Everything you need to know about Draft AI.

Draft AI supports PNG, JPEG, WEBP, and PDF files up to 10MB. It works with all types of engineering drawings — detail drawings, assembly drawings, section views, isometric views, and more. Both first-angle and third-angle projections are supported.
Draft AI uses GPT-4o Vision, one of the most advanced multimodal AI models available. For dimension extraction, accuracy is typically 90-95% on clear drawings. For GD&T and standards analysis, the AI follows ASME Y14.5 and ISO GPS rigorously. We always recommend final human verification for production-critical decisions.
Yes. Your drawings are processed in real-time and never stored permanently on our servers. Images are sent to OpenAI's API for analysis and are not used for training. Enterprise customers can opt for on-premise deployment for complete data isolation.
Absolutely. There are no long-term contracts. You can cancel your Pro subscription at any time and you'll retain access until the end of your billing period. Annual plans are refundable within the first 14 days.
The free plan gives you 2 AI analyses per hour — enough to evaluate Draft AI for your workflow. You get access to dimension detection, GD&T analysis, material recommendations, and the conversational AI. Batch analysis, Excel/PDF export, and standards checking require Pro.
Yes! Enterprise plans include unlimited analyses, API access, team management with role-based permissions, SSO/SAML authentication, and a dedicated account manager. Contact our sales team for a custom quote tailored to your organization's needs.
