Card Types
There’s 2 types of cards:
- Standard Cards
- Annotation Cards
Standard Cards are stand-alone cards that support text, images, audio recordings, equations and drawings. Annotation Cards are cards created by labeling regions of an image. They stay linked to their original image to preserve their original context.
Standard Cards
Standard Cards use any combination of text, images, audio recordings, equations and drawings for the question and answer. These are the most common and versatile types of cards.
Creating Standard Cards
On iPhone & iPad Tap on the + menu, then tap on New Card.
On Mac Click on the + button on the toolbar.
On Mac & iPad Click on File -> New Card in the menu bar.
New cards are added to the folder you are currently in.
Add Content to Standard Cards
Add more than text to a Standard Card by using the Ellipsis (…) menu beside the question or answer. Choose the content type you want to use for that side of the card.
Images
Choose Camera, Photo Library or a file to add an image.
On iPad & Mac You can also drag and drop images into the question or answer area to replace the current question or answer.
Audio Recordings
Choose Audio Recording to record audio directly in the card editor. A Standard Card can use audio for the question, the answer, or both.
With Advanced Learner, new recordings can be transcribed automatically. The transcript appears as editable text with the audio, so you can study, search, print and export the card with readable text while keeping the original recording.
If a recording was not transcribed, use Transcribe Audio from the audio block menu to create transcript text later.
Equations
With Advanced Learner, choose Equation to add a LaTeX equation to the question or answer. LaTeX is a text notation for writing math. You type commands such as \frac{x}{y} or \sqrt{64}, and Benkyo Box renders them as formatted equations.
The equation editor shows your LaTeX source at the top and a live Preview below it.
To add an equation:
- Open the Ellipsis (…) menu beside the question or answer.
- Choose Equation.
- Type or insert the LaTeX you want.
- Check the Preview.
- Tap or click Save.
Type \ to start autocomplete for LaTeX commands. Keep typing to filter the suggestions by command, such as \sqrt, or by the snippet name, such as superscript.
Use Tab to move to the next curly-brace placeholder in the equation. Use Shift-Tab to move back. On iPhone and iPad, use the previous and next placeholder buttons in the equation toolbar.
Use the equation toolbar to insert common snippets without typing them by hand. Quick buttons insert fractions, superscripts, subscripts, square roots, multiplication signs and text blocks. Menus let you browse categories such as Accents, Arrows, Colors, Functions, Greek Letters, Operators, Relations, Sets and Structures.
Drawings (iPad and iPhone Only)
By selecting Sketch on the question or answer's Ellipsis (…) menu, you can doodle your question or answer on a blank canvas:
Additionally, tapping on an image brings the Drawing Editor for the image. This enables adding markers and labels to the image, which is useful for arrows, hints and covering areas of the image.
Annotation Cards
Annotation Cards are a type of card used for learning from labeled regions in an image. This is useful for learning parts of a diagram or photo. The original image is preserved, helping you create a mental connection between the question, answer and their original context.
Creating Annotation Cards
On iPhone & iPad Tap on the + menu, then on From Photos or From Camera, both under New Annotation Cards.
On Mac Click on the New Annotation Cards 
button on the toolbar.
This will launch an image picker or the camera. Once you finish selecting an image, you can start adding annotations using the Add Annotation 
button, which will add an Annotation Card in the middle of the image or wherever there's space.
The area that it encloses is the question. The answer is the text area below it. To edit this Annotation Card:
- Drag its corners to resize it
- Tap on the text area to edit its answer
- On iPhone or iPad Tap and hold on the middle of the annotation area to move it around
You can add more than 1 annotation to the image. They are all independent cards that can be studied and organized separately, but they are all linked to the original image.
