Pick a shape, click the canvas to drop it, rename it (click once to select, edit in the sidebar), drag to move it. Pick a connector style, click two shapes in order to link them. Works for any project, this file has no dependency on anything else in the series, download it and reuse it standalone.
What this does: turns a plain description into a real diagram, containers grouped by system, six shapes with fixed meaning, connectors that show sync vs async, triggers, rollback paths, and monitoring, plus a legend that builds itself. What usually takes an hour in a drawing tool (place shapes, pick a notation, remember what dashed-red meant last time, redraw when a reviewer asks "wait is this blocking or not") takes under a minute here, and it stays consistent every time because the shapes and lines never change meaning. Works fully offline too, no internet, no account, no key.
Steps to proceed
Describe it below, real names and real relationships beat vague ones.
Click Generate. Get a first-draft diagram in seconds.
Fix labels that need your exact naming, click a block, edit in the sidebar.
Add clock badges on anything with a deadline or expiry.
Export as SVG or PowerPoint and share.

Four ready-made diagrams in different fields, same six shapes, same seven connectors. Loads straight onto the canvas below so you can see, edit, and export a real example before writing your own.
Raw Input → Auto-Generate
Works for any topic, an IT system, a piece of hardware, a biological or medical process, a research project, a thesis, an engineering design, anything with parts that connect to other parts. Paste raw notes, an email, a description, anything. The more concrete, the better the output.
Optional, but worth doing if your description above feels thin. Skip straight to Generate below if you're already confident it's detailed enough.
A few quick questions to sharpen this up:
One button: reads your description with a built-in offline keyword parser and drafts a first pass. Works fully offline, no account, no API key, no setup, the same everywhere it's opened.
Shapes
Connector style
Click a shape, then click a second shape, to draw the selected connector between them.
Selected block
Nothing selected. Click any shape once to select it (a plain click, not a drag).
Canvas
Click any shape once to select and rename it in the box above. Drag to move it. Click the small × to delete it (also removes its connectors). Hover any button for a quick how-to.
