Paste Pen

Paste Pen A portable app for drawing over the Windows screen, taking screenshots and inserting images with build in background removal. An extended alternative to Epic Pen and gInk. Perfectly suited for AI coding interactions, Presentations and Trading with charts overlay.". No installation required, fully open-source app.

💡 The idea for this app came from my dissatisfaction with how existing alternatives handle inserting images over the desktop. I decided to eliminate this shortcoming in my own app and include all the features I personally needed. Especially, I wanted a feature for inserting charts with the ability to stretch them, transform and remove the background.

Drawing & Tools:

• Draw with the left and right mouse buttons in different colors simultaneously.
• Tools: Pen, Laser Pointer, Shapes (Line, Rectangle, Ellipse, Arrow), Text, Eraser.
• Flexible color and size selection for pen, shapes, text, and eraser.
• Selecting a font for text, moving, rotating, and scaling.
• Smart vector eraser: LMB erases pixels; RMB deletes an entire line or shape with a single click.
• Image Handling
• Smart Cut — a tool for adjusting the design of apps and websites right on your desktop and preparing a task for the AI to modify the code (automatically fills the cropped area's background with a color sampled from the original screen, seamlessly blending it with your desktop).
• Insert from a file or the clipboard: move, scale proportionally or freely, reshape.
• Background removal for inserted images — available at any time after insertion. The result can be saved back to disk.
• Insert chart feature with the ability to stretch them and remove the background.
• Layer management: bring images to the front or send them to the back.
• Presentation Mode (Insert Folder)
• Insert Folder without Background: each file is automatically stripped of its background as you scroll.
• Laser pointer (a red glowing dot) can be toggled on top of any active tool.
