Screenshot · Annotate · Pin · Scrolling capture — a fast, no-fuss screenshot tool for Windows

Features

Capture

• Global F1 hotkey freezes the screen — what you see is what you capture; hover to snap to windows, hold Shift to snap to individual UI elements (buttons, inputs — via UIAutomation)
• Free selection with 8-way resize handles; arrow keys nudge by 1px, Ctrl+arrows resize by 1px, Shift for ×10 steps; Ctrl+A (or clicking empty desktop) grabs the whole screen
• Magnifier with live coordinates and pixel color; press C to copy HEX (Shift+C for RGB) — a color picker built right in

Annotate

• Rectangle / ellipse / arrow / pen / marker / text / numbered badge / mosaic / blur — nine tools in a compact icon toolbar
• Every item stays editable: drag to resize, change color and width, double-click text to edit — with full undo/redo

Pin

• Pin a capture to the screen in one click, or press F3 to pin the clipboard; wheel to zoom, drag edges to resize, Ctrl+wheel for opacity
• Space folds into a slim bar, R rotates, H flips, click-through mode available
• Pins survive restarts — position, scale, opacity and folded state are all remembered

Scrolling capture

• Turn any selection into a scrolling capture with one toolbar click; manual and auto-scroll, 30fps frame grabbing keeps up with fast scrolling
• Multi-band NCC matching with sticky header/footer detection; a live preview strip sits beside the capture area so misalignment is visible immediately
• Falls back to PageDown injection when wheel events are ignored; finish with copy, pin or save

Extract text & translate in place

• Extract text: OCR the selection straight to your clipboard
• Translate: OCR each line with its position, translate, then draw the translations over the original text — the result is pinned exactly over the source region; press Esc to restore
• Bring your own services, configured in Settings: OpenAI-compatible vision/chat models, Umi-OCR (local), DeepL, DeepLX (self-hosted), or Baidu Translate

Output & history

• Filename templates ({yyyy}{MM}{dd}{HH}{mm}{ss}), PNG/JPEG with quality control, optional auto-save on copy
• Capture history keeps recent shots — browse from the tray to re-copy, pin or save them again

Install
