What problem does it solve? Recreating the visual style of a technical diagram for new content is hard: style is more than colors, and ad-hoc prompts produce generic results. FigEcho turns a reference diagram into a reusable, evidence-backed visual fingerprint and a complete modular prompt, so new architecture diagrams, roadmaps, and method figures come out in the same visual family. ## Core Features & Use Cases - Visual Fingerprint Extraction: Distills 5-7 high-distinctiveness style anchors across layout, components, connectors, palette, typography, and iconography, each with evidence and transfer rules. - Three Delivery Modes: prompt-only (standalone style prompt), analysis-and-prompt (style report plus prompt), and image-and-prompt (final PNG plus the exact generation prompt sent to the model). - Style Library: Save, search, rename, validate, and reuse named Style Packs that bundle the full prompt, style spec, and original reference images; ships with 6 example packs. - Use Case: Give it a paper's method-overview figure and your own module list, and it plans the new diagram's topology, fills the style prompt with your content, binds the reference image to an image backend (built-in tool, Labnana, OpenAI, or Gemini), and verifies the render against each style anchor. ## Quick Start Extract the layout, colors, typography, and connector style from this reference architecture diagram and give me a reusable style prompt.
