About PatentDrawing

PatentDrawing is an AI image generator for inventors, product designers and small teams who need patent-style illustrations of their ideas. Users describe an invention in text or upload a product photo, hand sketch or CAD screenshot, then choose a direction such as black-and-white line art, a 3D-style perspective view, an exploded view, or a flowchart and block diagram.

The workflow is simple: describe or upload the invention, pick a drawing type, then review the result and download it as a high-resolution PNG. Users can refine a drawing by adjusting the prompt or reference and generating another version, which uses additional credits. Results can include multiple requested views such as front, side, top and perspective.

The site is open about limits. Outputs are flat PNG images rather than editable vector files or 3D models, and the tool does not certify patent-office compliance, so labels, geometry and connections need human review before filing. Paid plans are credit-based, include commercial use and no watermark, and sign-up needs no credit card.
