Show HN: DualBoard – a collaborative whiteboard for face-to-face tutoring

DualBoard – Split-Screen Whiteboard for Face-to-Face Tutoring

Purpose: DualBoard solves a common problem in face-to-face tutoring and teaching. When an instructor sits across from a student and draws on a traditional whiteboard or tablet, the student sees everything upside-down, making it hard to follow.

While sitting side-by-side can avoid this issue, many find it more engaging and natural to face each other during tutoring or study sessions. DualBoard lets you do that without the awkwardness of flipping devices or screens.

How It Works:

The tutor draws on the bottom canvas (Editor View) using mouse, stylus, or touch input.

The top canvas (Viewer View) automatically shows a 180-degree rotated version of everything drawn below.

So when the tutor writes “HELLO” normally, the student sees “HELLO” right-side up from their perspective.

Use Cases:

Math tutoring (equations, graphs, problem solving)

Language learning (writing practice, character formation)

Art instruction

Technical drawing and diagrams

Any face-to-face visual instruction setting

DualBoard eliminates the need to physically rotate devices or awkwardly position screens, making tutoring more comfortable and effective for both tutor and student.
