Windows On-Screen Writing Tool

Job ID: 40224605

Budget: ₹600 – ₹1,500 INR

I need a lightweight, standalone .exe that lets me write directly on top of any Windows desktop for live Teaching/Tutoring sessions. Core functionality has to feel as natural as a whiteboard:

• Drawing tools with pressure-sensitive freehand lines
• Unlimited undo / redo
• An “infinite” canvas that scrolls or drags freely so I can move the work area by hand
• Simple file import (PDF, PNG, JPG) to annotate over existing material

A clean interface is more important than bells and whistles, but the engine must stay fast even on mid-range laptops running Windows 10/11. I’m open to your preferred framework—Electron, WPF, C++, or another—so long as the final deliverable is a single installer or portable .exe.

Please include:
1. A brief outline of the tech stack you propose
2. Estimated development timeline
3. Any similar tools you’ve built that demonstrate smooth ink rendering or canvas management

Source code and full usage rights will be part of the hand-off.
