Eraser AI

AI diagrams from prompts for engineering and architecture

DesignFreemiumLLM-drafted

Part of this entry was LLM-drafted and is being polished.

Eraser AI generates technical diagrams from prompts — system architecture, sequence diagrams, ER diagrams, flowcharts. Output as editable Mermaid / SVG. Loved by engineers documenting systems.

Editor's verdict

Best AI tool for technical diagrams — beats hand-drawing in Whimsical / Excalidraw / Lucidchart for first-draft architecture. Mermaid output means you can version-control diagrams in your repo. For non-technical diagrams (org charts, mind maps), Whimsical / Miro AI cover those better.
