FlashCap

Capture, redact, and hand off. A macOS screenshot, annotation, and OCR tool.

Select a region, draw arrows on the shot, mosaic out what you do not want to share, and drag it straight into Slack. It can also just read the text off your screen and put it on the clipboard.

Features

• Region-select screenshots, plus timer capture at 3 / 5 / 10 seconds so you can catch open menus and hover states
• Arrow annotations (color, thickness, white outline, drop shadow) and mosaic / blur / fill masks for hiding personal information before you share
• OCR through the macOS Vision Framework (Japanese and English). Recognition runs on device, so the image never leaves your machine
• Headless OCR for when you only want the text — flashcap --capture-screen-text or open flashcap://ocr runs select, recognize, copy to clipboard, notify, and quit in one shot. Bind it to an Alfred or Raycast hotkey
• Screen recording of a selected region, exported to MP4 or animated GIF (trim, fps, and size)
• Drag the finished image straight into Slack, or copy either the image or its file path to the clipboard

Requirements & notes

• macOS only. It relies on screencapture for capture and the Vision Framework for recognition, so there is no Windows build.
• A universal binary (Intel / Apple Silicon), signed with a Developer ID certificate and notarized by Apple, so Gatekeeper does not warn.
• macOS asks for Screen Recording permission on your first capture (System Settings → Privacy & Security → Screen Recording).
• OCR uses /usr/bin/swift from the Xcode Command Line Tools; run xcode-select --install if it fails. Exporting video requires ffmpeg.
• Open source under the MIT License.
