CaptureKit — Screenshot, Recorder & Annotation

About

CaptureKit is everything paid screenshot + screen recording tools do — done locally, in your browser, with no account, no upload, and no monthly fee.

✂ **Region capture** — drag-select any rectangle (`Alt+Shift+S`)
📜 **Full-page capture** — auto-scrolls and stitches entire scrollable pages, hiding sticky headers (`Alt+Shift+F`)
📸 **Visible viewport** + **DOM element picker** + **Article-only** modes
🎬 **Screen recording** — tab, window, or full screen, with mic + webcam picture-in-picture overlay (`Alt+Shift+R`)
✏ **Annotation editor** — arrow, rectangle, text, blur, crop tools with custom colors & thickness, undo/redo
🕶 **Auto-redact** — regex-based blurring of API keys, JWTs, credit cards (Luhn-validated), emails, secrets — before they ever hit your screen
🗂 **Local history** — last 30 days (configurable) of captures, viewable in the Options page
🌍 **8 languages** — EN, TR, ES, DE, FR, PT, IT, JA
🎨 Auto / light / dark themes

### Why CaptureKit instead of `Win+Shift+S` or PrtScn?

✓ Full-page (not just viewport) — single image of an entire scrollable page
✓ Built-in screen recording with webcam overlay + mic — no separate app needed
✓ Annotation tools inline — no exporting to Photoshop
✓ Auto-redact secrets — never accidentally screenshot your API keys into Slack
✓ Persistent searchable local history — find that bug report from 3 weeks ago
✓ Keyboard-driven workflow with customizable shortcuts

### Privacy

**Zero cloud. Zero accounts. Zero telemetry.** All captures live in IndexedDB on your device. Settings sync via Chrome's built-in `storage.sync` only (encrypted by Google in transit). No CaptureKit server exists. Open-source (MIT).
