Curio 18

Productivity powerhouse.

Take notes. Organize files. Collect research. Brainstorm in mind maps. Track tasks with a to-do list. Drop in an equation. Sketch out an idea. Get more productive! Curio’s intuitive, freeform notebook environment provides all the integrated tools you need to be more productive and focus on getting things done.

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

Continuous Updates

Beginning with Curio 15, instead of massive annual releases we’re shifting to a continuous stream of major releases appearing approximately every 1-3 months.

To support this change, Curio 15 and above traditional licenses now include a year of free major updates!

This change will promote a tighter feedback loop with customers and allow us to react to new ideas, market trends, and competition much more easily and rapidly.

Curio subscribers and those with traditional licenses will enjoy a new constant stream of productivity features and enhancements!

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 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.

Available as a traditional license or a low-cost subscription, begin your free, 2-week trial with our Welcome to Curio guided tour to learn how you can be more productive with Curio.

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.
