Ever. ✅ Advanced Measurement Tools Smart rulers for pixels, centimeters, and inches. CSS style picker. Automatic layout report generation. 🔥 KEY FEATURES Vibe Project Manager (Offline App) 3 Optimization Modes: None: Full content (ideal for small projects) Smart Minification: Removes comments/whitespace (medium projects) Skeleton Mode: Only class/function structures (huge projects, 10M+ tokens) Core Functions: Smart Delta Diff: Compares old vs new code and generates a Git-style Unified Diff. Provide AI only with the changes, not the whole project. ZIP & Folder Support: Drag & drop React, Vue, Node, HTML, PHP... Flexible Export: Copy to clipboard or download reports as TXT, Markdown (.MD), or PDF. Live Token Counter: Real-time estimation of AI token costs with color indicators (Green/Yellow/Red). Visual Progress Bar: Tracks the entire generation process in two phases (file reading 0→50%, worker optimization 50→100%) with a shimmer animation during the data transfer phase. Stop Button: Interrupt the process at any point. The worker is terminated cleanly and reinitialized for the next run. On-Page Tools (Visual) Smart Ruler: Measure distances (px / cm / inches) Annotator v2: Draw vector arrows, straight lines (hold Shift to lock horizontal/vertical), circles and rectangles (with optional fill color and opacity), and text. Duplicate any object (Ctrl/Cmd+D or the copy button in the layers panel) and organize everything with layer management. Web Extractor: Copy CSS, clean text, or HTML structure with one click. Multilingual & Themes Interface in English, Italian, Spanish, French, German and Portuguese. Dark/Light mode support. 📌 REAL WORLD USE CASES 🎯 Scenario 1: Resume a project in a new AI chat Upload the project, apply Skeleton Mode, copy the context → ChatGPT/Claude understands the architecture immediately without wasting tokens. 🎯 Scenario 2: Report a graphic bug Use Annotator to draw red arrows on the site → Screenshot ready for the team in seconds. 🎯 Scenario 3: Update code without waste Use Smart Delta Diff: the AI sees only the modified lines (+/-), not the entire project. 🎯 Scenario 4: Export your context in multiple formats Generate the project context and export it as TXT for simplicity, Markdown for structured documentation, or PDF for professional sharing — all with a single click. 🔒 PRIVACY & SECURITY ✅ 100% Offline: All files (ZIP, code) are processed in the browser using Web Workers.
