Diagramly

Diagramly is a free web-based diagram maker that generates hand-drawn flowcharts, architecture, and cheat sheets.

Diagramly is an online tool that lets users create hand-drawn system architectures, flowcharts, mind maps, and cheat sheets directly in the browser. It generates diagrams when users type shortcuts like text-to-diagram lines or describe systems to the built-in AI. The platform offers six distinct visual styles, including paper, blueprint, and chalkboard, along with tables, icons, and automated layout tools. Users can export their work as PNG, SVG, PDF, or GIF files, present frames as slide decks, or publish live diagrams via shared links. It is designed for engineers, writers, and presenters who need to quickly sketch and share technical concepts. The service provides a free browser tier alongside a paid Pro subscription that includes cloud saving, version history, and increased AI message limits.
