What can Curio do for you?

In Curio, create a project to represent a real-world project that you’re working on. Next fill it with everything related to that project including notes, images, PDF’s, documents, web links, multimedia, and much, much more.

You can place this information anywhere on Curio’s freeform idea spaces. Or use Curio’s integrated mind maps, lists, tables, index cards, albums, pinboards, and Kanban-style stacks to organize your data into powerful collections.

Anything placed into Curio can be associated with meta data such as tags, flags, checkboxes, priorities, ratings, resources, and start/due dates and durations for easy searching and task management.

And, now in Curio 14, your project can include a daily journal for meetings or class notes, all neatly organized and sorted automatically.

The key point is that everything related to your project is stored, managed, and tracked within a single project file using a single, well-integrated application. You’re not juggling a mess of files scattered about your hard disk with a disparate suite of apps.

We invite you to join the thousands of customers around the world who use Curio for information gathering, brainstorming, and creative exploration.

What’s New in Curio 14

An amazing suite of new functionality so you can be even more productive.

indicates a feature only in Professional indicates a feature only in Standard

Requires macOS Mojave, Catalina, or Big Sur on Intel or Apple silicon.

macOS Big Sur Enhancements

Curio 14 has been updated for macOS Big Sur!

  • Curio now supports local PDF generation of math equations for instant renderings.
  • Grab Web Archive functionality so you can right-click on a web link figure and archive the site as either a paginated PDF, a single large PDF image, or a web archive file.
  • Organizer web view support for a find bar (⌘F) to search for text within that web page.
  • Support for macOS Big Sur's new unified toolbar style.
  • Numerous interface tweaks for better macOS Big Sur compatibility.

Native Apple Silicon Support

Curio 14 is now compiled as a universal binary to natively support the new Apple silicon Macs, as well as existing Intel Macs!


Curio's new integrated journalling feature allows you to log meetings, make class notes, keep a journal or diary, and much more! All neatly organized, sorted, and managed by Curio with automatic year and month groupings.

Curio comes bundled with several journal templates plus it's incredibly easy to create your own.

You can append a custom title to your Journal entries, which comes in handy if you have multiple entries for the same day, like entries for multiple meetings or classes, or for periodic "Weekly" or "Quarterly Goals" entries.

Your journal entries can contain anything a normal idea space can contain including text, markdown, images, links, mind maps, lists, videos, etc; checklist tasks, GTD-style tagging, start/due dates, etc; links and references within your project or between projects...

And, since the journal is a part of your project document, it's always accessible and integrated with the rest of your project. Now all your notes, research, brainstorming, and more are all organized together more effectively in one complete document package for easier tracking, storage, and archiving.

Table of Contents

You can now insert a Table of Contents as a native Curio list or mind map collection which dynamically updates if changes are made to your project's Organizer hierarchy.

The collection is comprised of idea space link figures, displayed in icon mode, to all Organizer items after the idea space that contains the Table of Contents itself.

Clicking a link will jump to that idea space in your project. If you export your project as PDF, then clicking a link in the exported Table of Contents will jump to the appropriate page within the PDF.

You can use any list or mind map style to change its look, and fine-tune its contents using the new Table of Contents inspector popover.


Professional customers now have a much more sophisticated layers popover providing new capabilities.

Drag and drop ordering, locking and visibility, and new restrictions such as hiding certain layers when printing or presenting, along with interactions such as swipe to delete make it easier to work with figure layers.

In addition, new idea space and presentation mode context menus allow you to easily move figures to specific layers and hide or show layers during presentation mode.

Automatic Figure Spacing

At long last, by extraordinarily popular request, Curio can now automatically scoot figures down or up as figures above change size!

For example, adding, changing, or removing items from a list can now move figures below the list either down or up... automatically!

And this automatic shifting of figures can automatically propagate down the page as figures bump into, or pull back from, figures underneath.

The new text figure minimum height feature, mentioned below, can assist with laying out auto-spaced forms.

Improved Spread PDF

You can now spread selected figures across the idea space, then down the idea space, creating a collection of columns and rows, each showing a different page of the PDF. You also have control over the spacing or gap between the columns and rows.

The result is a matrix of PDF pages for you to annotate and take notes on.

Markdown Refinements

Markdown lists now render with more accurate alignment of list numbers and spacing due to more precise prefix calculations and more consistent line spacing, regardless of font size or style.

In addition, the markdown renderer adds new support for unindented lists for lists without titles.

Plus contents of markdown code blocks will now ignore symbols that may look like markdown syntax.

Perfect Circles

A new circle base shape allows for easier construction of certain figures and opens up possible styles such as the new Circles mind map org chart.

Figure Enhancements

Numerous figure enhancements such as completed tasks displayed with strikethrough and dimmed; neumorphic shadows; automatically updated Idea Space Link Figure titles and faster preview renderings; personal figure styles can now include default sizing; image alias icon overlays; and lots of other improvements.

Collection Figure Enhancements

Tons of collection figure enhancements such as automatically adjusting table row heights as contents are changed; table cell margins; "transparent" selection mind maps; shortcuts to expand/collapse mind maps and lists; easy parent node creation; and lots more!

Scribble Enhancements

Curio's sketching tools now has a new enhanced color picker with a much better spread of hues on the inspector shelf and inspector bar.

Enjoy fantastic new support for tablet scribbling via an iPad connected to the Mac using Catalina's Sidecar feature. Sketching using your iPad with Curio's pressure-sensitive brushes and pens is now much more comfortable and easier to customize.

This combination of Mac+iPad+Pencil via Sidecar really is a wonderful way to sketch directly into Curio, without having to purchase a dedicated graphic tablet.

DEVONthink Integration

The Local Library shelf now supports searches for DEVONthink data via Spotlight, instead of our old Sleuth-based technique with required DEVONthink Pro Server.

That's right: the normal DEVONthink product will suffice; DEVONthink Server is no longer required!

Masters Enhancements

Master templates now include support for custom inner figure stylings. This means any figures within a collection, such as these stylized table header cells, remain intact and continue to reflect the custom stylings of those inner figures from the master even if the figure content is changed.

Plus Much More

  • Text figures now support a minimum height which is useful for forms, templates, or in combination with automatic figure spacing.
  • Better integration with the popular Hook productivity app is now possible thanks to new Curio AppleScript capabilities.
  • Curio adds a new Paste As > Rich Text menu which is especially useful when pasting from Microsoft Word.
  • Curio's MindManager mind map import/export support now handles hyperlink figures, and fixes an export compatibility issue.
  • New variables for an asset file's creation and modification which is useful in captions.
  • Import/export/printing improvements including a project file path variable, an idea space count print header/footer variable, and PDF export refinements.
  • Organizer and idea spaces enhancements such as zooming both split views simultaneously; sorting idea spaces by descending title; new Organizer headings and font cleanup.
  • Copy As Hyperlink can now encode deeper link information about the selected figure, including selection range in a text or PDF figure, or starting playback time in a media file.
  • HTML and Image Export will now export high resolution Retina images for much sharper images.
  • Curio Standard now includes Automatic Backups, which was formally a Pro-only feature. (Pro supports per-project backup customizations.)
  • Major performance and technical improvements including much faster rendering of image figure previews.
  • An insane number of code updates to better support Apple’s latest macOS releases.
  • Plus dozens of other miscellaneous optimizations, tweaks, and fixes.

Meet Curiota!

Curiota is our free, out of the way yet always available menu bar app that allows you to quickly jot down ideas, take notes, or collect files when inspiration strikes.

You can also send text or files into Curiota via macOS Services, the macOS Share button, the print dialog’s Save PDF to Curiota option, a browser bookmarklet, and even AppleScript.

While Curiota can be used even if you don’t own Curio, when combined with Curio you have a powerhouse combination since Curiota helps you collect notes and files outside of Curio. Then, when you’re back in Curio, you can view, search, and access all your collected Curiota information directly using Curio’s Library.
