What’s Curio?

Curio is an amazingly flexible digital notebook for storing and managing everything.

The Real World

You have work projects and home projects, school classes to manage and book reports to research, vacations to plan and novels to write, web sites to design and lab results to organize. Perhaps you currently use a collection of notebooks, your office whiteboard, scraps of sticky notes, oodles of browser bookmarks, and multiple documents scattered around your hard disk.

Basically you have a mess.

Curio Can Help!

In Curio, create a project to represent your real-world project, then fill it with everything related to that project including notes, bookmarks, images, documents, and much, much more. Use Curio's integrated lists, mind maps, tables, and index cards to organize all of this information or just place it anywhere on the page. Speaking of which, your projects can have dozens or even hundreds of pages, which we call idea spaces.

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

The best part is you are in complete control over your idea spaces. Make them sloppy or organized, freeform or in a grid, and place anything anywhere. This is called visual thinking and perfectly mirrors your real-world notebooks and whiteboards so you are instantly comfortable in Curio’s innovative environment.

Thousands of customers around the world use Curio in a surprisingly diverse range of occupations. We have students and professors, engineers and designers, lawyers and writers, entrepreneurs and filmmakers, all using Curio for information gathering, brainstorming, and creative exploration.

Curio now makes it super easy to insert a streaming YouTube or Vimeo video directly into your idea space.

Mind Map Boundaries

Curio mind maps now support colored boundary areas that enclose a parent figure and all of its children.

Easier List, Mind Map, and Table Styling

Retina Ready
