What Lumina actually does
Five ways to frame it
Visible area, full page with seamless stitching, a single element, a drawn region, or a delayed shot for menus and hover states. Every mode, pixel-perfect.
- Full-page stitch without seams
- Element picker with DOM precision
- Delayed capture for transient UI
Non-destructive, like it should be
A real layer-based editor: annotations, crops, backgrounds, and device mockups that stay editable forever. Change your mind a week later.
- Layer-based annotation
- Device and browser mockup frames
- Backgrounds, shadows, padding presets
Vision AI that never phones home
Gemini Nano runs on-device to name screenshots, extract text, auto-redact PII, and pull design tokens from UI captures.
- Auto-naming and OCR on-device
- PII auto-redaction
- Design token extractor for UI shots
Every capture, one search away
Screenshots land in a searchable local library, indexed by OCR text and AI labels. Find that error dialog from three weeks ago in seconds.
- Full-text search over OCR
- Before/after diff view
- IndexedDB — nothing leaves your machine
From capture to deliverable
Export PNG, WebP, or a searchable PDF with embedded OCR text. Copy to clipboard, save to disk, or batch-export a whole session.
- Searchable PDF with OCR layer
- PNG / WebP with quality control
- Batch export
