SpectraLens AI is an all-in-one in-browser productivity companion that allows you to query multiple AI models simultaneously, scan and extract on-screen elements with offline OCR, and unblock restricted text selection without leaving your active tab. 🚀 KEY CAPABILITIES & FEATURES: 1. Simultaneous Multi-Model AI Querying • Send prompts simultaneously to multiple leading AI providers in parallel. • Compare responses side-by-side in a sleek, glassmorphic floating window. • Zero API Costs: Operates directly with your active web sessions without needing paid API tokens or subscription keys. • Stream responses smoothly with independent model cancellation and stop-fetch controls. 2. Visual Element Scanner & On-Device OCR • Point-and-click to scan any webpage element (paragraphs, tables, charts, or code blocks) directly into your prompt. • Built-in offline WebAssembly OCR engine extracts text from images and diagrams entirely in local browser memory. • Automatic structured DOM parsing formats HTML tables into clean Markdown tables and code snippets into fenced code blocks. 3. Adaptive Theme Engine & Ergonomic UI • 3-State Theme Harmonization: 'Page Theme' dynamically detects host website background colors and luminance to blend seamlessly, alongside dedicated Dark Mode and Light Mode. • Draggable, resizable, and auto-minimizing floating launcher with persistent position memory. • Full Keyboard Shortcut support: - Option + A (Alt + A) to toggle the floating assistant. - Ctrl + Shift + S (Cmd + Shift + S) for Visual Element Selector. 4.
