VAS · User Guide
From toolbar to editor, capture to annotation — a complete, chapter-by-chapter walkthrough of every feature.
- 1
Open it
Install from the App Store and open it: a toolbar floats onto your desktop (drag it anywhere), and a bottle appears in the top-right of your menu bar. Want it lower-key? Turn on the breathing light from the user-guide button — the toolbar shrinks to a 120×6px sliver of light, and one click summons it back.

Grant access
On your first capture, macOS asks for Screen Recording permission (for screenshots) — just switch VAS on in the list (System Settings → Privacy & Security → Screen Recording). For web-page capture, macOS asks for Accessibility permission (for auto-scroll) — same steps (System Settings → Privacy & Security → Accessibility). Every screenshot, OCR and QR scan is processed on-device — nothing uploaded, nothing analyzed.

Capture
Pick a mode (Fullscreen ⌥⌘1, Window ⌥⌘2, Region ⌥⌘X), frame the shot → edit in the editor → use “drag-to-export” to drop it into any window. A smooth, flowing editing experience.
That floating toolbar on your desktop — from folding into and summoning the breathing light, to the four capture modes, color picker, ruler, delay and batch: what every single button does.
Where the work happens after capture — a four-zone interface, 12 annotation tools × properties, freely combined into the alchemy recipes you want.
Another mode of the same editor: frame-by-frame device animation, plus pixel art for beads and stitch charts — printable charts and machine-readable JSON both come out of it.
Read the text on your screen, mask what shouldn't leak, and scan the intent behind a QR Code — three things, none of them in the cloud.
The powers that let annotations grow into order — smart snap guides, multi-select align & distribute, grouping and layer order.
Every way in and out of VAS. The signature drag / paste import (the toolbar opens to catch your image), drag-to-export, clipboard, ShareSheet, seven save formats and batch watermarking.
Tool switching, canvas, editing, object operations, plus customizable global shortcuts — a full reference, for lookup.
