About CaptureKit — Screenshot, Recorder & Annotation

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).
