FAQ

Is this really free?

Yes, for the first few uses. Every visitor gets 3 free AI-powered extractions total, shared with the Drawing Revision Comparator since both use the same underlying AI call. After that, a paid tier is coming.

Is my data stored?

No accounts, no file database. Your PDF is converted to images and sent to Claude's vision API (or an alternate AI provider if configured) to read the drawing, and the result goes straight back to your browser. Nothing is kept on the server afterward.

What are the risks?

Because this uses a third-party AI API, avoid uploading drawings with information you're not allowed to share externally, trade secrets, ITAR-controlled data, or NDA-covered designs. GD&T recognition is best-effort, always verify extracted dimensions and tolerances against the original drawing before using them downstream.

What file types and sizes are supported?

PDF only, up to 15MB, first 5 pages of a multi-page file.
