What is the Infinite Blackboard?
The Infinite Blackboard is a premium dark theme canvas designed to emulate a traditional classroom chalkboard. Ideal for complex educational mockups, technical explanations, slide layouts, and drafting, it offers an unrestricted work area with fluid zooming and panning. Write notes, sketch flowcharts, and compile math drafts with zero page boundaries.
Why is it Completely Secure?
Every coordinate path, chalk color, line thickness, and zoom offset is calculated and stored strictly inside your browser environment. Your diagrams never leave your device, ensuring complete confidentiality for corporate roadmaps, academic research, and layout drafts.
How to Share Your Sketches
Click "Share" to compress the entire canvas vector paths into a secure, URL-safe data string. This string is appended to the browser address hash. Copying and sending the link lets anyone rebuild your drawing locally in their browser instantly, removing the need for cloud databases!
Visual Planning & Educational Sketching Tips
- Chalk Contrast: Use soft pastel colors (like yellow, pink, and cyan) on the dark slate to highlight different nodes or terms.
- Technical Drafts: Toggle the "Grid" or "Dots" backgrounds in settings for aligned coding tags, wireframes, or grid math diagrams.
- Recenter instantly: If you pan away, a green arrow appears at the window edge pointing to your content. Tapping it centers the view back instantly.
