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 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.

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.

Purchase Upgrade

Customers who previously purchased Curio 8, 9, or 10 from our online store essentially have a Professional edition of Curio since all features are available to you in that release. With Curio 11, we now offer lower-priced editions and upgrades for those that don't need some of the more advanced features, like we had prior to Curio 8.

👥 Multiple Licenses
Volume buyers should contact us to learn about multi-user discounts.

Curio’s license agreement allows you to use a single license key on multiple machines, such as a home and work Mac. However, if you have multiple users that want to use Curio, then a discounted volume license should be purchased.

Download and Installation

Curio 11 requires macOS Yosemite, El Capitan, Sierra, or High Sierra.

  1. Start by downloading Curio then drag Curio from your browser’s Downloads folder to your Applications folder to install.
  2. Launch Curio to begin your 2-week trial with all Professional features fully enabled and available. Our bundled Welcome to Curio guided tour will automatically open showcasing Curio’s major features. It also includes the complete user documentation and a gorgeous sample gallery showing off what you can create in Curio.
  3. Purchase and enter a Professional, Standard, or Core license key based on the features you need and Curio’s interface will dynamically change to reflect that edition’s features. You can even start with one edition then move up to a more feature-rich edition by purchasing a crossgrade license.

Once the trial expires, you can request an extension to your trial if you wish, otherwise Curio will enter into a simplified Reader mode, allowing you to continue using Curio for read-only browsing, printing, presenting, and exporting of Curio project files and contents. At any time you can still purchase and enter a license key to enable functionality. Friends and colleagues that don't own Curio can take advantage of Reader mode to view projects you share with them.
