelve positions around a figure, with checkbox adornments optionally separated into their own aligned margin.

Word Count and Readability

A Word Count status bar module shows live selection metrics with a detailed popover covering readability and sentiment, including Flesch-Kincaid and Gunning Fog.

Pricing and Availability

Curio is sold two ways: a one-time license key from our website, or a subscription from the Mac App Store. Both unlock nearly identical feature sets. All prices are US dollars.

License keys (zengobi.com)

EditionNew licenseAcademicUpgrade
Curio 34 Professional $119.99 $99.99 from $79.99
Curio 34 Standard $99.99 $79.99 from $59.99

A license key is a one-time purchase that includes a full year of free major and minor updates. Curio doesn’t expire when that year ends — it simply stops receiving updates until the license is renewed. Crossgrades and volume discounts are available, with an automatic 20% discount on quantities of 20 or more. See the License Key FAQ.

Subscriptions (Mac App Store)

EditionBilled yearlyBilled monthly
Curio Professional$6 / month$8 / month
Curio Standard$5 / month$6 / month

Apple handles billing and renewals, and all updates arrive automatically. Academic and volume discounts aren’t available on subscriptions. See the Subscription FAQ.

Trial and free mode

Curio starts a 2-week trial with every Professional feature enabled, and opens the bundled Welcome to Curio project on first launch for a guided tour. When the trial ends without a purchase, Curio keeps working in free mode with the Standard feature set and projects of up to five idea spaces; larger projects open read-only for viewing, exporting, and printing.

Curio CLI and MCP

The Curio CLI is a separate, free download for Curio Pro sustainers, distributed and updated independently of the main app so protocol and security updates can ship on their own cadence. It works with both the website and Mac App Store editions of Curio. See the Curio CLI documentation and CLI release notes.
