Sketch2scheme

Sketch2scheme converts photos of hand-drawn flowcharts, wiring diagrams, floor plans and whiteboards into editable diagrams, keeping the original layout and labels. Results open in a built-in draw.io editor and export as PNG, SVG or .drawio files.

Sketch2scheme is a conversion tool for people who think on paper. Photograph a hand-drawn flowchart, wiring schematic, floor plan, org chart, mind map or whiteboard session, and the service redraws it as a clean digital diagram that preserves the layout and wording of the original. Rather than generating a plausible but rearranged picture, it attempts to place every shape, symbol, line and label where the author actually drew it, then aligns the result neatly. The output opens in a full draw.io editor built into the product, with the source photo displayed alongside for comparison. From there, shapes can be moved, text corrected and connections added. Exports include PNG (still editable in draw.io later), SVG for resolution-independent use, and a native .drawio file that opens in draw.io, Confluence or VS Code; PDF, Visio and Google Drive exports are available by round-tripping through diagrams.net. A conversion typically takes between 10 and 60 seconds. Wiring diagrams are the standout use case. Boats, vans, RVs, home circuits and breadboard electronics are redrawn with draw.io electrical library symbols rather than generic boxes, and ratings such as 10A, 24V or 6mm squared stay attached to the correct components. Wires run at right angles with junction dots at joins. The site is explicit that the result is a drawing aid: connections can be misread, so the diagram must be checked against the sketch before anyone wires anything. The audience is broad: electricians and van converters, software architects sketching pipelines, facilities and architecture people, students, and anyone who fills notebooks and whiteboards faster than they fill diagram software. Compared with manual redrawing in draw.io or Visio, the saving is in transcription and symbol hunting rather than in design decisions, and the layout-preserving approach separates it from general image generators that would invent a new arrangement. The site is built for phones, so a photo can be taken and converted on the spot.
