Lumina — Professional Screenshots

Pro screenshots, a non-destructive editor, and private on-device AI — captured, annotated, and organized. All local. All yours.

Lumina — Professional screenshots. Private. Intelligent. Beautiful. Most screenshot tools stop at "click, save, done." Lumina starts there and keeps going — a full capture engine, a real annotation editor, on-device AI, and a searchable local library, all in one fast, private extension. Nothing leaves your machine unless you say so. 📸 Capture anything, pixel-perfect Visible viewport, in one keystroke Full-page — scrolls and stitches long pages flawlessly Element & container-aware selection Drag-to-select any region Delayed capture for hover states and menus Clean mode hides sticky bars and floating junk ✏️ A non-destructive, pro-grade editor Arrows, shapes, text, freehand pen, highlights, blur/redact, and numbered steps — all on a real layer model with undo/redo, lock/visibility, and reordering. Keyboard-first (V A R E L T P H B N), so you never reach for the mouse. 🧠 Private, on-device AI Powered by Chrome's built-in Gemini Nano — your pixels never leave the device. One click to describe & improve, summarize, run an accessibility audit, generate React + Tailwind code, extract JSON, translate, or auto-detect and redact PII. Bring your own OpenAI, Anthropic, Gemini, or Grok key only if you want to. 🗂️ A library that actually remembers Every shot is saved locally with thumbnails and rich metadata. Full-text search across titles, URLs, AI descriptions, tags, and OCR text. Organize with projects, folders, and favorites. 🚀 Export beautifully PNG, JPEG, WebP, copy to clipboard, or a searchable PDF with an invisible OCR text layer. Wrap shots in browser, MacBook, or iPhone mockups with real shadows and gradients. Pull color palettes and design tokens straight from the pixels. 🔒 Private by design Local-first, always. Screenshots, thumbnails, and metadata live in your browser via IndexedDB. OCR and AI run on-device. No analytics. No telemetry. No forced cloud sync. No account. ⌨️ Built for speed Command palette (Ctrl/⌘+K), a floating quick-actions bar right after capture, and global shortcuts for everything. Capture it. Mark it up. Understand it. Keep it. All in Lumina.
