What is DualBoard?
DualBoard is a free, no-signup online whiteboard built specifically for in-person collaboration. Designed for two people sitting across from each other, it solves a common issue: one person always sees the writing upside down. DualBoard fixes this with a mirrored whiteboard view, syncing both users in real time so each sees content from their own perspective.
How DualBoard Works
DualBoard uses a split-screen layout:
- The editor draws on the bottom canvas
- The viewer sees a live, rotated version on the top canvas (flipped 180 degrees)
This allows both people to collaborate naturally, just like using a sheet of paper — without any flipped screens or awkward setups.
Key Features
- No account or registration required — start instantly in any browser
- 100% free and ad-free — no popups, no distractions
- Real-time mirrored canvas — the viewer’s screen is flipped automatically with zero delay
- Full drawing toolkit — pen, eraser, brush sizes, undo/redo
- Works with mouse, stylus, and touch input
- Export drawings as PNG for saving or sharing
- Clean, minimal interface focused on real collaboration
Who Should Use DualBoard
DualBoard is ideal for any face-to-face, one-on-one session, especially when sitting across a table. Use it for:
- Tutoring — math, science, reading, writing, or coding
- Language learning — practicing handwriting or characters
- Art and design — sketching ideas and giving live feedback
- Team collaboration — planning, problem-solving, or brainstorming
If you work closely with someone in person and need a shared drawing space that just works, DualBoard is built for that.
Why DualBoard Is Different
Most whiteboards are built for remote meetings or group collaboration. DualBoard is built for two people in the same room. Its mirrored split-screen design solves the upside-down writing problem instantly, without extra steps. It’s lightweight, fast, and focused on real-time, in-person interaction.
Benefits of Face-to-Face Collaboration with DualBoard
Face-to-face collaboration offers advantages remote tools can’t match. When working together physically:
- Communication is faster and clearer
- Non-verbal cues improve understanding
- Immediate feedback keeps sessions engaging
- Shared physical space boosts focus and reduces distractions
DualBoard enhances these benefits by removing the usual hassle of flipped screens or awkward device handling. This lets both participants stay fully engaged in the session.
