Lumoshot Screenshot Captu

Lumoshot is a screenshot annotation tool that lets you capture, annotate, redact, and copy polished screenshots — all locally, without any account or upload.

Stop wasting time writing long text explanations. Add arrows, spotlights, step numbers, click icons, and speech bubbles in seconds. Hit Cmd+C and paste directly into Slack, Notion, GitHub, or any tool you use.

KEY FEATURES

🔦 Spotlight
Dim the entire screen and highlight only what matters. Instantly guide your viewer's eye — no text needed.

🖱️ Click Icon
Place a cursor icon + radial lines to show exactly where to click. Communicate "click here" without typing a single word.

💬 Speech Bubble
A text callout with a movable tail. Point precisely at any button or field.

🔢 Step Numbers
Auto-incrementing numbered badges (1, 2, 3…). Perfect for documenting flows and tutorials.

💧 Blur / Redact
One-click mosaic to hide personal info, API keys, or anything sensitive before sharing.

🖋️ Arrows, Rectangles, Text
All the essential annotation shapes, with full color and stroke controls.

NON-DESTRUCTIVE EDITING
Every shape stays editable. Reorder Z-index, resize, recolor, or delete at any time — nothing is baked into the image until you export.

KEYBOARD-FIRST WORKFLOW
Left-hand shortcuts (V = select, A = arrow, P = pen, L = spotlight, C = click icon…) keep your right hand on the mouse. Inspired by pro tools like Figma and VS Code.

HOW IT WORKS
1. Capture — Full screen, visible area, or drag to select a region
2. Annotate — Add shapes and effects with keyboard shortcuts
3. Share — Cmd+C to clipboard, then paste anywhere. Or Cmd+S to save.

Everything runs locally in your browser. No data leaves your machine.
