Notes

Notes are the most versatile card type in ThinkEx. They use the BlockNote editor, which provides a rich-text editing experience similar to Notion.

​
Rich-Text Editing

The BlockNote editor supports:
  • Text formatting: Bold, italic, underline, strikethrough, code
  • Headings: Multiple heading levels for document structure
  • Lists: Bulleted and numbered lists with nesting
  • Code blocks: Syntax-highlighted code with language selection
  • Math: Inline and block-level LaTeX equations
  • Images: Embedded images with captions
  • Tables: Structured data in table format
  • Quotes: Blockquotes for highlighting text

​

​
Updating Flashcard Decks

Add more cards to existing decks by asking the AI:

Flashcard decks work great alongside notes and PDFs. Study from the same workspace where you keep your reference materials!

​
Quizzes

Quizzes provide interactive testing with multiple choice and true/false questions.

​

​
Creating Quizzes

Ask the AI to generate quizzes from your content:

The AI will analyze your notes and generate relevant questions with explanations.

​
Folders

Folders help you organize related cards into collections. They appear as special cards on your canvas.

​
Using Folders

1

Create a folder

Click + and select “Folder” or ask the AI to create one
2

Add cards to the folder

Drag cards onto the folder or use the card menu to move them

ThinkEx uses a flat folder structure - cards can belong to one folder, but folders cannot be nested inside other folders.

​
Card Properties

All cards share common properties:
  • Name: The card’s title (editable)
  • Subtitle: Secondary text shown under the title
  • Color: Background color for visual organization
  • Layout: Position and size on the canvas

​
Responsive Layouts

Cards automatically adapt to different screen sizes:

  • Mobile (xxs): Single-column layout

​

Every card supports these actions:
  • Resize: Drag the corners to adjust card size
  • Move: Drag to reposition on the canvas
  • Rename: Click the title to edit
