Release Notes
OneMark Capture 1.0
OneMark Capture 1.0 focuses on the fast screenshot loop: capture what is on screen, mark it clearly, inspect or summarize recognized text, and save, share, export, or hand off the result.
Capture timers
Region, window, and full-screen capture controls start with the timer off, can count down before capture, and remember the last off/on and seconds choice.
New OneMark Capture windows
Command-N and File > New OneMark Capture Window open another blank white canvas without replacing the current window.
Annotation tools for fast visual explanation
Add arrows, lines, rectangles, ellipses, text, numbered markers, pen, highlighter, blur, redaction, rectangle crop, and ellipse crop.
Image / Canvas transforms
Rotate the image and canvas clockwise or counterclockwise, or flip horizontally and vertically, while keeping marks and crop regions aligned.
OCR / Smart Redaction
Scan screenshots locally with Apple Vision, inspect recognized text, and review grouped sensitive-text suggestions with source-aware review counts before applying redactions.
Apple Intelligence Text Summary
Summarize OCR/captured text when Apple Intelligence is available, while keeping recognized text selectable when it is not.
Editable projects
Save self-contained .onemark project files that preserve editable annotations and can include OCR text, review state, summaries, and prompt text.
Flattened output
Copy a default PNG, use the native share sheet, drag an output file, or export PNG/JPEG with scale and background options.
Local handoff workflows
AI Handoff bundles are local and inspectable, with a redacted image, recognized text, context metadata, and editable prompt.md.
Share Studio Product Launch compositions
Compose the current flattened snapshot with aspect ratio, exact output size, stage, frame, caption, saved logo, and format controls.
