Sketch2scheme

Sketch2scheme is a web-based tool that converts hand-drawn flowcharts, diagrams, and sketches into digital, editable schemes using artificial intelligence. Users can photograph or upload images of their manual drawings, and the system automatically recognizes shapes, arrows, text, and connections, then transforms them into a clean digital format. The resulting digital diagrams can be further refined through a built-in visual editor that allows repositioning, resizing, recoloring, and relabeling elements. Alternatively, users can switch to a Mermaid code editor—a text-based diagramming language—to make precise adjustments, generate JSON definitions, or export the diagram in various formats for documentation, presentations, or integration with other software. Beyond sketch recognition, Sketch2scheme offers a text-to-diagram feature: users can type a description of a process, system architecture, or workflow (e.g., “a login flow with three decision points and two error states”), and the AI will generate a corresponding flowchart or diagram automatically. This capability is useful for quickly prototyping ideas from meeting notes or brainstorming sessions without any drawing. The platform also includes an image editor for basic enhancements—cropping, rotating, adjusting brightness or contrast, and adding annotations—so users can polish uploaded sketches before conversion. Once a diagram is digital, it can be exported as PNG, SVG, or PDF, or copied as Mermaid code for use in GitHub, Notion, or other Markdown-compatible tools. Sketch2scheme targets professionals and students who frequently work with diagrams: software engineers designing system architectures, product managers mapping user journeys, educators explaining processes, researchers documenting workflows, and anyone w
