Create a Stack

Once you launch NoteDex you can view all your stacks - and create new stacks. Stacks are just 'stacks' of cards - great for organizing all your projects, notes, ideas, recipes.. the list goes on!

With NoteDex you can customize the image cover of each of your stacks - a very visual way to help you organize your information - choose a project logo, or just a fun image that captures your mood.


Create a New Index Card

When you add a new note card in your stack you will be presented with a life-like render of a 3 x 5 format index card size.  You will see the title, body area, and can also add text and more on the back of the card.

Add Text and Images

One of the standout differentiating features of NoteDex is the ability to add text, insert photos and more.    You will see a full rich-text toolbar of options, you can insert hyperlinks, tables, and symbols. You can type an unlimited amount of text onto each card and even change the background card color


Draw with Digital Ink

Unique to NoteDex is the ability to use your stylus digital ink pen and draw on a card. You can even use your finger or mouse to sketch diagrams!  Unlike other apps, you can draw all over your note cards and even over text and images - ideal to annotate drawings, creating flash cards for learning or for note taking. It's also the only index card note app where you can edit your ink cross platform - not just on a Windows Microsoft Surface Pro or Apple iPad device - using our advanced ink technology on all our index card apps.

Pick an Index Card Template

You can further customize your index cards by adding a custom background template. NoteDex provides a set of supplied index card templates so you can create a ruled index card, and you also just use any image and upload from your computer to make your own.  This is an ideal way to take a picture of a real index card and insert it onto your NoteDex index cards if you want to digitize those priceless family recipe note cards! You can even have different templates on one side and the other!


Keep your Index Cards Organized

After you have created your cards you can organize them into folders (groups) and add tags to categorize. 

Tags can be either unique to a stack or global across all stacks.  Ideal if you are managing different projects or to do lists and don't want to see the tags from another project stack.  You can also mark cards as 'favorites' for quick retrieval as part of your project management or for cards you are trying hard to learn.
