CopyToLLM
One hotkey to capture any screen region and auto-paste it into ChatGPT, Claude, or Gemini - image + prompt, zero friction.
CopyToLLM is a background Windows utility that captures any screen region and delivers it straight to your favorite AI chat - fully automated.
Press Ctrl+Shift+S anywhere - a snipping overlay appears - drag a region (or click for auto-element detection, Alt+Click for scroll capture, double-click for full screen) - pick ChatGPT, Claude, or Gemini - the tool opens Chrome, pastes the image, and types an analysis prompt. All in one flow.
The scroll capture engine is the crown jewel: it auto-scrolls any UI element, captures each frame, and pixel-stitches them into one seamless full-length screenshot using MAE matching. Works on code editors, web pages, chat logs - anything scrollable.
Built it because I got tired of screenshot, save, open AI, upload, type prompt, wait. Now it is one hotkey. Zero NuGet dependencies, pure .NET 9 + Win32 interop.
Snap any part of your screen and instantly drop it into your favorite AI chat like ChatGPT with just one hotkey—no fuss, no delays, pure productivity magic! Perfect for when words alone just won’t cut it.
