Build multi-capture grids, persistent capture libraries, visual privacy face review, Share Studio presets, and Shortcuts workflows in OneMark Capture.
OneMark Capture is a focused screenshot markup app for the moment between noticing something and explaining it clearly.
Capture a region, window, or full screen. Mark the image with arrows, lines, shapes, text, markers, pen, highlighter, blur, redaction, and crop tools. Arrange multiple captures in a 1 x 1 through 3 x 3 Capture Grid, keep recent captures in a private local Capture Library, and save editable .onemark projects when you want to return later.
Review recognized text with local Apple Vision OCR, summarize text when Apple Intelligence is available, and apply review-first smart redaction suggestions for sensitive text and on-device Visual Privacy face candidates. Then copy, share, drag, export, create a local AI Handoff bundle, or compose a polished Share Studio output.
OneMark Capture is designed for support notes, bug reports, QA reviews, documentation snippets, product feedback, and quick handoff images. It runs as a Dock app and menu bar utility, supports app-local capture shortcuts, and exposes foreground Shortcuts and Siri actions that keep capture, review, output, and handoff decisions visible.
Highlights:
- Capture a region, window, or full screen, with optional timers.
- Arrange incoming captures, pasted images, history items, and library items in Capture Grid layouts up to 3 x 3.
- Keep a private local Capture Library with thumbnails, source, date, size, optional OCR summary, and optional linked project metadata.
- Annotate with fast visual tools and editable marks.
- Rotate, mirror, zoom, crop, and expand the canvas when marks cross an edge.
- Scan screenshots locally with Apple Vision OCR.
- Review sensitive-text and on-device Visual Privacy face suggestions before applying solid redactions.
- Summarize recognized text when Apple Intelligence is available.
- Save self-contained .onemark projects, including grid state, OCR review state, Handoff prompt text, and Share Studio composition state when used.
- Compose polished Share Studio exports with exact sizes, named presets, and saved logos.
- Create local, inspectable AI Handoff bundles when you choose.
- Use foreground Shortcuts and Siri actions for repeatable capture, OCR, text copy, AI Handoff, export, and project bookmark workflows.
Privacy is local first. OneMark Capture does not upload screenshots, recognized text, redacted exports, AI Handoff bundles, or editable project files to OneMark Capture servers or third-party AI services. You decide when to copy, share, export, save, or upload anything elsewhere.
