After testing dozens of brand guides, here's what gets the best extraction results:
Do:
✅ Use text-based PDFs (not scanned images)
✅ Include hex codes next to color swatches
✅ Clearly label fonts with their exact names
✅ Use consistent section headings
✅ Include a "specs page" with all values in text format
Avoid:
❌ Image-only PDFs (OCR is less accurate)
❌ Colors shown only as visual swatches without codes
❌ Fonts displayed without naming them
❌ Vague guidelines without specific rules
Pro tip: If your current guide is image-heavy, consider adding a text appendix at the end with all the specs in plain text. The AI will pick these up reliably.
