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.

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.

You’re juggling it all, but organizing this information should be easier.

A Better World!

In Curio, create a project to represent your real-world project, then fill it with everything related to that project including notes, images, documents, web links, and much, much more. Use Curio’s integrated collections, such as lists and mind maps, to organize all of this information or just place it anywhere on Curio’s freeform 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—this is your project notebook. This is called visual thinking and perfectly mirrors your real-world notebooks and whiteboards so you are instantly comfortable in Curio’s intuitive 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 for Note Taking

The most flexible notebook you’ve ever used.

We call Curio’s innovative pages idea spaces—a perfect blend of notepaper, whiteboard, and sketchpad. You can type anywhere, sketch anywhere, and drag-and-drop anything to your idea spaces making it a perfect tool for note taking and research gathering.

Curio for Brainstorming

The ultimate brainstorming and idea development environment.

Curio’s tightly integrated brainstorming tools are the perfect complement to its notebook interface. Since these tools are built-in, you don’t have to purchase another application to expand on a thought or idea.

Mind Maps

Mind Maps

Curio’s full-featured mind mapping functionality includes styles, stencils, branch coloring, relationship lines, and Mindjet & iThoughts importing and exporting. Curio supports radial, left, right, org chart, top-down, and bottom-up mind map arrangements. You can even use Curio’s integrated presentation mode to present your brainstorms for all to see.



Here we’ve added a Curio list to keep track of a client’s objectives. Curio supports simple styled lists and more complex hierarchical lists with checkboxes, percent complete and due date calculations, and other meta information. Curio’s lists include full support for custom numerical or bulleted prefixes plus OPML importing and exporting.

Idea Graphs

Idea Graphs

Create fast connected idea associations when you need more flexibility than a mind map offers. With just a click, you can create instantly connected shapes with directional, bidirectional, or unidirectional lines.



Insert gorgeous styled tables with full support for row and column headers and footers. Import and export table information via CSV or copy/paste from Excel or Numbers. Since table cells are simply figures, they can include any meta information including ratings and notes.

Index Cards

Index Cards

Many authors and writers prefer to use index cards to organize their information. Use one of the many bundled styles or create your own. Create a stack of index cards and spin through them using your scroll wheel to find your best ideas.



New in Curio 9 is the photo album collection. Quickly create collections of photos or other assets with or without captions. Curio includes several album and image styles to make your collections really stand out.



Also new in Curio 9 is the pinboard collection. When you picture a group brainstorming session you see whiteboards filled with sticky notes arranged in groups. Pinboards support these same handy freeform figure arrangements. This also makes them perfect for Kanban visualization boards.

Curio for Flowcharting & Sketching

Notebooks are more than just notes.

Curio includes built-in vector drawing tools for flowcharting and diagramming, plus bitmap pens and brushes for quick sketches when your right-brain needs a chance to express itself. It’s all integrated within Curio.

Curio for Task Tracking

Find and track all of your notes and tasks.

Curio has full support for meta information to find that brilliant idea and to stay on top of your to-do list.

Curio for Annotating

Look forward to your next meeting or lecture.

With integrated PDF annotation tools—plus our amazingly popular Spread PDF feature—you can easily manage handouts and materials. Perfect for classroom or business meeting settings.

Reviews & Sightings

A Personal Note

I’ve always been a huge fan of taking notes, sketching out ideas, and brainstorming. In the past, my notebooks and whiteboards were covered with notes, to-do lists, interface sketches, and much more. I made sure my office had the largest whiteboard possible.

Over 10 years ago, during the development of Curio, the goal was to create a notebook app specifically for designers and other creative types. However, while working on the initial interface and feature set, it dawned on us that a completely freeform environment, much like the notebooks in our hands and the whiteboards around the room, was exactly what we needed to create and not just for designers but for everyone who takes notes and collects ideas.

Curio is now the most innovative note-taking and brainstorming application on the market used by thousands of customers around the world. It’s wonderful to see how people are using Curio and I, personally, have ditched the whiteboard and use Curio for all my visual thinking. I look forward to the next 10 years of amazing Curio development.
