Don't Just Take Notes.
Master Them Spatially.
Break free from linear documents. Connect ideas with stretchable 360° arrows, render live KaTeX math, fix spelling in real-time, and let our intelligent Active Recall engine turn your whiteboard notes into exam-crushing flashcards.

How does backpropagation compute gradients through hidden layers in deep neural networks?
Hint: Think about composite function derivatives and the chain rule.
Why Linear Notes Fail for Complex Subjects
Linear text files in Notion or Google Docs force ideas into a 1D vertical scroll. Human memory is inherently spatial.
- ✕1D Vertical Trap: Notes are buried 50 pages down in an endless scroll with zero visual hierarchy.
- ✕Passive Illusion of Competence: Re-reading highlighted text creates familiarity without actual cognitive retrieval.
- ✕Context Switching Hell: You juggle a PDF viewer, note app, Anki deck, and math editor across 4 different windows.
- Spatial Memory Palaces: Map concepts 2-dimensionally. Your brain remembers where ideas live in physical relation to each other.
- Built-in Active Recall: Click one button to convert any canvas note into interactive spaced repetition study flashcards.
- All-In-One Toolkit: Live KaTeX math, stretchable 360° arrows, grammar checking, and lecture audio sync on one canvas.
Everything You Need on One Unified Canvas
Engineered from the ground up for students, researchers, engineers, and serious autodidacts.
Active Recall Study Engine
Transform your board notes into interactive flashcards. Test your recall with spaced repetition intervals and track your mastery score over time.
Stretchable 360° Connectors
Draw straight, curved, or elbow arrows that link smoothly across notes, geometric shapes, and process steps with dynamic auto-routing.
Live KaTeX Math Rendering
Write complex formulas, integrals, matrices, and notation with real-time LaTeX parsing and 1-click math symbol inserts.
Grammar & Spell Checker
Integrated LanguageTool engine underlines typos and grammatical mistakes directly inside notes with 1-click replacement popovers.
Slide Frames & Presenter Mode
Group board sections into Slide Frames. Switch instantly into full-screen presentation mode with keyboard navigation.
Lecture Audio Sync & Scrub
Record audio while scribbling or taking notes. Notes remember the audio second so you can scrub lecture recordings in one tap.
Cornell Note Framework
Cues, detailed lecture notes, and synthesized summary sections.
Concept Linking Map
Organize parent ideas and child nodes with directional connectors.
Exam Cram & Recall
High-yield study points formatted for the active recall engine.
System Architecture
Map microservices, databases, and message queues with geometric shapes.
Frequently Asked Questions
Is EduBoard really 100% free right now?
Yes! While we are in public beta, all features — including infinite canvases, stretchable 360° arrows, KaTeX live math, active recall quizzes, and slide frames — are 100% free with zero paywalls or credit card requirements.
How does the Active Recall Study Engine work?
Whenever you create study notes, formulas, or shapes on your canvas, EduBoard automatically parses concept titles, cue phrases, and definitions into interactive study cards. You can trigger Active Recall mode anytime to test yourself with spaced repetition difficulty ratings.
Can I export my boards to Obsidian or Notion?
Yes! EduBoard includes a dedicated 1-click Markdown Exporter that transforms your sticky notes, concept lists, and equations into standard Markdown files with metadata frontmatter, ready to drop into Obsidian or Notion.
Does it work on iPad, tablets, and mobile devices?
Yes. EduBoard is optimized for touch gestures, Apple Pencil, and styluses, with responsive bottom toolbars and seamless pinch-to-zoom and two-finger panning.
Can I use EduBoard offline?
Yes. Your canvases are cached locally on your device, allowing you to sketch, study, and organize even when you are disconnected in lecture halls or flights.
