Your project notebook

Create a Curio 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.

Then use Curio’s incredible set of metadata properties to find, track, and manage it all.

A single amazing app

Curio’s intuitive environment provides a comprehensive collection of integrated tools and features so you can be more productive and stay focused on your creativity and research.

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.

It’s all in Curio.

Continuous productivity

With Curio you have an extraordinarily close connection to its development and support. In most cases feedback and requests are quickly incorporated in upcoming releases, and many support incidents are answered within hours.

This tighter feedback loop and rapid development cycle, with major releases appearing every few months, allows us to quickly react to customer requests, market trends, and competition.

Traditional licenses include one full year of free major updates so license holders and subscribers will enjoy a continuous stream of major productivity features and enhancements.

Flexible licensing

Curio can be purchased either as a traditional license or as a Mac App Store subscription.

Purchase a traditional license from our website and get one full year of free major updates. Renew your license whenever you’re ready to enjoy another free year of updates.

Or, purchase a low-cost monthly or yearly subscription from the Mac App Store and know that you’re always on the very latest release as macOS silently handles installing updates.

It’s your choice.

It’s your data

Your Curio projects can end up containing a massive amount of data.

Unlike some big web-based service solutions out there, your data isn’t in a central database tempting hackers, or inaccessible due to a service outage, or at risk of the shifting focus of a VC investor.

This is your data on your Mac.

Curio also makes it super easy to export all of your project data in plain text, rich text, markdown, PDF, various collection formats, and more.

Compositions

Introducing composition, Curio’s most powerful collection figure. Unlike other collections, this über collection is designed to contain and organize other collections!

This means normal figures like text, images, and files plus collection figures like lists, tables, stacks, mind maps can all exist within a composition collection.

Each composition is made up of one or more independent rows, with each row having one or more columns, and each column having one or more stacked figures. Simply drag-and-drop to dynamically create rows and columns.

The composition automatically lays out items, scooting and auto-spacing figures around as the composition is resized and contained figures are added, removed, and modified.

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.
